Engine

The engine is at the pinnacle of 2-stroke performance, producing 53 hp and weighing just 23.9 kg. Complete with the latest technical innovations, the TC 250 Heritage model comes with electronic fuel injection (EFI) for reduced running costs, removes the need for jetting changes, and improves reliability. The addition of electric start adds to the simplicity of this popular model and guarantees fast starting in all situations.

Cylinder

The cylinder has a 66.4 mm bore and thanks to the EFI, an electronic exhaust control system is utilised instead of a traditional powervalve. 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

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 to position the shaft arrangements perfectly for optimised mass centralisation. This clever design aids the overall balance and agility of the TC 250 Heritage machine while the symmetrical engine mounts enhance the flex characteristics of the chassis.

Counter balancer shaft

The TC 250 Heritage model 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 250 Heritage machine 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 maximum traction and durability.

Gearbox

The TC 250 Heritage model features a 5-speed gearbox manufactured exclusively by Pankl Racing Systems for the highest level of durability and ensures smooth and precise shifting.

Chromium molybdenum frame

All Heritage models benefit from an advanced frame that is engineered with specific wall thicknesses in high stress areas for strength and a calculated level of flex. Overall, the chassis offers exceptional cornering agility, unparalleled rider feedback, energy absorption, and confidence-inspiring straight-line stability. The frame is finished with a premium white powder coating, unique to the Heritage models, with 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 maximum 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 assured 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 front suspension

The 48 mm WP XACT forks feature a closed cartridge system and a capsulated, adjustable air spring. Together with a pressurised oil chamber, the forks deliver a smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with the mid-valve damping system, the forks provide precise feedback to the rider. To ensure maximum forward momentum after heavy landings, a hydrostop applies a progressive damping force in the last 40 mm of travel. 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. Additionally, the pump needed to adjust the air spring pressure in the forks is provided with each Heritage machine.

WP XACT shock absorber

Inside the WP XACT rear shock is a Computational Fluid Dynamics (CFD) optimised main piston for exceptional comfort with the overall design of the shock providing strong hold-up in all conditions. The linkage system features low-friction seals for unrestricted suspension performance with a lightweight bolt utilised to save weight. Rebound and high and low speed compression settings can be easily adjusted by hand to simplify any set-up changes.

Swingarm

The swingarm is manufactured using a die-cast production process for optimal rigidity. To optimise and match the flex characteristics of the chassis, a 22 mm rear axle is utilised. Additionally, the chain slider is exceptionally durable while the chain guide is manufactured with a rounded profile to ensure it is less prone to catching on external objects.

03. Effortless ergonomics

Functional bodywork

The bodywork has been designed to allow riders to perform at their very best for extended periods of time with the distinctive blue radiator shrouds unique to the Heritage models. Following countless hours of testing and refinements, the large contact points and surfaces in the rider triangle enhance comfort, which in turn helps to reduce fatigue. A flat seat profile allows for unrestricted movement while the blue, high-grip seat cover ensures riders stay firmly in place under hard acceleration.

Airbox

A strong, one-piece airbox with optimised air intake tracts ensure an unrestricted flow of air for maximum power. 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 levels of quality and performance are guaranteed as the class leading Brembo brake calipers are made from single pieces of 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.

ProTaper handlebar

Developed between Husqvarna Mobility 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 they are less susceptible to catching on deep ruts, take-offs when scrubbing, and trackside barriers. This was achieved by the narrow mounting design in the frame layout.

EFI

The electronic fuel injection system on the TC 250 Heritage model 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 allows for 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, the reed valve system 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 250 Heritage model features a highly reliable electric start 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 ease of use and a simplified operation.

Map Select Switch

The electronic fuel injection (EFI) on the TC 250 Heritage machine allows for 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.
