"funny ..thats why all the mx bikes and sx bikes are pretty much all four stroke :)"



Take away thier displacement advantage and see where they place.



Why do just about all the Pro GNCCers ride 2 strokes?

There haven't been real men riding off road since they quit riding XLCHs. To heck with these pansy monoshock long travel suspensions. Nothing like bounding across the Mojave Desert on a BSA 650 Hornet.

My 1950 Harley Hummer 125 2-stroke is on its second piston and rings (after 3 Catalina races and several scrambles). I did freeze up the engine and break the crank once. Of course, I haven't ridden it since 1958, but the engine's was new when I put it away. So my piston and rings have lasted 50 years.

LOL thats the best post yet. I finally figured out how to make my Harley 2 strokes(1 MX250,2 Bajas) last; I quit racing them!

Like the stock pegs on the Harley Baja. Solid man.



Not at all like the factory bikes Larry Roseler raced.

Top ends on their 2 smokers maybe. The 450 thumpers are notorious for short top end lifespans. Which is the primary reason for me not owning one no matter how good the bike/atv is.

well the rules are set for 250 2 strokes and 4 stroke 450s to run in the same class, i dont think its a displacement advantage. its set like all racing .. you can probably run a 500 2 stroke versus the 990s in motogp if you still want to...i dont think there is a major power advantage just how its delivered thats all...



as for the gnccers well wasnt scott summers pretty successful on a xr650 of all things ?? anyhow i think salminen would take them all to school on any bike ...there are a few crf 450s running high in that series ...and then they all get their asses handed to them by david knight on a ktm (four stroke)....

but in maybe the WEC you see most of the winning is done on 4 strokes on the overall timing .. and i dont know what it is but the gncc us riders just dont do well for some reason and in the isde as well (starting in new zealand today i think)



but its horses for courses ..i have ridden all types and find the four stroke easier to ride at an average pace but harder to ride at 100% where the 2 stroke seems harder to ride at average pace than flat out ...
