TrailMaster TM38E 300 EFI Dirt Bike - 31hp, 6-Speed Manual, Liquid Cooled


Description

The TrailMaster TM38E 300 EFI is TrailMaster's first full-size fuel-injected dirt bike, built for riders who demand serious performance without compromise. Powered by a 298cc single-cylinder, 4-stroke, liquid-cooled engine with Electronic Fuel Injection, it delivers 31 horsepower and a top speed exceeding 65 MPH. The full motocross-spec ergonomics, race-tuned suspension, and 21"/18" wheel combo give it the feel of a purpose-built competition machine right out of the crate.

Designed to handle virtually any terrain, the TM38E pairs inverted hydraulic front forks with dual-adjustable rear shock and front and rear 240mm disc brakes for confident control at speed. At just 234 lbs, this bike strikes an impressive balance between power and agility, making it a compelling choice for intermediate to advanced off-road riders looking for a full-size machine with modern EFI technology.

FAQ

What is the advantage of EFI over a carbureted dirt bike?

Electronic Fuel Injection (EFI) automatically adjusts the fuel-to-air mixture based on temperature, altitude, and throttle position. This means easier cold starts, smoother throttle response, better fuel efficiency, and more consistent power delivery compared to a carburetor - especially useful when riding at varying elevations or in changing weather conditions.

Is the TM38E suitable for beginners?

The TM38E is a full-size, 31hp dirt bike with a 6-speed manual transmission and a 37" seat height. It is best suited for intermediate to advanced riders who are comfortable with a clutch and higher-performance machines. Beginners may want to start on a smaller displacement bike before stepping up to the TM38E.

Does it come assembled, or is assembly required?

The TM38E ships partially assembled in a crate. Some final assembly is typically required, such as attaching the front wheel, handlebars, and mirrors. Basic mechanical knowledge and standard tools are recommended. Always refer to the included documentation before first ride.

How is this bike shipped?

The TM38E is a large powersports vehicle and ships via freight on a pallet. Delivery is typically curbside. Contact us at service@omahasportsandgames.com before purchasing if you need a specific ETA or have questions about delivery logistics.
