    Default Top Speed

    I was told that the Gen 2 Hayabusas top out at 186MPH......How fast can a stock Gen 2 Busa go when the Restricter/ECM is bypassed? (Stock Busa)

    My experience with stock gearing and tires is 195-196ish in a perfect world.

    Read his thread that he has a link to in his signature. He tried the first time STOCK, then started changing stuff.

    Part of going fast is remembering that at some point you have to slow down

    Are talking stock as in stock exh. and all or just stock engine with bolt ons. I did most of what brock did on his bike and his did 202.3 and mine did 202.7. I did have to go down 1 tooth on the rear sense i was hitting the rev limiter at 201. I also weigh with leather about 210.
    218.71 and still rising

    Sorry! After reading my post, I think my tone came across the wrong way. I was just trying to help the people that may not have seen his thread that link. It was informative for me.

    The 182 is stock 1-mile accel only...

    Unrestricted with zero mods, the fastest I could muster was 190 GPS with my bike on a longer road fighting wind. I'm not exactly a jockey so my results could have changed with better weather (or a smaller rider). The stock gearing was only good for mid 190's bumping the limiter in 6th.

    There is no doubt in my mind that 200mph is NOT possible on a 100% stock unrestricted Gen-II bike though...
