Racing Quad?

Question

What is the fastest racing quad available in the racing industry as far as stock machines go? Just wanting to know.

Answer 1

as much as i hate to say it, for MX the Suzuki LT450 is the best out of the box. for GNCC the honda or yamaha 450.

Answer 2

I would have to say the Yamaha YZF400 it is what all the pros use. The quad looks real nice too. Also Kawasaki Kfx400 is real nice and the Suzuki LTR450. And also if you want to go over 100 mph I would get a bombardier Ds650.
