TrailMaster TM29 125cc Dirt Bike - Large Frame, 4-Speed Manual, Electric Start (17/14)

Description

The TrailMaster TM29 is a serious 125cc dirt bike built for riders ages 12 and up who are ready for full motocross performance on a larger, more capable platform. Powered by a high-performance 125cc single-cylinder, 4-stroke engine producing 8.3hp, this bike delivers a top speed of around 55 MPH with the kind of broad, even power band that inspires confidence on every ride. The heavy-duty twin-girder steel frame stretches 70 inches long - noticeably bigger than the TM24 - giving taller and more experienced young riders the room and stability they need.

Dual-start convenience means you get both an electric start and a kick start, so you're never stranded when it matters most. Full motocross ergonomics, inverted front forks, and a race-tuned suspension system let the TM29 handle trail obstacles, jumps, and rough terrain naturally and with precision. Front and rear hydraulic disc brakes bring serious stopping power to match the bike's performance credentials.
