T7 Wind & Noise Management

[prowlnS10]

If you are a taller or even a mid-sized rider the oem T7 set up provides frustrating amounts of buffeting & noise. Many of the early T7 aftermarket windscreen offerings (Puig, Ermax, T7 Rally, Powerbronze) mostly emulated the oem shape & width, that while increasing the height of wind deflection, did little to address the other issues that are inherent in the T7 forward & upright windscreen/faring design. Skidmarx, Givi, V-Stream & more recently Madstad designed wider/reshaped windscreens in multiple heights. 

 

Here's my journey over the past 2 years in search of improved wind management for road riding combined with adjustability for off-road & hot weather riding. As I have aged my sensitivity to noise & related fatigue have increased, so have modified most of my bikes over the past 15 years in search of quieter riding envelopes. My design goal was to have a dual height windscreen that I looked over, not through at both the low & high settings while seated that improved rider air management/noise & did not add adverse handling characteristics. I'm 187 cm (6'1") with a long upper body & 83.8 cm (33") inseam, have standard oem seat (upgraded to customized taller oem seat & then a Seat Concepts Sport Touring seat), wear a Nexx X.WED2 full face helmet & ride mostly 70/30 road/off-road.

 

Link to my Blog for my Canadian 2021 Tenere 700 that chronicles in more detail my T7 air management journey, hopefully it might be helpful & at the minimum be a resource with it's many product links. 

 

T7 Air Management Basics   

                                                                                                                                                                                                                                                                                                                                                                                                                                               

Just adding adjustable windscreen brackets (several are now available) may work ok in the low position & if your head height is within the still air zone, but create air mismanagement issues when in the higher positions by allowing too much uncontrolled air under the windscreen bisected by the instrumentation panel. Improving laminar flow by adding a plate behind the windscreen/in front of the dash panel directing air up the inside of the windscreen is a long accepted practice to equalize/minimize the air speed/pressure differences on both surfaces of the windscreen so that a less turbulent air flow comes off the top edge of the windscreen. High pressure air on the outside surface will curl inwards over the top edge if the inside surface is low pressure, creating eddies resulting in increased buffeting/noise...the greater the difference in pressure the larger/stronger the eddies & buffeting/noise. Improved laminar flow can extend the height of the still air allowing for use of a shorter windscreen providing better sightlines, however, it is possible to have good laminar flow, but if the windscreen is of insufficient height, shape, width & position the air flow can still hit you in an undesirable location such as your head. MadStad is the only manufacturer, so far, to incorporate a laminar flow plate into their adjustable mounting hardware with their Adjustable Windscreen System for the T7. I have not personally experienced  the MadStad setup, but based on other's positive comments this should make a comprehensive & effective start for anyone seeking improved wind, noise, buffeting management combining most of the elements desired for the T7: wider, taller & better shaped windscreen, adjustable height & angle + integrated laminar flow plate that adds rigidity to the oem windscreen mount...although the 'function over form' aesthetics may not appeal to everyone. 

 

Another air management issue applies to spill over air around the sides of the windscreen (including the void to allow room for hand guards when the bars are lock to lock), tank & body work, of which the T7 benefits from better shaped/wider windscreens & side wind deflectors that deflect the air flow wider than the oem windscreen/deflectors & preferably beyond the rider instead of collapsing in front of, or on the rider. If too much air pressure differential occurs it can create enough of a negative pressure area in front of the rider that the air collapses in on the rider pushing you forward & drawing air up the forks & directing it under the front of your helmet which can add to noise. Handguards & mirrors (anything in the airflow) also factor into the equation.

For some, the less costly & efficient use of time K.I.S.S. approach of cutting down their oem windscreen is enough...of which I did that & if all I rode was off-road within a few minutes of my home, problem mitigated (mostly), but I need improvements for extended on-road riding as well. I opted for a Skidmarx  450 mm x 4 mm thick windscreen that helps reduce flex, vibration & resonance (most aftermarket screen are 3 mm) because of its shape & width that widen the rider air envelope vs the oem (Ian @ Skidmarx custom made it for me in late 2020 after test riding several different height/shaped cardboard mock-ups & now offer it as their XL size), then cut it down by 145 mm (5.7") & mounted the cut off portion via bolt-on MRA X-Creen Touring Adjustable hardware as an adjustable height/angle spoiler blade that matches the shape/thickness of the remainder of the windscreen vs a generic aftermarket one & added a laminar flow plate of my design mounted to the oem windscreen bracket.

