disappointed with the horsepower

Today I got a chance to put the bike on a dynojet to see what the actual horsepower really is at the rear wheel. Drum roll .................

1st run in it was 88.95 and second run was 88.33.

I think for a 1200 cc bike this a bit low. Reading articles about the HP on the bike all say around 108, now I am guessing that is at the motor. Has anyone else put the bike on a Dyno? I am also wondering if the low HP is cause by the ECU holding back the power.

It is really to bad about the horsepower rating. Not to long ago the same problem was prevalent in boat engines. It was stopped and the horsepower is now rated at the prop.

What gear?
TC1?
TC off?
(S)?
(T)?
Is your bike 100% stock?

It's got plenty o' juice for me and my taking curves at super legal speeds...
what's not to like - it ain't no sport bike - but it gets it on.

101 (max) Crank PS at 20,000km Sports mode 5th gear TC off

Rear wheel 88-90.1 (approx) at 20,000Km Sports mode.

A 12000cc Sports motor can make lot's of power, but has tractability problems slogging it through rough terrain. Try a Ducati 1198 engine at a crawl up a rough incline.

So it's horses for courses. What YAMAHA have done is taken what works off road and applied it to a 1200cc Bike.

The nearest equivalent in the Car world would be a Patrol or Landcruiser. not an X5 or Porsche Cayenne.

I am glad they did, and also glad that other manufactures have gone for the Jacked up sports bike for those people that never go off road.

I am sure YAMAHA could move the rev range up to work between 4K and 9K like an 1198, but then it would be pretty useless off road.

Now if they did then decide to make 150HP the fan and cooling system would get stressed at low speed, so that would mean more weight.

The Rear drive would have to have even more cooling fins adding more weight.

I find the bike works really well in the real world and don't think much about the power, because it has gobs of torque where I use it all day.

All the specification / power wars have done over the years is made bikes more and more ridiculous for most people.

How many people are busting to get that 7 way traction control?

In defense of the power this bike puts out, it really doesn't matter to me "how much", but instead is just "how". I bought this unique bike for its mostly unique mission. And for me, it is splendid. If the number was 98, 108, or 128, it wouldn't have mattered to me if it did its job disappointingly. AND, the whole problem most have with the ~98 is because it is from a 1200!

That too, doesn't matter to me. It could have been 98 from a 998cc motor. As long as the bike still delivered the same experience.

I have had plenty of bikes where HP mattered. I've chased that demon for years. Thank goodness a 2002 SV650 unexpectedly delivered me my freedom! Lol (bought it for the wife. Finally had to admit it gave me a bigger grin than my GSXR)

Having said all that, I am not against improving the performance of my Super Tenere. But gaining higher output numbers on a dyno run is just not the measuring stick I would use for this one.

And finally, I personally find great comfort in the advantages of getting these modest hp numbers from a large displacement motor. It MUST be very understressed by todays standards. No wonder the rental bike with 70,000 kilometers on it ran so perfectly! Can you imagine a harder 70K? Rent miles!?

It pulled like a mule loaded 2-up maxed out climbing mountain grades at altitude. It was so gratifying to know my pampered and loved bike at home promised to be every bit as dependable. :)

Yamaha engineered this bike this way on purpose. I commend them for not losing focus and being side tracked by fear of numbers. On paper, she ain't too sexy. Weight and HP both have fooled more than a few folks.

completely true to me as well. i love this bike. horsepower would have come at either weight or build quality. i did not buy this motorcycle for it's crazy speeds, but rather for it's comfort, torque, reliability, and of course ability in most any situation i would like to get into on a road bike.

if a person wants a faster motorcycle there are tons out there in many forms. in fact the new Triumph Tiger Explorer is going to be a beast, but i feel that the reliability is best on the Yamaha. if i want a faster motorcycle i will get something different for that purpose, but i will not let go of my Tenere'.

in fact a was having a little buyer's remorse combined with seller's remorse on letting go of the Daytona. i just miss that bike for what she is. then i turned that traction control down a level and had the Tenere' in sport mode. i forgot about what that would do for the bike, and i was surprised and thrilled when i did that. i will get a sport bike again one day, but i know that this bike has more than enough power for what any of us may really need it for legally and illegally.

I don't know what gear it was in probably 5 or 6th gear.
TC was off and in sport mode.
It is also 100% stock.

I was not complaining about the performance of the bike I was just surprise about the HP is was producing. The bike pulls nicely and works very well in the dirt.

Absolute speed = Horsepower
Absolute FUN = Torque

I'll take torque over HP every time.

sounds about right - you lose around 20HP on the shaft

I have to agree with others here. I really don't care what the rear wheel HP numbers are. What matters is how that power is delivered. Off road I find it splendid. On the highway it's fast enough. This is the first bike I've ever owned I haven't dropped any coin into the engine to get more out of it. Love it!!

Yep, 88hp or what ever, works for me. Dependability is the main thing, I want to ride, not fix stuff.

I could use a few more HP as I find it slow compared to even my old V-strom 1000. But then again I own a GSX-R1000 so everything seems slow after that. My biggest pet peeve is I really don't care for the TCS default back to 1 on switch off and that I really hate!!

My s10, 2 up, is a lot faster than a tiger 800. I know that. It's also a good bit slower than a honda 919 with one rider on the honda. I want a rematch with the 919 when I'm solo. I think they would be very close.

I have to agree with you on this one. My Vee seemed to have a little more power on take off. I could twist the throttle and the front end would lift with ease but with the ST it is a little more effort. When on a trail with a log crossing it, it the Vee would go over easier by cracking the throttle and lobing the front tire over it.

What's not to like? Forget dyno numbers ... drop the hammer on a fire trail, keep the revs above 3000 rpm with TCS off, and tell me you are not grinning from ear-to-ear.

Just dont forget to brake the 600+lb beast early :p :p :p ...
