TrailMaster TM38E 300 EFI Dirtbike 31hp, 6-Speed Manual, Liquid Cooled
The TrailMaster TM38E 300 EFI is a high-performance full-size dirt bike built for serious riders who want maximum power, modern fuel injection, and race-inspired handling. Powered by a 298cc liquid-cooled EFI engine producing around 31 horsepower, this bike delivers strong acceleration, smooth throttle response, and consistent performance across all terrains.
As TrailMaster’s flagship 300cc dirt bike platform, the TM38E combines a 6-speed manual transmission, inverted suspension, and a lightweight steel frame to create a machine that feels stable at speed yet responsive in technical terrain. The EFI system improves cold starts, fuel efficiency, and overall reliability compared to carbureted models.
With its full-size motocross geometry, 21/18 wheel setup, and upgraded suspension system, the TM38E is designed for riders who want pro-level performance without stepping into premium European pricing.