 

Although not a wind management component, note that the Camel ABH Support Brackets dramatically stiffen/strengthen/stabilize the entire windscreen/dash /headlight assembly, so contributes ancillary benefits, particularly when adding taller/heavier components. This is the combo for me with the oem standard height seat (now  the Seat Concepts Sport Touring Standard height seat) that provides much improved wind management for hwy riding with the spoiler raised + improved sightlines when lowered for off-road (approximately the same height as the oem windscreen) & increased air flow for hot weather riding. It allows riding with my visor up, the helmet peak no longer catches the wind blast when looking sideways, ear plugs are optional & curiously, now is less susceptible to crosswinds than the oem set up. Adjustable height windscreen brackets provide further flexibility for taller riders or if a taller seat is used. 

 

Prioritization in Terms of Effectiveness

 

If I were to prioritize each component in terms of effectiveness/impact for the T7, I would rank them as follows, with the notation that 2 & 3 are almost interchangeable depending on individual circumstances because they both can improve air flow dynamics, while 4 as a stand alone does little to improve those dynamics & just raises or lowers the windscreen sometimes creating a benefit, sometimes a detriment...it is really a combination of some or all of them that provides the most effective solutions as there is a certain amount of interrelated co-dependence:

 

1. A properly shaped/sized windscreen #1 & side deflectors #1A. They form the basis of your wind management - much like a well designed chassis sets the foundation of your handling - with the caveat that the T7's Rally inspired design with forward located & upright angle, narrow windscreen compromise aerodynamics & limit overall effectiveness. 
2. A laminar flow plate optimally positioned behind the windscreen improves air flow up the inside surface of the windscreen reducing the air pressure differential relative to the outside surface. The effectiveness of a laminar flow plate is increased if the opening, usually in the lower 1/3 or bottom of the windscreen, is an optimal size & shape and/or the windscreen is raised/moved forward a little relative to it to allow sufficient air flow up the inside of the screen...but too much airflow on the inside of the windscreen can upset the optimal/effective pressure balance range & have negative impacts...so lots of dynamics in play & every motorcycle & different combinations of windscreens/deflectors/spoilers/etc will require slightly different tweaking for optimal effectiveness.
3. An adjustable spoiler clamped or bolted to the top of the windscreen offers tuneability & depending on the type of hardware, height adjustability, & acts like a 2nd laminar flow plate by allowing air up the inside of its surface becoming an effective tuning device for most windscreens, including just an oem windscreen. 
4. Height adjustable windscreen brackets - best when combined with a laminar flow plate, otherwise they can introduce air flow issues if raised too high. Some will permit lowering the windscreen lower than the oem fixed position & may differ in adjustment range, so best to confirm if important. Note that much of the oem T7 integrated windscreen, instrumentation, headlight & accessory bar mounting assembly is resin & rubber nuts & may not be designed for the additional stress/loading of added components & height adjustment without an additional brace/support like the Camel ABH Support Brackets mentioned above.

 

If you want a visual of the air dynamics behind your windscreen tape several lengths of string to the edges of it & go for a ride at city & hwy speeds...the better the air management the straighter & more still the strings will be. Every change made has both positive & negative potential, there is no perfect solution or one size fits all because riders come in all sizes, preferences, type of riding, bike set up, needs, helmets & sensitivity/tolerances to noise, while motorcycles have differing rider triangles, rider to windscreen distances, windscreen angle, shape, size, body work interfaces & preferred aesthetics...add in Adventure motorcycle's duality of function which demand more of it's set up...it is therefore complicated with interrelated/co-dependent dynamics...understanding the dynamics/science will get you heading the right direction, trial & error will help you find what works best for you. May the 'wind' force be with you  

 

Updated Ride Review Aug 2022 after 10 day 3,800 km Trip

 

My preferred warm/hot weather, no rain set-up is with the spoiler in the low position & the windscreen set to the lowest travel of the T7 Rally adjusters, which provides the best site lines & clearance + some wind to cool my face or push the air flow over my head if I slouch slightly...for rain, colder riding & maximum coverage I prefer the spoiler in the high position.

