The R65 engine makes 36 bhp at the rear wheel.75/80 38; mono R100 48: R90S 50 and big valve R100 54 is the best I have seen.
I owned a BMW speed shop in the late 1980's early 90's and had dozens of customers bikes dyno tested. Even though these figures seem low the bikes are light and the power spread good.
