...but the ST is not the same as a Z1, KZ1000, etc. It is shaft drive. Otherwise same engine. All other parts not interchangeable. Tank, side panels, seat may look similar to KZ1000 Mark II, which is a very rare and sought after model. So about the ST...not much collector demand for these, and I don't know about you, but I never liked shaft drive much. But hey, if it floats your boat, Kawasaki builds solid stuff.
