2012 Yamaha TT-R50E, NOW IN STOCK!!! - For the younger, smaller off-road fanatic in your family, look no further than the user-friendly TT-R50E. The 49 cubic centimeter four-stroke engine feeds power through a three-speed semi-automatic transmission, great for learning and playing.

Once they're going, you'll be glad to know, the TT-R50E is equipped with front and rear drum brakes to deliver strong, dependable stopping power. Like all Yamaha's, TT-R's are packed full of leading-edge engineering and stand up to our stringent standards for reliability. They're built to last. The only thing we can't do is stop your little ones from out growing them! But we've got their next Yamaha waiting when that happens.
