The YFM90R may be small in size, but it's equipped with several features found on larger Yamaha models - including double A-arm independent front suspension, drum brakes, CVT transmission and electric start.

The YFM90R balances power with a range of features to give you total peace of mind. A simple CDI plug-in adjusts engine power output to suit different riding abilities while a parking brake on the handlebar ensures that the YFM90R stays exactly where you left it. The fully automated gearbox allows junior to concentrate on the track to build confidence.
