XTZ750 1989 on, 749cc w/c DOHC twin 70hp 115mph 50mpg 440lb Horrible looking trail bike with interesting ten valve, vertical twin engine, though its 360 degree crank is out of the ark and the gearchange’s poor. Wheelie merchants ruin the clutch, engine’s generally tough, though prone to an increase in roughness at high miles. Rusted exh ruins the carburation, combined with transmission wear leads to a bronco ride.
