    Pure stock around 75-79 mph. With taller gears bigger tires and a pie any 450+ cc sport quad should be in the 90 too 100 mph range.

    90-100 is a bit much. Your rear sprocket would look like a bicycle wheel. it would put my LTR up against one anyday. Mine ran 74 w/ a 13t front sprocket and 18s. Ive not rode one yet but you gotta have enough motor to pull speeds like 90-100 or give it a 2 mile straight stretch w/ a small down grade

    I know a DS650 with just a slip on exhaust; 22 inch rear tires and tall gears (17/38?) will due around 100 mph. A 450 with the same set up should be able to hit 90 mph. This is a desert race setup and a HC piston; heavy duty valve spring and a new CDI may be need.

    Bone stock 525exc will pull like 102, but that is with a 6th gear and less weight. I would guess high 80's stock. Who needs to go that fast anyway?

    yeah, the 2 wheeler. Pretty much same motor, just less 6th gear.
