Benefits of this bike

01. Faster and wiser

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.

Crankcases:

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.

Gearbox: 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.

02. Ride easier

Chromium molybdenum frame: The chromium molybdenum steel frame features optimised wall thickness in all high stress areas for reliability and offers advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability. The frame is finished off with a premium metallic blue powder coating with standard frame protectors offering superior protection, durability, and grip in any condition.

Polyamide-reinforced aluminium subframe: Made from 60% polyamide and 40% aluminium, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 1.8 kg. The lower subframe spars and frame mounts are manufactured from cast aluminium for significantly improved reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.

Triple clamps: Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for increased stability. Handlebar flex can be customised with the handlebar clamp that offers two mounting options - rubber-damped for less vibration, or fixed for enhanced front-end feedback. The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.

WP XACT front suspension: Designed as a closed cartridge system, the 48 mm WP XACT forks have a capsulated, adjustable air spring and pressurised oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a mid-valve damping system, together with a hydrostop that applies a progressive damping force in the last 40 mm of travel, the forks provide precise feedback to the rider. The settings are easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. A pump to adjust the air spring pressure is provided with each machine.

WP XACT shock absorber: The WP XACT rear shock offers 293 mm of travel. Inside the shock is a Computational Fluid Dynamics (CFD) optimised main piston for improved initial comfort, which provides strong hold-up in all conditions. Differently sized holes in the shims allow them to open more easily, which reduces the overall stress of the oil flow. Complete with low friction seals fitted throughout the linkage system, consistent damping, comfort, and traction are guaranteed with rebound and both high and low speed compression adjustable by hand.

Swingarm: The swingarm is manufactured using a die-cast production process for optimal rigidity. To optimise and match the flex characteristics of the new chassis, a 22 mm rear axle is utilised. Additionally, the chain guide has a smooth profile to prevent it from catching on external objects.

03. Effortless ergonomics

Functional bodywork:

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.

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.

Footrests: 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.

04. Master your art

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.

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.

05. Technologically advanced

EFI: 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.

E-Start: 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.

EMS: 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.
