I'm looking to buy a used Yamaha 426/450 and want advice. I'm dual sporting this bike just to be street legal, but it'll be primarily a dirt bike. Comparing WR and YZ's tranmissions. Is there really that much difference. I'm sure they'll both pull my big arse around. I don't ride like a flying demon. I'll be scrambling pipelines and woods. Looked at lots of bikes so far, and found a nice 01 YZ426F already all fixed up for 3K. What I want to know, is a WR that much different that I should hold out for one over a nice YZ? The amount of YZ's to WR's for sale is about 5 to 1, so there's not that many WR's in my area to look at.
