Rear spring?

[williestreet]

Has anyone had the stock rear spring off their shock?

I am looking for spring ID, free length and spring rate.

Thanks

Have a look here and their website in general. Very impressive. I spoke with John(?) and he has a T7 and really knows his stuff. They do a video of it too on YouTube.

 

I'm doing this upgrade...

Rich, 

I was looking at this earlier today... I'm not sure if I would need it or not.. I don't do off-road and ride solo all the time. 

Weight 102 plus gear.

Are you thinking of getting it for yourself?

Yes, mainly for off road. I'm 14 stone ish, so plus riding gear takes it to possibly a 90 N/mm spring. But first I'm going to measure the rider sag (I've got the static right) just to check I need it.

 

I have bottomed out off road and cranking up the preload helped a lot but I think these guys are right. He said the rebound and compression is pretty good on the shock, so I'm just going to change the spring weight only.

 

Cheers

I will have to setup mine as well and see where I stand. 

I'm happy with the ride but I'm not very good at setting suspension up. 

Will probably end up paying for someone to do it for me

I'll stick some pics up how to set the sag. That's the base setting and important to do that first.

IIRC, it's 55mm ID x 240mm free length. There are several bikes that use this size spring so it's pretty easy to source one.

Fork springs and shock spring showed up yesterday in the BBT.

They drop shipped from Cannon Racecraft in Oklahoma.

7.4-8.8 for the shock and .64 for the forks.

   I’d called and talked with George at Suspension 101 on the 15th. and was impressed, so, what the heck, I ordered custom made springs for the first time. I’ll post up a review in ?, whenever.

having a 95nm spring fitted today. im about 100kg in full kit + carry quite a bit of weight when off on my trips.

Had a chance to test the new spring yet?

If so, did the stock shock have enough rebound adjustment?

   Thanxs Jeff

2 weeks ago, i fitted 85 nm spring from Rally Raid on my T7 and had the opportunity to test rode it!

 

I'm lightweight - 78kg without riding gear, but the upgraded spring made a very noticeable difference. I was able to get correct rear sag with only 5 preload clicks, so I have good preload reserve for luggage or pillion.

I tested the spring in some enduro trails and was able to go faster than with stock spring. And rear suspension was plusher, comfortable, better bottoming resistance etc.

 

It is a must have upgrade in my opinion!

Exactly what I found rather than the 22 out of a maximum of 24 with the standard spring (90kg weight without riding gear)

Now my bike looks like this!

Great. What tyres are they and on your other picture? 150 rear still?

I wondered if the 140 was a better choice for dirty work.

With most brands they are a substantial savings over the 150s too.

testing in progress. rear feels much better.could only get 20mm sag ,no preload. maybe should have gone for the 90nm spring but i can live with it. should be better when fully loaded with rider and camping gear. i dont think i will have to use any preload.well see. i think i have the right compression and rebound settings but more to do. i think it has shown up the front end now. rebound seems ok but i backed off the compression to 1 click.am going to have a play with the front end when i can.  onward and upward.

You might find after a few hours riding the new spring "beds in" and when you check the sag again it may need a bit winding on.

my thoughts exactly

So has anybody been able to source a rear spring from any US source given the somewhat common size?  Obviously there are plenty of UK options.

Yes, I actually prefer the K-Tech option for UK springs (exact fit / lighter weight / no adapters / dark color), but was suspecting there may be other supplier options given it's a somewhat common size as Corey mentioned earlier in the thread.  I guess the issue is that it's a  much stiffer spring rate than other applications using the same size (e.g. YZ450F) given it is obviously a heavy weight machine.  The unfortunate reality is almost everything gets sourced from China these days and we end up paying  middle men to ensure some reasonable level of quality control, customer support and false sense that we're not taking advantage of oppressed people.   Even the company I worked for was sourcing jet engine parts from China, as a means of keeping US engineers and  lawyers busy doing clean up work.
