mx1, mx2, mx3

[Buddy L]

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

[scott411]

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

[FlangMasterJ]

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

i think ur an MX4 cam hehe :baby:

[cheese]

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/?

[scott411]

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?

[scott411]

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

[GR81]

500cc 2t? ;)

[Buddy L]

125 2t is scary enough:crazy:

That was the excuse they used to go from 500cc 2 strokes to 450cc 4 strokes/250cc 2 strokes.

Ive never ridden a modern 500cc 2 stroke how fast are they compared to a 450cc 4 stroke?? I can only imagine considering how fast a ktm 360 is.

[NordieBoy]

They would be slower around the same track.

Just like some tracks the 250 4st's are faster than the 450's.

Yeah true that but i mean in a drag race along a beach or something, I bet they are a handful.

[cheese]

well the old CR500's were something like 70hp at the wheel.

[scott411]

having owned 2 KX500's and raced them to some sucess, they are the meanist beast ever, a new 450F does not have the grunt of the 500 2t, however they are faster in nearly every circumstance that involves a corner,

the last 500 i s had was an 02 KX500, i got it just as the CRF450's came out, i took it to ardmore and had just finished practice, i was lying on sitting on the back of my ute when a guy came up to me and asked if i rode this thing, he asked what year it was as it looked like a early 90's bike (the kx500 never did change mauch form 1989) he could not beleive how fast it was, and was very pissed off with his local honda dealer who had sold him on teh fact that the CRF450 was the fastest mx bike you could by at the time, and then this thing that looked 10 years old had just out accelerated him off a jump like he was bolted to the ground, dam motorcycle saleman will do anything to sell you a bike aye ;)


the thing was a handlfull to ride, it did not like stopping or turning, but with the right soil and a bit of traction, i could ride it pretty dam quick for about 10 minutes,
