TC 300 | 2025

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.


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.


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.


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.

Counter balancer shaft

The TC 300 features an innovative laterally mounted counter balancer shaft. This shaft significantly reduces engine vibration, resulting in a smoother and more comfortable ride.

DDS clutch

The damped diaphragm steel (DDS) clutch fitted to the TC 300 is unique as a single diaphragm steel pressure plate is utilised instead of traditional coil springs. Housed inside a CNC machined steel basket, the overall clutch design contributes to the compact engine layout and features a damping system for improved traction and durability.


The TC 300 features a 5-speed gearbox manufactured exclusively by Pankl Racing Systems for the highest level of durability and ensures smooth and precise shifting. In addition, the gear lever tip design offers improved leverage and prevents dirt build-up, even in the toughest conditions.

Adjustable ergonomics

To accommodate youngsters of different sizes, the TC 50 offers multiple adjustment options to suit a wider range of riders, based on their height and set-up preference. The handlebars can be mounted in four different positions, the rear shock can be positioned from standard high position into a lower setting, and the subframe and bodywork can be installed in two different places to suit each individual rider.


The frame of the TC 50 is made from chromium molybdenum steel and enhances the riding experience thanks to its precise geometry and calculated flex. Utilising a proven design concept, the shock is not connected to the upper frame tube to reduce the energy transferred through the chassis, which leads to greater stability. Frame protectors with a textured surface enhance control in all conditions and protects the dark blue metallic powder coating from wear.

WP forks

Featuring the latest in suspension technology, the TC 50 is equipped with 35 mm WP XACT-USD forks. Besides being very lightweight, the forks offer exceptional damping and comfort, which allows for youngsters to ride with complete confidence. Offering 205 mm of wheel travel, the air spring in the left fork leg can be easily adjusted using the supplied air pump to create the perfect set up for any rider.

Functional bodywork


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.

Hydraulic brakes

The highest level of quality is guaranteed as the class leading Brembo brake calipers are made from single-piece aluminium for exceptional strength at the lowest possible weight. Together with a 260 mm front and a 220 mm rear disc, which are designed to prevent mud build-up, superior stopping power and braking confidence is guaranteed in all conditions. A strong rear brake pedal offers exceptional durability for continued braking performance.

ProTaper handlebar

Developed between Husqvarna Motorcycles and leading handlebar manufacturer, ProTaper, the exclusive bend offers superior comfort, class-leading strength, and fatigue resistance at the lowest possible weight.

ODI grips

ODI lock-on grips feature an innovative, integrated throttle mechanism and are installed without using glue. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalised throttle action.


The CFD-designed footrests are extra wide to ensure better control of the machine while at the same time are less susceptible to catching on deep ruts, take-offs when scrubbing, and trackside barriers. This is achieved by a narrower mounting design in the frame layout, which also helps reduce overall weight.

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.

Fuel tank

A 7.2 litre fuel tank integrates neatly with the ergonomic bodywork and features a durable rubber cushion beneath it to protect against wear from the frame. The one-piece fuel pump and integrated filter allows the tank to be emptied further to offer an extended running time. For reliability, the external fuel line is specifically routed to make it less exposed and susceptible to damage.


The electronic fuel injection system on the TC 300 brings many benefits. The ECU from Vitesco constantly analyses the running condition of the engine and delivers the perfect air/fuel ratio at all times through the state-of-the-art 39 mm Keihin throttle body. EFI also introduces two different engine maps, which can easily be activated via the handlebar-mounted switch for a personalised riding experience. Map 1 is backlighted in white, while Map 2 is backlighted in green. Additionally, a redesigned reed valve system improves intake tract sealing and prevents excess fuel building up, which would lead to rich running of the engine in extreme up or downhill sections.


For guaranteed, easy starting in all conditions, the TC 300 features highly reliable electric start technology with the system removing the need for a kickstart completely. The 12.8V 2 Ah Lithium-Ion battery is positioned neatly under the seat and close to the centre of gravity for uncompromised handling. Stopping of the engine is achieved via the same handlebar-mounted switch for improved ease of use and a simplified operation.

Map switch

The electronic fuel injection (EFI) on the TC 300 allows for the introduction of two engine maps that cater for riders of all abilities. Map 1 (white) is the standard option and delivers linear, predictable power, while Map 2 (green) is more aggressive with a quicker throttle response and a sharper, more explosive power output. By simply pressing a button on the handlebar-mounted Map Select Switch, riders can toggle between the two options and select their chosen map.


The engine management system (EMS) is designed to be small, light, and fast at processing data. It incorporates a Rollover Sensor (ROS) that cuts the ignition and shuts off the engine in the event of a severe crash for an additional layer of safety.

Hour meter

The hour meter comes with an integrated fuel level indicator, which is visible on the FI status LED, and warns the rider when the fuel level is getting too low.

Start/stop switch

The combined engine start/stop switch is located on the right side of the handlebar for easy, thumb-operated use. Not only simplifying the starting and stopping of the engine, but the removal of an additional stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.
