I'm starting racing hare scrambles next year and the guys I ride with are "C" class. I'm as fast as them, I'm a bigger guy 6'2" 200lbs and 34 years old. I've been riding a long time, some of my previous bikes were kx250 yz250 and yz426. I'm trying to decide it I want to buy a Wr450 for hare scrambles or new yz450? My old 426 was a little too much in the woods so I put a FWW on it and then it worked great, although it was in need of a revalve. I've never ridden a newer 450 so I'm wondering if the yz will be too much power for me in the woods? Does the yamaha programmer allow you to really tame it down for riding in the woods? I'd likely put a FWW on it and revalve the suspension, maybe an EXP 2.0 rekluse as well. I like the idea of fuel injection and all the latest tech over the older WR.
