Riders 6 years of age and older are lining up to welcome this newest addition to the Yamaha ATV-family. Yamaha has made it possible to meet the highest of young expectations with a 49cc four-stroke engine, automatic transmission, low maintenance shaft drive and push button electric start. But because safety is paramount, everything in the YFM50 has been scaled in such way as to accommodate the younger Yamaha-generation. This new model has come equipped with an automatic engine shut-off tether system for the training process.
