One of the 3 classes in Motocross
. 1. The 125 class 2. The 250 Class 3. The Open Class. Possibly the most popular class......
Basically the number means the amount of CC
that the bike i supposed to have to compete in the race. But a few years ago people decided that it was alright to race 400cc 4-stroke bikes in the 250 class against 250cc 2-stroke bikes. A 250 4-stroke has no chance against a 250 2-stroke.....so i suppose this is reasonable. The first 400cc 4-strokes did really well against the 250 2-strokes and it pretty much evened thing up (powerwise)......but then the Motocross Committee did something stupid and allowed the 4-strokes 50cc more........and now the 2-strokes are really underpowered and no one races them anymore.
So basically the 250 class is now the 450 class............They should just call it the Open Class, that way we can see a 500cc 2-stroke beat the crap out of a 450 4-stroke.
