I currently have a WR450 (2005). I really like this bike but someday I'll be in the market for a new one and I was just wondering about the YZF's for trail riding. My brother rides a YZF426 and he goes anywhere with it but he's an awesome rider. I've ridden his bike and I love the close ratio tranny while accelerating but first gear is too high for me. I'd have trouble in the tight stuff and would be stalling it all the time. Another friend just got an 02 YZF426 and he's having a lot of trouble stalling and keeping the thing upright, he's going to gear it down. I honestly don't feel the extra weight of my WR all that much while I'm riding, although I know it's a lot heavier. I really don't care about lights either. Not sure I could give up that grey button though. The YZF's are just so darn sleek and light, I love them. By just gearing them down can you achieve the lugging capabilities of the WR or do you have to change the flywheel? Don't want to ruin the top end either. Let's hear from some YZF trail riders.
