2015 Yamaha Tt-R50e, Push button electric start and three-speed automatic transmission make this the perfect bike for learning. The TT-R50E gets the same pushbutton electric starting feature as our full line of electric-start TT-Rs. Great for learning and/or playing, complete with 49cc of four-stroke fun feeding power through a three-speed automatic-clutch transmission. Big YZ styling meets little people's stature; the seat's only 21.9 inches from the dirt. Inverted fork and Monocross rear end provide great handling. Large chain cover for maximum protection and minimal maintenance.
