The perfect mid-size balance bike

Engine

The TC 125 engine sets the standard for performance in the highly competitive 125 cc class and weighs in at just 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 centralised, 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.

Chromium molybdenum frame

With an optimised distribution of material around the steering head and upper shock mount, the frame delivers confidence-inspiring handling and assured stability when entering corners. To complement the overall look of the machine, the chromium molybdenum chassis is finished with a premium, metallic blue powder coating. The finishing touches are the frame protectors, which not only protect the paintwork, but also provide riders with additional grip, even in the toughest conditions.

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 endure precisely calculated geometry for increased stability. Handlebar flex can be customised 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 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) optimised main piston, ensuring superior initial comfort and predictable performance in all conditions. To give riders the option of creating a personalised set-up, rebound, as well as the high and low-speed compression settings, can all be adjusted easily by hand.

Swingarm

The swingarm is manufactured using a die-cast production process and designed with a calculated level of rigidity. To further complement and optimise the flex characteristics of the chassis, a 22 mm rear wheel axle is utilised. 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-mould 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 optimises 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 callipers, made from single pieces of aluminium 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 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.

Wheels and tyres

CNC-machined hubs, strong spokes, and high-strength, black-anodised alloy rims by D.I.D are used to assemble the wheels. They are complete with the latest Dunlop MX34 tyres, 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 aluminium 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 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. A reliable, threaded radiator cap allows for easy inspection of the coolant level before each ride.

Fuel tank

The 7.2-litre 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 personalised 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, 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

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 centre of gravity, the handling of the TC 125 is uncompromised. The engine is easily started and stopped via the same handlebar-mounted switch for improved 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.
