Description
Designed to elevate the standard for mid-size dirt bikes, the Thumpstar TSR 140cc is perfect for both track-ready riders and trail-blazing thrill-seekers. Powered by a YX 140cc 4-stroke engine and paired with a 4-speed manual gearbox (N1234), the TSR delivers smooth yet aggressive performance with every twist of the throttle.
It features the Molkt VM22 26mm carburetor and a Pipe Bomb DW-1 38mm exhaust, giving it a sharp powerband and that signature Thumpstar growl. Built on a responsive chassis, it’s fitted with premium VS1 inverted forks and a linkage-style VS1 adjustable U shock, which handles impact like a champ.
Stopping power comes from HSK hydraulic disc brakes with a dual-piston front and single-piston rear configuration, ensuring control at any speed. The 7075 alloy rims are race-ready, tough, and outfitted with grippy tires for all-terrain traction.
