MX1= 250cc 2stroke-450cc 4 stroke
MX2= 125cc 2stroke-250cc 4 stroke

MX3= ?
What are the engine limits for the MX3 class?
Im a bit confused

mx3 world champs
475 plus four stroke
320 plus 2 stroke, these are approx but it gives you an idea

at the mx of nations mx3 is open cc' you can run what you like, most people run 450cc bikes

MX3 (number plate yellow)
290cc to 500cc 2-stroke / 475cc to 650cc 4-stroke

I thought someone said on here about a new 350 4 stroke class that will replace the 450? Is it a 350 2 stroke that will be allowed to compete with the 450 4/?

they are talking about changing MX1 to 350cc four strokes, and also the main class in america to 350cc four strokes,

it is only being discussed, nothing in concrete yet

what's the reasoning?

450's are to fast, reck the tracks, less powerfull bikes make for better racing,

i think they are right, a 350F would be such a cool bike to ride, 450's are scary fast, but 250f's are boring fast, (ie do not scare you enough) something in the middle would be cool
