Interesting build thread. A guy near me did a RZ350 build using all the running gear from a Triumph 675R. Rear swingarm, front forks and triple clamps, wheels brakes and all.
I used to own an RZ350, one of the greatest small bikes I've owned. When I rip down to the street on a 2 cylinder 2 stroke, everyone would hurt their neck trying to see WTF is rolling down the road.
