This is the original Kawasaki W1 (650cc) parallel twin. Kawasaki claims that this bike was the inspiration for the W650 I have. Just looking at the engine cases you can tell that this isn’t true. The original was heavily based on a BSA engine. The W650 engine is an interesting looking engine. Triumph Bonneville on one side.. Ducati on the other? The bevel drive cam timing is unique and unlike anything on this ancestor. It’s cool to see an original bike though. They’re super rare at this point in the game.
