I have owned a yz426f for a bout 3 years and recently got a rm 125(2stroke) I really do enjoy this bike. Its fast and light. For you Cdn's out there, I moved from Edmonton Alberta to NB. The riding is very different out there and notice myself riding lots more with the 125 because of tracks out here. My question is... I'm about to buy a new bike, I'm looking at the 2014 yz250f and the yz450f. Has anyone downgraded before from a 450f to a 250f, and did you regret that decision? I have never owned a 250f before and I don't want to invest in 10G's if I'm not going to enjoy it as much. I don't really want this topic to be about what color bike I want, but more of a regret losing power to lighter bike ratio.
