Description
The Thumpstar TSX 140cc is a power-packed pit bike built for thrill-seekers who want full control with maximum reliability. Driven by a high-performance YX 140cc 4-stroke engine, and paired with a manual 4-speed transmission (N1234), this unit is tuned for trail domination and race-level agility.
At its core is a Pipe Bomb DW2 exhaust system with a 38mm header bomb, delivering punchy power and throaty sound. This engine pairs perfectly with a PE 22mm carburetor, responsive throttle, and durable 428 HD chain with a PSC 6 bolt sprocket setup.
Handling is elite thanks to the VS1 suspension system: inverted 770mm forks up front, and an adjustable 350mm linkage U shock in the rear. Add in RZ dual piston front brakes and HSK rear disc brakes, and you get crisp, confident stopping power to match the ride.
Whether you’re launching jumps or tearing through trails, 7075 alloy rims with stainless spokes, a 35” seat height, and a 55mph top speed make this one of the most complete 140cc bikes on the market.
