I've been through the archives and know all the physical differences between the WR & YZ. My question is for those that have ridden both...Is the weight diffence between the bikes noticable once you're rolling? Is there a noticable handling difference between the bikes? Do you REALLY need the seat/tank combo...I mean is it really that big a deal to a spode like me? I have ridden a two YZ, a '98 400 with full exhaust and a mostly stock '01 with heavy flywheel added. Both felt nimble & and carrried the weight quite low compared to my '96 Husaberg. I can get a new '01 WR or YZF for the same price but have never ridden the WR. All the WR stuff is important to me and would eventually go on the YZ, like kickstand, flywheel weight, lights. I just don't want to take a step backward in weight from my Husaberg. I'm 6'1", 200 lbs, play ride mostly woods.
