6. Honda 250R --------------------------> 31srwhp / 329lbs = 0.0942 horsepower per pound

A 250R weighs in at 291lbs. I assume they mean the TRX but I thought the TRX actually weighed more than 329. Edit: and HOJ states the hp at 39 but I don't know what srw stands for. Different measurement technique?

[03 ORANGE SHEE]

i noticed that too .has to be the trx , too bad they didnt do the atc 250r, as well as the tri-z and t-3, heck, it would be nice to have every one made on the chart

[Dammit!]

Do you know if that weight is right for a TRX? I'm impressed if that's all they weigh.

And any idea on the descrepency between these hp numbers and Hondas?

[03 ORANGE SHEE]

i dont know, billy or tim sr. should know, some numbers are high, but alot are low, i have noticed they all are within 3-4 hp from what the factory states, but the r, i know the first year zilla (87) has 53-55hp, and the later years are 51-53 hp, the intake track is larger that year (87) ..hate to feel the rush of that powerwheels thingy!!!

I'm wondering where the yfz450 stands against the others.

IDK, from my experience I'd say it's not the first two.

Those are probably rear wheel horse power numbers measured on a dyno where as Honda gave out the engine horsepower numbers.

[250RNUT]

Man, I was hoping the ds650 was better than that.I am looking to buy one of those.

[BIGCRIP28]

350x with cobra has 23 at rear wheel and it weighs 320

23/320=.071875

[Dammit!]

If you use HOJ's specs the R is ahead of the 'zilla. If you use 31 hp instead it's in second place. Not sure the specs on the other water pumpers.

39hp: 0.1340
31hp: 0.1065

[AZ250R]

Me thinks... srw = Stock Rear Wheel.
Yah I think the TRX's are almost that light, cause they sure dune like no other!

[Mr. Sandman]

The hp listed in the chart is either for an 83/84 R or it's listed incorrectly. All stock
85-89 water pumper R's have the same approximate 39hp whether they're an ATC or TRX (same motor).

[Wickedfinger]

Thats been around forever .... alot of it isn't spot on correct. For example: the 350X only having 21hp - the factory manual states 28hp. Even if you were to take away shaft hp to rear wheel - you wouldn't loose that much unless the brake was on. Now as for the DS650 goes - Rotax claims 48hp on the motor, the chart only lists 39hp - to loose 9 horsepower from just a 90 direction change is just plain absurd - thats nearly a 20% power loss.

Those are probably rear wheel horse power numbers measured on a dyno where as Honda gave out the engine horsepower numbers.

Thats what SRWHP stands for ....... Stock, Rear Wheel Horsepower.
