JHL MK125

The JHL MK125 is a capable 125cc-class pit bike built for riders wanting more punch than a 110cc while keeping the bike compact, simple and easy to maintain. Powered by a 123.7cc air-cooled single-cylinder 4-stroke engine, the MK125 delivers reliable off-road performance for recreational riding, paddock use, trail-style riding and pit bike tracks. With a 4-speed transmission, multi-plate oil-bath clutch, and PZ19 carburettor, the MK125 keeps the mechanical package straightforward and serviceable. It also features both electric start and kick start, giving riders convenience while still having a backup starting option. The bike is built around a steel frame and steel subframe, paired with JHL Ø33 inverted front suspension and a rear monoshock absorber. Front and rear 190mm disc brakes provide dependable stopping power, while the 250mm ground clearance, 750mm seat height, and 1130mm wheelbase give the MK125 a practical, confidence-inspiring stance for off-road use.
