BMW is bad about releasing HP numbers that are at the crank.


ALL the manufacturers are bad that way. What sets BMW apart from everyone else is they seem to loose more power between the crank and the rear wheel than most other bikes. It's typical to loose 10-15% of the crank horsepower to drivetrain losses, but BMW's seem to loose 20%.


Probably due to shaft drive rather than chain.

Except BMW is not the only company with shaft drive, and their F650's (belt drive) have been just as optimistic.
