I run knobbies most of the time, but I have a Bridgestone Trailwing that came off a new DRZ 400 on the 18" right now, from a trip I took in Sept.
I do recall having fittment issues with the 650 rotor on the 350 hub but can;t remember what I did. The bolts aren't the same and I ended up doing something different. Like flipping the rotor over or something. really can't remeber, but it was solveable maybe someone can remember what they did.
I was lucky to get my 350 wheel with an axle, chain adjusters, sprocket hub and cushions and a new 41 tooth sprocket for $75.
Thanks Guys. I will keep searching for the dr350 wheel. I was hoping to pick up a donor RM bike and use the front end and both wheels. I have found more than a few complete bikes that need top ends for under $500. Anyway thanks for the help.
