The addition of E-Start adds to the simplicity of this popular model and guarantees fast starting in all conditions.
Cylinder
The new cylinder retains a 66.4 mm bore and with the introduction of EFI for 2024, 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 the liveliness and throttle response from the engine. The perfect balance of rotating masses is achieved by balancing the weights of the crankshaft flywheel, the new rotor, and the counter balancer shaft.
Chromium molybdenum frame
The proven chromium molybdenum steel frame is refined for 2024. A new shock mounting, which is no longer connected to the main tube, significantly improves the anti-squat behaviour of the chassis. With optimised wall thickness in high stress areas improving reliability, the frame continues to offer advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability. The frame is finished off in a premium metallic blue powder coating with redesigned standard frame protectors offering superior protection, durability, and grip in any condition. Additionally, the inclusion of forged brackets on the lower frame rails allows for easy installation of the skid plate, which is available as a technical accessory.
Polyamide-reinforced aluminium subframe
Made from 60% polyamide and 40% aluminium, the new two-piece subframe for 2024 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
Matching the new frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability. Customised handlebar flex can be achieved by the new 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 split air forks now offer improved bottoming resistance thanks to a new hydrostop, which applies a progressive damping force in the last 40 mm of travel for even greater comfort. The WP forks are designed with a capsulated, adjustable air spring and pressurized oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a midvalve damping system, 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. For improved durability, new fork protection rings prevent dirt intrusion. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard.
Functional bodywork
Clean, Swedish-inspired design and ergonomics are tailored to allow riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points and surfaces in the rider triangle have been repositioned for 2024 to improve comfort on the motorcycle. A new, flatter seat offers unrestricted movement with a high grip cover ensuring riders stay firmly in place under hard acceleration.
Airbox
Designed with precisely positioned inlet ducts aimed at reducing drag and air flow deformation, the airbox ensures unrestricted airflow with 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 modulation in every condition. Meaning that 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 high-quality, Italian-made Brembo hydraulic systems' exceptional reliability.
Wheels and tyres
Assembled with CNC-machined hubs, strong spokes, and black-anodised alloy rims by D.I.D, the wheels of the TC 250 are fitted with DUNLOP GEOMAX MX33 Motocross tyres which feature a proven block-within-a-block design for more progressive cornering and superior grip. For improved on-track agility and stability through ruts, the TC 250 is fitted with a 110/90-19 rear tyre while a 80/100-21 front tyre ensures optimal handling on a variety of riding surfaces.
Exhaust system
The header pipe on the TC 250 is designed using innovative 3D modelling. The result is a perfect shape aimed at delivering the optimum performance characteristics while also being very compact ensuring sufficient clearance in tight rutted corners.
Cooling system
Manufactured from high-strength aluminium, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air in the most effective way. A large centre tube channels coolant through the frame to reduce pressure at this point in the system for a more consistent flow while a new internal thermostat further enhances reliability.
Fuel tank
A new 7.2 litre fuel tank integrates neatly into the revised bodywork. Due to the new fuel pump design and position, the tank is emptied further for increased running times. For improved safety, the external fuel line is specifically routed to make it less exposed and susceptible to damage.
EFI
The introduction of Electronic Fuel Injection on the TC 250 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. The exciting addition of EFI allowed our engineers to develop two different engine maps, which can easily be selected via the handlebar-mounted switch for a personalised riding experience. Additionally, an important reed valve revision improves intake tract sealing and prevents excess fuel build up in the engine on extreme up or downhill sections for clean running at all times.
E-Start
For guaranteed, easy starting in all conditions, the TC 250 now features highly convenient electric start technology for the very first time. The reliable system removes 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 now achieved via the same handlebar-mounted switch for improved ease of use and a simplified operation.
Map switch
Adding Electronic Fuel Injection (EFI) to the TC 250 allows for the introduction of two engine maps that cater for riders of all abilities. Map 1 is the standard option, that delivers linear, predictable power, while map 2 is aggressive with improved throttle response and a sharper, explosive power output. By simply pressing a button on the handlebar-mounted map switch, riders can toggle between the two options and select their chosen map.
EMS
The new Engine Management System (EMS) is designed to be smaller and lighter while also faster at processing data. It incorporates a new rollover sensor (ROS) which cuts the ignition and shuts off the engine for safety in the event of a severe crash, adding another level of safety to Husqvarna Motorcycles' new generation motocross line-up.
