an R1 quad will never be as fast as an actual R1 streetbike (assuming mods are equal)... thats why i have never wanted to build one, unless you were planning on running across a long, flat strip there kinda worthless, in a drag race, im pretty sure well built two strokes will eat it up, but if you run in a straight, flat line for a mile or so, R1 quad could easily hit over 100 mph assuming suspension etc. was up to the task. Congrats on the win though!
