New for 2025 is the TC 300. Designed to deliver next level motocross performance, the all-new machine is powered by an easy-to-ride, fuel-injected, and powerful 2-stroke engine. An electric starter ensures easy starting, with a 5-speed Pankl gearbox offering smooth and positive gear changes. For an unrivalled riding experience, the combination of the perfectly balanced chromium molybdenum frame and WP suspension provide class-leading handling and comfort. The new TC 300 is finished with ergonomic bodywork for unrestricted rider movement with the graphics applied using in-mold technology for a durable finish.
Engine
The fuel-injected, 300 cc engine offers the best combination of unrivalled peak power and usable torque. Lightweight in construction, the engine design centralises mass, which plays a vital role in the handling and agility of the new machine. An electronic exhaust control system tailors the power in every gear to ensure maximum performance on every part of the race track. The new TC 300 57hp engine is easy to maintain, with clear markings on the engine covers indicating where to check the gearbox oil level, as well as where to drain the coolant from.
Cylinder
With Electronic Fuel Injection (EFI) as standard on the TC 300, the traditional powervalve is replaced with an electronic exhaust control system. This highly innovative technology manages the opening of the lateral exhaust ports before the main exhaust ports open to deliver strong, controllable power. The upper contour of the exhaust port features a machined finish for improved port timing and unrivalled performance.
Crankshaft
The crankshaft is designed with weight reduction in mind to increase throttle response. The perfect balance of rotating masses is achieved by balancing the weights of the crankshaft flywheel, the rotor, and the counter balancer shaft.
Functional bodywork
The bodywork has been designed to allow riders to perform at their very best for extended periods of time. Following countless hours of testing and refinements, large contact points and surfaces in the rider triangle enhance comfort, which in turn helps to reduce fatigue. A tall and flat seat offers unrestricted movement with a high grip cover ensuring riders stay firmly in place under hard acceleration.
Airbox
A strong, one-piece airbox design with an optimised air intake reduces air deformation, ensuring an unrestricted flow of air and maximum filter protection. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance.
Hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. With this hydraulic system, free play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race-focused testing have proven the exceptional reliability of the high-quality, Italian-made Brembo hydraulic systems.
Wheels and tyres
Assembled with CNC-machined hubs, lightweight spokes, and strong, black-anodised alloy rims by D.I.D, the wheels of the TC 300 offer strength and minimal unsprung weight. New, Dunlop Geomax MX34 Motocross tyres are fitted and feature a proven block-within-a-block design for enhanced control and superior grip on a variety of riding surfaces.
Exhaust system
The header pipe on the TC 300 is designed using innovative 3D modelling. The result is a perfect shape designed to deliver optimum performance across the rev-range while also being very compact to ensure sufficient clearance through deep ruts.
Cooling system
Manufactured from high-strength aluminium, the radiators are designed using computational fluid dynamics (CFD) to channel air through them in the most effective way. A large centre tube through the frame reduces pressure at this point in the system for a consistent coolant flow while an internal thermostat further enhances reliability.
