I just rode my new CRF today, i've been riding a 426 for a year and a half and I can tell you the CRF is the new standard for motocross thumpers. The power is an insignificant factor, most people can't use all the 426's horses anyway, but for those who must know,yes the CRF is noticably a little faster on the track. The big thing for me was the feel of the bike and the handling. The big-bike feel you get from a 426 is gone, the CRF feels like a 250 size wise. The bike is nimble and noticably lighter, and it doesn't turn slow like the 426. Your corner speed wil definetely benefit from the CRF. The suspension is awesome, my bone stock CRF is twice as good as my pro-action 426. Bottom line- All the hype is for real, this bike is for real.
