The 450s sport ATVs motors are derived from the race ready 450 motors found in motocross bike,they have high compression ratios and the short skirt high rpm pistons, its more than just about larger cc that it has over the more recreational oriented 400ex.
A CR 450 will beat a XR650 in a drag race.

Ok boys I have a 440ex with a stage 2 cam port and ploshied head with a smaller gear on the back I have not found anything that beats it on a 300 feet strip... If u can beat the 440 then the bike needs a new rider.. By the whey I have 2500 just in the motor.. Have title will travel to to take your title.... I also own a 07 rappy se the 440 wins every time..
