Polyamide-reinforced aluminium subframe
Made from 60% polyamide and 40% aluminum, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 3.9 lb (1.8 kg). The lower subframe spars and frame mounts are manufactured from cast aluminum for significantly improved reliability. The upper section of the subframe is made from injection-molded 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 provide precisely calculated geometry for stability. Handlebar flex can be customized with the handlebar clamp, which 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-USD front suspension
Rigorously tested by the WP research and development department, the 48 mm WP XACT closed cartridge spring forks fitted to the TC 125 provide exceptional comfort. Inside the forks, mid-valve pistons optimize oil flow and prevent foaming for consistent and predictable damping at all times. A hydrostop, active in the final 40 mm of travel, reduces the impact of harsh and high-speed landings to maintain forward momentum. Both compression and rebound settings can be quickly adjusted by hand using the easily accessible clickers located on top of each fork leg.
WP XACT shock absorber
The WP XACT rear shock features a Computational Fluid Dynamics (CFD) optimized main piston, ensuring superior initial comfort and predictable performance in all conditions. To give riders the option of creating a personalized set-up, rebound, as well as the high and low-speed compression settings, can all be adjusted easily by hand.

The swingarm is manufactured using a die-cast production process and designed with a calculated level of rigidity. To further complement and optimize the flex characteristics of the chassis, a 22 mm rear wheel axle is utilized. A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners.
Functional bodywork
The ergonomic bodywork was designed to ensure that riders can perform at their best throughout every race. This was achieved through extensive testing, with the smooth contact points in the rider triangle allowing racers to grip the machine tightly with their legs, reducing fatigue. The radiator shrouds, featuring in-mold graphics, contribute to the progressive appearance of the machine, while a tall, wide seat offers unrestricted movement. A high-grip seat cover also helps keep riders securely in place under hard acceleration.
Airbox
A strong, one-piece airbox optimizes air intake by reducing deformation. This design provides an unrestricted flow of air for maximum power, without compromising filter protection. The Twin Air filter can be easily inspected without tools by simply removing the left side panel.
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 Brembo hydraulic system.
Hydraulic brakes
Class-leading Brembo brake calipers, made from single pieces of aluminum for strength, are fitted front and rear to ensure high braking performance. Together with 260 mm front and 220 mm rear discs, both designed to prevent mud build-up, effective stopping power in all conditions is assured. The strong rear brake pedal is highly durable, and less susceptible to damage when riding through deep ruts.
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 personalized 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.
Wheels and tires
CNC-machined hubs, strong spokes, and high-strength, black-anodized alloy rims by D.I.D are used to assemble the wheels. They are complete with the latest Dunlop MX34 tires, with the front ensuring precise cornering, while the rear provides excellent traction across varied terrain.
Exhaust system
Tailored specifically to the TC 125 engine using an innovative 3D design process, the exhaust pipe ensures maximum power across the rev range. The silencer is easily mounted using an aluminum bracket for strength at the lowest possible weight, with an advanced internal construction ensuring excellent noise damping without sacrificing performance.
Cooling system
Manufactured from high-strength aluminum, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air through them in the most effective way. A large center tube through the frame reduces pressure at this point in the system for a consistent coolant flow, while an internal thermostat further enhances reliability. A new threaded radiator cap allows for easy inspection of the coolant level before each ride.
Fuel tank
The 1.9-gallon (7.2-liter) fuel tank integrates neatly within the ergonomic bodywork and features a strong rubber cushion beneath it to protect the frame from wear. For maximum durability, the external fuel line is specifically routed to make it less exposed and susceptible to damage. Additionally, the protective cap for the fuel filter prevents dirt and water from entering the system and shields it from impact damage.
EFI
The electronic fuel injection system on the TC 125 brings many benefits. The ECU constantly analyses the running condition of the engine and guarantees to deliver 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 personalized riding experience. Map 1 (white) is the standard map for linear, progressive power designed for hard pack while Map 2 (green) is more aggressive and suited to sand and heavier track conditions. Additionally, the reed valve system is designed to prevent excess fuel build up, which would lead to rich running of the engine in extreme up or downhill sections.
E-Start
To ensure fast starting in all conditions, the TC 125 features a highly reliable electric start. The system removes the need for a kickstart completely and the additional space created above the engine is used to house the EFI and electronic exhaust control. With the 12.8V 2 Ah Lithium-Ion battery located under the seat and close to the center of gravity, the handling of the TC 125 is uncompromised. The engine is easily started and stopped via the same handlebar-mounted switch for ease of use.
Map switch
The electronic fuel injection (EFI) on the TC 125 offers two engine maps to suit different track conditions. Map 1 (white) is designed for hard pack and slippery tracks as it delivers linear, predictable power. Map 2 (green) is aggressive and designed for sand and heavy track conditions to ensure maximum performance and reliability. Riders can easily engage either map by pressing a button on the handlebar-mounted Map Select Switch.
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 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.
