I've had a 73 Interstate and currently have the 75 Roadster ... for a few extra kgs. I like the starter and the motor / gearbox layout is definitely better (and did blow a layshaft bearing on the 73 gearbox) but the decider was the LH shift 'cos I'm not mentally agile enough to change LH / RH gear changes from bike to bike. Even sold the TR6 for that reason.
