what two stroke 80 or 85 is the fastest? i am looking for a fast 80 or 85 for motocross.

The CR 80 or yz85 are problably the fastest aside from the KTM. The RM and KX have a powervalve, and while still fast, are better suited for beginner riders.

actully the cr and the yz are the ones with powervalves, the kx and rm do not have power valves and are better suited for beginers, I was going to get an sx85 but they had suvere transmission problems and one u bought the bike the engine had to be shipped to Austria for reapair.

Actually, not. The cr85's and yz85's DO NOT have powervalves. I had a cr, and a friend had a yz. They are almost equal. I liked them A LOT more then the rm85 I rode. None are much friendlier then the other IMO, but the yz 85 has the most kick. I havent ridden the sx, sooo I cant speak about that, but heard it was one bad mama jamma!

no the kx and rm do have the powervalve. the powervalve smoothes out the power and thats why its easier to ride. the cr and yz's dont have them and they have a super hard hit

. . . or you can buy the feather-light '05 YZ125 and have the suspension . . . .

Why would you want the fastest bike for mx? Wouldnt you want the quikest? If you really want the fastest i would try the yz or cr but if you want the quikest i would try the rm or kx.
