Yes, comparing a current state 250F bikes against the early 250F's its a whole new 14,000 rpm ballgame.
IMHO a 125 could not compete with a 250F at the pro level. Ever.
you meant ever again right? back in the early days the 125's regularly beat the 250f's
Yeh 4 bangers wernt arnt like they were. My modern CRF450 handles amazing and pulls like a train. Its all I use for racing in almost all conditions
I took out my RM250 tuesday on a very icy sandish track, 3 corners in and a kick of the smoker power had me highside off and dislocate my shoulder.
I know on the 450 it would have tracked better. I find the 250 smoker slower and more violent with its power but its great fun to ride, sounds a hoot and good fitness.
