difference between 2 and 4 stroke

[QUOTE="Chili, post: 1301164, member: 29892"] Inequities in the AMA rules that allowed 250 four strokes to race 125 2 strokes and 450 4 strokes to race 250 2 strokes has basically lead to the extinction of 2 strokes for racing at a National level. Combine this with an OEM agenda to push the more expenisve to purchase and maintain 4 strokes and you end up with very limited 2 stroke options. A 250F or 450F race bike is nothing like that TT-R.