 

      

 

     

    

 

     

 

 

Updated Ride Review April 2024

 

I removed the 2 way adjustable linkage arms for the windscreen spoiler MRA X-Creen adjustable touring hardware resulting in the spoiler being more rigidly mounted improving the effectiveness of the spoiler creating a smoother, quieter & higher airflow over my head reducing buffeting. The spoiler is still adjustable for angle, just not height. The T7 Rally Adjustable windscreen mounts provide 85 mm (3.3"} range of height adjustment. I also added rubber spacers to the lower windscreen mounts resulting in a little more rake moving the upper edge closer to me while increasing the gap at the bottom improving laminar flow.

Was thinking of doing a similar idea of  covering the gap left when the windshield is adjusted up. 

[Canzvt]

I've done this process also without success.

 

Very pleased to see you had some success. I'll be following your lead and give it a try.

 

Thanks!

[gone2seed]

Saw this thread and started wondering? 

Last 4 bikes I’ve owned had shields from Madstad engineering. Gave  them a call just now,retired, what else do I have to do for fun? 

   Sorry, they have  not got A T7 in to work with. 

If you live near by give them a call. (To damn hot to ride anyway!)

I am running a givi sport screen with motopump risers on it now. It works good till I jump on The GSA with the Madstad. 

  With it ear plugs are optional.

They are in Brooksville.

Just updated the info...see the last paragraph

[Burner]

Wow… that was A LOT of info!

 

I’m 6’ tall also with a longer torso, standard OEM seat. Short PowerBronze screen went on after one month  of ownership.  One year later, couldn’t be happier. Nice clean air, no buffeting, nice and simple! 

[jdub53]

I've also just found an add-on spoiler to be the noise/buffeting solution on my T7.

 

I'm 5' 8" tall with a 32" inseam, so have a short torso. While not excessive, the noise and buffeting from the T7's OEM windscreen has bothered me mostly because my frame of reference is my R1200GS on which I experience a quiet, smooth ride (with VStream's short screen). My T7 came with both the OEM screen and a Powerbronze short sport screen. I found the Powerbronze a bit smoother, but no quieter than the OEM unit.

 

I wear well fitting ear plugs when riding each bike and hearing aids when off of them. Very sensitive to elevated noise levels. 

 

Several months before buying my T7, I bought an inexpensive (~ $25) windscreen spoiler through Amazon for the GS just for giggles because so many people were talking about them.  The spoiler made a definite difference, and now I pop it onto the GS for longer rides involving highways (takes seconds to slip on and secure once I had the best set-up figured out).

 

  

 

I wondered how it would work on the T7, so I bought the same item and installed it this past weekend. After stopping once and making an adjustment to my initial setting, wow. Noise and buffeting are virtually gone, about 90% as quiet and smooth as the GS. During a T7 ride yesterday, I realized at one point that I hadn't even thought about noise or buffeting anymore, and to me that said it all. The best, most relaxing riding I've had since buying the T7.

 

This spoiler is staying on the T7 all the time, and I'm going to buy at least one spare spoiler to keep on the shelf in case either bike needs a replacement.

@prowlnS10 - Thank you for sharing your doctoral thesis on the subject of rider air management. 

 

Seems that none of my past 5 bikes ended up wearing their original wind screens. They all ended up with slightly larger screens to try to stay within the sweet spot of dual sport compromise. For the T7, I've recently (before reading your dissertation) ordered the AltRider adjustable mount, but it's backordered so won't know for a while if it helps. I have an adjustable windscreen mount on my Super Ténéré and it helps. After playing with it for years, I've settled into one height/angle setting for highway and drop it all the way down for dirt work. Lots of adjustability, 2 actual settings.

