TrailMaster TM38EX 300 Dirt Bike - 31hp, 6-Speed Manual, Fuel Injected
Description
The TrailMaster TM38EX-300 is the brand's first full-size Fuel Injected Dual Sport Bike, built for riders who demand performance on both the trail and the road. Powered by a liquid-cooled 298cc 4-stroke single-cylinder engine producing 31 horsepower, it delivers a broad, even powerband that keeps you confident in every gear. With a top speed exceeding 65 MPH and a 6-speed manual transmission, this bike is engineered to perform at a level well above its class.
Full motocross-inspired ergonomics, a race-tuned suspension system, and 21"/18" wheels make off-road terrain feel completely natural - while street-legal features like turn signals, rearview mirrors, a license plate mount, and a digital dashboard make it road-ready straight from the factory. At just 234 lbs, this lightweight machine punches far above its weight in both power and agility.
