I know this is a 4 stroke thread but need to know quick ;)! :2strokes:




Quick ? where does the RX warrior class at a sancitoned race

Thanks Andy ;)!
 

I thought only the nytro was moved up to 700 and the apex was 600 triple pipe and I think rx1 and apex are the same hp. So it should be with 600s
 
Heard the nytro runs in ths 600 single pipe class and the apex got bumped back to the 700. My guess is because the nytro weighs much less and the motors are close to the same cc with the nytro a 3 cyl 1049 and the apex a 4 cyl 998
