[QUOTE="sodhead, post: 156225, member: 21815"] I've always thought about it like this - The reason we think 4 strokes feel more torquey than two strokes is because they are generally a larger displacement when the two are compared. A 426cc four vs. a 250cc two, a 250cc four vs. a 125 two, etc. A 4 stroke generally has to be about twice the displacement of a 2 stroke to get roughly the same peak power output. Both engines will deliver their high output across a certain RPM ranges. The 2 stroke typically produces its high amount of power over a narrower range of RPM's (higher RPM's), whereas the 4 stroke can produce the higher power beginning at much lower RPM's. Like I said, we could talk about this all day but I think the only way to really understand is to ride the bikes and feel it ;) [/QUOTE]
