Description
Built for riders who want serious performance without the bulk of a full-size dirt bike, the Thumpstar TSX125cc is a race-ready machine that punches far above its weight. Powered by a YX 125cc 4-stroke engine, paired with a Mikuni VM22 26mm carburetor, and pushing power through a manual 4-speed transmission, the TSX is aggressive, responsive, and tuned for the trail.
The Pipe Bomb DW2 exhaust system with a 38mm header bomb delivers a deep, punchy tone while enhancing power output across the rev range. A PSC 6 Bolt sprocket and 428 HD chain add durability where it matters most.
This model comes equipped with VS1 inverted forks (770mm, 45/48mm) in the front and a VS1 linkage U shock (adjustable 350mm) in the rear for enhanced control and absorption over rough terrain. Whether you’re racing or trail riding, the 7075 alloy rims and HSK disc brakes give you the bite and control needed to stop on a dime.
