Have you ever ridden a Gas Gas 450? Man, they are so buttery smooth! Nearly got one my self! I had heard that many times and finally experienced for myself. Smooth is correct and often attributed to it's EFI...but it doesn't feel that powerful or particularly light. Then I saw the dyno figures. "Smooth" can also be ad speak for less powerful. At 42 hp it's about 5 down a WR/ CRF-X etc. Maybe the new GG 500 will be a good way to go...with power to match it's weight.
