TC 125

The TC 125 receives multiple technical upgrades for 2025 to maintain its position at the head of the highly competitive 125 cc class. Updated bodywork and ergonomics offer riders improved ease of movement on the motorcycle while its lighter chromium molybdenum frame, updated WP suspension, and revised rear shock linkage ensure improved comfort and cornering. Light and strong wheels, which are assembled using D.I.D rims, are fitted with race-tested Dunlop MX34 tires for stability and improved traction. Premium ProTaper handlebars offer a confidence-inspiring steering feel. For 2025, the TC 125 is completed with stunning white and blue graphics that are applied using in-mold technology for a long-lasting finish.


 

Engine
The TC 125 engine sets the standard for performance in the highly competitive 125 cc class and weighs in at just 39.46 lb (17.9 kg). The lightweight engine is manufactured using the latest engineering techniques to produce more torque while retaining its high-revving 2-stroke character. With the rotating mass inside the engine centralized, the TC 125 offers light and agile handling to the benefit of both beginners and professional racers.
Cylinder
The cylinder features a 54 mm bore and an innovative electronic exhaust control system. Using an actuator, the lateral exhaust port and main exhaust port open simultaneously for maximum power delivery.
Crankshaft
The lightweight crankshaft improves throttle response and reduces vibration to a minimum. The component is precisely positioned to ensure rotational mass has very little effect on the overall handling of the motorcycle.
Crankcases
High-pressure die cast production processes allow for the crankcases to be manufactured with a thinner wall thickness to keep the overall weight to a minimum and optimise mass centralisation. Symmetrical engine mounts aid handling by contributing to the flex characteristics of the chassis. Internally all engine components are positioned to achieve an ideal centre of gravity.
Gearbox
The 6-speed gearbox is manufactured exclusively by Pankl Racing Systems and ensures the highest level of durability and reliability. The shift drum and shift fork improves overall leverage for significantly smoother and more precise shifting. A special gear lever tip design prevents dirt build-up for positive gear changes in all conditions.
DS Clutch
The diaphragm steel (DS) clutch fitted to the TC 125 features a unique design where a single diaphragm steel pressure plate is used instead of traditional coil springs. Housed inside a CNC machined steel basket, the overall clutch design is highly durable and contributes to the compact layout of the engine.
