I wanna know what is the biggest and baddest bike youve been on. What kind of bike it was, engine size, what mods it had, how fast you think it was. Just give the info. I would have to say that the baddest bike I've ever been on was a 85 Honda 250R, 330cc engine, alcohal Injected, NOS, a real dragged out bike, i was told it would top 110+ mph easy. I was only 13 when i rode it, so i didn't try takin it up that high, i doubt i would have been able to hold on to it.