 

For reference, I'm 6'0" tall / 34" inseam. I ante'd up for a Tall Comfort in the Seat Concepts group buy, so I figure I would need windscreen adjustability to get back to zero with a taller seat...when it comes.

 

While I don't have personal experience, my reading on the subject leads me to favor the laminar lip concept as the single best air flow adjustment method, but I can't get past the mounting brackets being in my sightline. Maybe you just get used to it and don't see them after a while but I'm the kind of guy who pulls off the highway to clean his visor for a bug splat, so not sure I could live with those mounting brackets. Speaking of bug splats, It always amazes me how many bug splats end up on the back side of the windscreen. Wind vortexes in action!

 

Your comments about airflow under the windscreen, especially when raised, are of particular interest to me since windscreen raising is my modification of choice. You describe an adjustable "laminar plate", which by your pictures, I take to be the black "cowl" forward of the instrument cluster. If this piece is indeed the adjustable "laminar plate", I would love to get more info about it. I can see how airflow tuneability in this area could affect buffeting/noise/temperature. Something like this, not in my sightline, would be a more acceptable and otherwise complimentary solution combined with windscreen height adjustment.

 

If possible, may you please follow up on this subset of airflow management.

 

Thank you,

Boondocker:  The "adjustable" laminar flow plate would be the spoiler blade mounted near the top of the windscreen with the MRA X-Creen adjustable mounts...they allow height/position & angle changes.  The laminar flow plate mounted behind the windscreen to the mounting brackets is fixed, not adjustable...although the theory of it being adjustable would allow more tunability, but would be challenging to implement.  Because the oem windscreen mounting bracket & the windscreen are of similar angle any plate mounted to it will direct air up the inside of the windscreen...because the abs plastic I used was not curved I squeezed the top half inward before drilling the mounting holes forcing the top edge of the abs to bulge forward to more closely match the curvature of the windscreen...this helps to direct the air up the inside of the windscreen & allows more clearance at the accessory bar for GPS/Phone mounts.  The height/position/angle of the laminar flow plate is important...if too short, too far from it or angled away from it effectiveness drops off....if too tall it can impede rider sightlines (I used clear plexi on my BMW K1300GT, see pic)...I opted to size it to go to just under the accessory bar in an effort to balance function with aesthetics.  The size (w x h) of the opening at the bottom of the T7 windscreen is a limiting factor...that is why I speculate that by slightly increasing the height via adjustable brackets air flow can be increased to improve efficiency/effectiveness of air flow up the inside surface.

prowlnS10: Thanks for the follow-up on and explanation of the "laminar flow plate". Seems it will take some determined fiddling to dial it in.

 

I like to work with Kydex because I'm able to shape it. I made a surprisingly effective and cheap cowl/wind deflector for my DR650 from a plastic garbage can. But I'm sure there is hope for me yet.

Can you link the exact one you have here?  I got a similar one for my Super Tenere before I got a Madstad but it doesn’t fit the T7

Here's the one I bought and use on both my T7 and R1200GS. Because of the T7's narrow, curved shield, the spoiler's attachment arm slots don't fit all the way flush on the top of the shield but there's probably 90% engagement and the two small security screws on each arm have plenty of grip area. Did another 180 mile on/off-road ride with it the other day and it makes all the difference for me.

R & D Continues Focused on Air Entering Cockpit from the Sides

 

Mounting the windscreen to the T7 Rally Adjustable mounts w/spacers on the bottom mounts & raised about 2.54 cm or 1" combined with the laminar flow plate have improved air flow up the inside & over the top of the windscreen very well....but has increased spill over air into the cockpit on the sides & lower half of the windscreen as the gap between the Powerbronze side deflectors & Skydmarx windscreen have increased + depending on the riders height the upturned portion of the side deflectors can direct air up under the helmet.  

