[quote=“Garick,post:23,topic:40084"”] something is not adding up here, swap 2 and 4 stroke in your first post? [/quote] no, there is a bit more math involed, i was just trying to set an exaple quick. 125 2stroke compares to a 250 4 stroke.as sledmire said do the math then, but you have to slit the 4 strokes overall power in half due to not getting power every stroke etc… sldemire… i live 15 mins from 51 on a farm, theres trails around here, and the main sled trail runs thru my back yard. im not at 51 at all anymore unless i watch, im 30 secs up the street at the supermoto track --- _[View the full topic](https://forums.speedlife.net/t/what-dirt-bike-to-buy/40084)._
