He kills any bike that steps up to him just for bragging etc. I want to get the same done to my '10 S1K so that I can continue riding daily on the street. Do any of you know what I can do and who is best to work on the BMW since its not the mainstream of bikes?
For one, how do you really know it makes 235 HP? It takes a HC 1441 with high quality headwork and the supporting exhaust/fuel system AND a happy dyno to make 235 wHP on motor alone.
and two (on motor alone), it takes a lot more money to move a S1Krr into that range of power than a Busa. However, on spray it doesn't. Last night I tuned a Busa on spray that made 211 wHP. It had a completely stock motor and all the owner did was add a 45 HP dry shot using good fuel (C16). You could easily add a 50 HP shot to a bolt on S1Krr and be in the 235 range.
But three, HP isn't everything. A Busa is heavy, a S1Krr isn't. You won't need as much HP to beat him. But you will have to do something about the lifting the front.
