TrailMaster SX150 Pro Series Dirt Bike - Electric Start, 4-Speed Manual, Dual Disc Brakes

Description

The TrailMaster SX150 Pro Series is a mid-size performance dirt bike built through a collaboration between TrailMaster and JHL Offroad, engineered for riders who demand serious capability without sacrificing reliability. Powered by a Zhongshen 140cc single-cylinder, 4-stroke oil-cooled engine producing 6.8 horsepower, this bike is ready to tackle trails, tracks, and everything in between. Dual-start convenience comes standard - choose between electric start for quick ignition or kick start as a reliable backup. A 4-speed manual transmission with non-circulate gear shifting puts full control in your hands, while front and rear disc brakes deliver confident stopping power in all conditions.

Designed for performance from the ground up, the SX150 features a high-performance inverted front fork, a nitrogen air-gas rear shock absorber with aluminum linkage, and a newly innovated frame for a smoother, more composed ride feel. The aftermarket Nibbi PE22 performance carburetor ensures optimal fuel delivery, and the 19" front and 16" rear Yuanxin tires paired with reinforced alloy rims give you the traction and durability to keep pushing. Available in Red, Blue, and Green, this bike is as sharp looking as it is capable.
