    CP2. The wonderful engine that powers the Yamaha Ténéré 700-T7


    Cruizin

    Back in 2014, Yamaha launched the MT-07 in Europe, Australia and Canada. The bike was eventually released in the USA as the FZ-07 in June of the same year. I was so taken aback by this bike that I created fz07.org as the first forum for FZ-07 owners in May of 2014. As soon as the bike was announced later that month, people joined the forum just to ask if that stunning looking bike was as good as it looked. It didn't take long for the answer to come from new owners as a resounding yes. 

     

     

    The CP2 engine 

    Star of the show was the wonderful CP-2 engine. The CP2 is a 689CC, DOHC Parallel Twin engine. Like the R-1 and Super Tenere, it employs a cross plane concept  270º crank that staggers power pulses. The way this works is that cylinder one fires at zero degrees and Cylinder two at 270 degrees, and then the crank actually spins 500 degrees before firing the next power pulse. Rinse and repeat. 

    This produces a more torquey feel and sound than your typical 180 degree layout engine. And the sound is pure bliss. 

    Bore x stroke is at 80.0 mm x 68.6 mm and Compression ratio comes in at 11.5:1 . I do wonder if Yamaha will tweak the Bore and Stroke for the Ténéré 700 version of this engine, though it doesn't need anymore power.

    The engine runs on 86 octane fuel and is easily capable of 58 MPG/4.9 Litres per 100 kilometres, just ask anyone on FZ07.org. Oil changes are spread out over 4000 miles and the Valves don't need to be checked until the 26,600 mile/42.808 Kilometer mark.

    The Next AMA Motocross champion will win on a 450 factory race bike that makes less power than the Ténéré 700.  70 HP is plenty for those of us who will ride the big three. (commute, highway and dirt).  

    Power. The CP2 is not a race bike engine. It is built to handle everyday riding conditions, it excels in both urban commuting at 2000 rpm with out chugging, and at 5000 RPM on the Freeway at ease.  Things do get a bit buzzy on the MT-07 at the footpegs above 6500 RPM, but this may be worked out on the Tenere 700. IT is also a lot less buzzy than any dirt bike at that range. 

    Horsepower is Claimed by Yamaha to be at 75 HP.  Our in house expert tuner is Nels Bysdorf at 2wheeldynoworks in Kirkland, Washington. Nels has tuned hundreds if not thousands of MT-07's and he has found that the stock CP2 engine on the MT-07 makes between 67-68 HP at the wheel.  When uncorked with a free flowing exhaust and a custom tune by Nels, the same engine makes between 71-74 HP. 

    Stock Torque is around 46 lbs and can be tuned up to around 50-51. 

    Below is a Dyno chart using MT-07 stock exhaust on the CP2 showing numbers before and after ECU flash.

    Stock engine, stock mt07 exhaust  HP and Torque, vs flashed ECU dyno chart. 

    Starbucks highway ADV guys will snub their noses at any bike with sub 100 hp numbers. And they probably should look more at the Africa Twin or new 790 KTM or even bigger bikes. The T-7 may not be for them and their road trips of glory. 

    But for those of us who take our bikes on the highway just to get to our favorite trails and dirt roads, this engine fits the bill perfectly. The availability of torque in the lower RPM range is just what is needed in an off road or dirt road bike. This engine makes gobs of it in the lower ranges. You can put this bike in 2nd or third gear and lug it up hills at 2000 rpm all day long, if you choose. I'm famous for running around downtown at 2000 rpm in 3rd gear with smooth and useable power galore. I'm not so sure that the KTM 790 will be able to do that. 

    The Next AMA Motocross champion will win on a 450 factory race bike that makes less power than the Ténéré 700.  70 HP is plenty for those of us who will ride the big three. (commute, highway and dirt).  

    Reliability?  We have over 8000 members on the FZ07.org forum and we have heard of ZERO engine failures. Zero. Zilch.  This engine goes and goes. Highest mileage I have seen so far is 66,000 and the guy hadn't even checked his valves yet. And while the KTM 790 may be just as reliable, we don't know that yet because the engine has not been around that long.  The CP2 engine is already proven to be ultra reliable, easy to maintain and dependable.  Three things not always associated with KTM road bikes.

    But if all of the above isn't good enough for a true dual sport bike from Yamaha, this engine is also slim. It fits into the frame extremely well, which means you can easily get a foot or two down on rough uneven terrain. This is so important for those with short inseam when trying to stay upright on switchbacks and atv trails. 

    The CP2 is the perfect engine for a bike that will be taken off road and ridden to and from work, to the store and yes, even on trips across the country.  This bike will be a success and I predict that it will compete every well against or even better than the KTM 790 in off road conditions.

    I ride KTM dirt bikes, have for years. But Yamaha has been getting my streetbike money since the early 80's and they will be getting my money for this true dual sport Tenere 700 with the CP2 engine. I just know that motor too well to choose anything else.

    Starbucks ADV highway warriors can feel free to dismiss my thoughts below.