 

So I mocked up fill in panels  from sandwich board & integrated their shape into the side deflectors upper edge & lower side edges of the windscreen & shaped them to clear the Barkbuster handguards with  the bar risers mounted in the oem rearward position.  The shape now provides complete integrated coverage from the headlight on up & a full envelope of still air in the rider cockpit...it has even reduced the air flowing up behind the forks at the tank by about half (the spill over air must have been drawing air up from the fork area)...this is the most immersive coverage yet & if you can envision it all in plexi vs tape & sandwich board, is a shape that looks better balanced aesthetically than anything else I have seen...this is a shape that I would love to see Yamaha or other manufacturers offer as a Touring windscreen set up.  The only mod might be to add about 2-3 cm or 1-1.5" to the upper half of the windscreen to widen the air pocket on the sides of the helmet...right now I have about 1.5" side movement of my head before I hit air flow.  The challenge will be to design a mounting method for the shaped & slightly curved plexi panels that adds enough rigidity while integrating aesthetically.

If you  were to use painters Blue Tape it would look more Yamaha like.   

Is the next step to source some plexi and make it work?  I'd like to see the finished piece.  And, do you think if the new and improved version were one piece, no separate lip on top, it would work and look better?

[prowlnS10]

Good idea with the blue tape ...just used what I had in the shop...then decided to black it all out with a marker so more camouflaged while I sort out the rest of the project...now it looks a little like a real R & D project on a pre-production bike   Will get some 4 mm clear plexi to match the thickness of the Skydmarx windscreen & shape it with a heat gun...still sorting out the mounting method & allowing for height adjustability.  The windscreen was originally a custom made 450 mm Skydmarx that I cut down so that I could mount the cut off piece as an adjustable spoiler that can be lowered for off-road for improved sightlines.  I needed the 450 mm for my height, but  a shorter rider might get away with the cut down windscreen.  The spoiler does aide laminar flow, allow adjustable angles/positions & visually breaks up what was a very tall windscreen, so it serves multiple purposes.

Is your wind tunnel finished yet?

Unbelievable write up and great info.

Thank You!

My improvement to this problem, at 6'4'' in fifty years of riding i have come to the conclusion that you can only reduce wind noise.

I got a Power bronze flip screen and wind deflectors from ruggedroads.co.uk more buffeting  so i got a T7rally.com  screen extender and raised the screen that stopped the buffeting but the noise was just as bad due to the massif gap between the lower edge of the screen and the top of the headlamp unit to fill this gap i cut the OEM screen in half and used the lower half to fill this gap.

The countersunk screws that come with the screen extender are long enough to attach the part of the screen and the extender to the original holes the upper holes need a spacer to keep the screen extender level i used two small but oversized stainless nuts that the countersunk screws will fit through this allows full adjustment for the screen use thread locker on all four screws.

This shows the lower part of the OEM screen and the extender in the original holes.

This shows the small nut used as a spacer on the upper screw holes. 

This shows the size of the gap with the screen at full extension.

Gave it a one hundred mile test yesterday  no buffeting and wind noise reduced to an acceptable level.

As another 6'4 T7 rider bothered by the wind well done! I have the screen T7rally adjuster and am mulling over which extended screen to go for but hadn't thought to double up like that! Do you have the taller rally seat on the bike as well?

 

I would like to see what it looks like as an overall as my only issue with the extended aftermarket screens is I cannot find one I can bear aesthetically.

[Mapbook]

I have the standard seat fitted  it works well.

@prowlnS10 Great research and detailed information, subscribed to see what you come up with next.

 

@jdub53 Mucho thanks for the Amazon link and pics.  I took the plunge, threw $25 at that piece of plexiglass and it's almost magic! Took my head rattling ride and refined it to not too bad at all. It isn't even remotely attractive,  but put me in the happy camper column.  Vital stats: 6'1", 36" inseam, SC Tall Comfort seat.

Wow... after returning the Puig (made things much worse), I also pulled the trigger on this deflector.  Wind noise and buffeting now under control!   Very happy, in fact I think this set up with the OEM windshield , windshield extender and this deflector is actually more effective than the Madstad was on my old Gen2 KLR.   For your reference, I am long in the torso (6"3" with 32" inseam).  Thank you @prowlnS10 and @jdub53!!
