@JDMblastoise22 People under estimate xr 400's. It may be a trail bike but i stay right with 450's. I have a 96 it was the first year and i noticed its much faster than newer ones. 96 also had the highest hp. I can easily stand it up in 5th gear
@TheUberPokes you probably do. If you build any xr right nothin can keep up to it. My dad built my xr250 when i was 13 and it had a spedo and everything it did 120. No joke. And my xr80 i had was a 94 he built that and id stay next to my friends crf 230. All you really need to do is port the stock exaust cuz thats where all the restriction is and put a bigger piston in and he did some stuff to the valves i dont know what though.
@69homohater You are so full of shit no matter what upgrades he did to it not even a kx or cr 250 can go 120 and 2 strokes produces 2x the power of the 4 strokes. Kx 250's run with crf 450s .....
have any of you thought of moving up to something a little larger than 80's and 400 4 strokers, I have a Husky 400 2 and it will pull faster and harder than anything mentioned here, although i had two yz 250s's and they are animals too but 400...no brainer
@TheUberPokes dude i have a 2000 cr 80 and its nothin to a 125 i also have a crf80 compared to my cr its nothin theres no way your faster i had an xr 80 slowwww
Two strokes have twice the powet but it has to hit its power band. A four stroke has consistant power and more torque for low end up hills and good for top speed.
2 stroke is way better then any 4 strokeand that xr400 got his tail kick and thats y when racing bikes line up like in race yz125 and yz250f for like local tracks
CR 80 are friggin awesome! It smokes mg buddys xr200 all day long!

@bimmer666 Have u owned a xr400? No thought so. If you knew anything about them you could tell he wasnt on it. And the Cr got a head start.
