This is a very reliable Dyno done by an excellent performance shop in Seattle, I am quite happy with it. The Busa is stock....for comparison many other Busas have gotten in the 150s stock on the same Dyno. 05's kick arse.

they have not done anything to the engine of the Busa since it was 1st made back in 99...Why would your bike be making 15 HP more then most other bikes stock? I know all bikes are different, but not 15 HP different...
