Five and a half years... 65, 000+ kilometers... and not once have I had any problems with the engine... Its a dream bike; though now that we have more designs, its design may seem a little outdated. However, the styling of Yamaha RXG-135 still remains a classic. Drive rash (Im not saying fast) and any bike would give problems and mileage would suffer. But the pick-up of Yamaha tempts you to push the throttle to the limits... No problems with that though if you keep it a single-user bike. Over all, it’s been a fantastic experience of owning and driving a Yamaha.
