thanks for proving jumper mod gains...!"True hp" is generally 10% to 20% less than the engine's "bhp" ratings due to drivetrain losses.
Can a dyno get crankshaft power ratings? That's news to me, I didn't know that. How does it work? Certainly not through the use of the rollers, because that's wheel horsepower.i seem to be a little confused....when a bike is put on a dyno you either can get a crank reading of which this will be a higher figure...or you can get the true brake horse power at the back wheel. this would be the figure that your bike is making in real terms....this is how it is done in the UK.
if there is no such thing aa BHP then what do you call your power readings.
Actually, a dyno comes in diffent shapes and sizes. Although the one your used to seing is not capable of measuring power from the crank, there are some that do. However, these are typicly found in laboratorys, and factory testing facilities. Thats how they get true BHP numbers that the factory likes to advertise.Can a dyno get crankshaft power ratings?

Brake horsepower never applies to actual wheel horsepower, even in the UK.
