The Latest Trailmaster Dirt Bikes - C40, C50, and C60

Explore the newest additions to our collection from Trailmaster: the C40, C50, and C60 models. Over the past five years, Trailmaster has meticulously built an exceptional dirt bike line, earning its reputation as the go-to manufacturer for recreational bikes.

The latest release is the TM C50, featuring a powerful 145cc ZM Single Cylinder, a 4-stroke air-cooled 6.8 HP engine. Built on a twin-spar frame with a dedicated focus on quality construction and harmonized components, Trailmaster establishes itself as a leader in the dirt bike market.

The true measure of a dirt bike's quality lies in the tolerances employed during construction. With Motobuys in business since 1989, we can discern when a company is committed to creating a product designed for longevity.

  • Powerful 4-stroke oil-cooled 145cc, 6.8 HP engine
