01. Faster and wiser

Engine

The TX 300 engine is at the pinnacle of 2-stroke performance and weighs just 23.9 kg. Expertly assembled with the latest technical innovations, the TX 300 features electronic fuel injection (EFI) and an electronic exhaust control for lower running costs and reliability. Configured with no separate oil tank, pre-mixed fuel is required, which is identical to the motocross models. A proven e-start adds to the simplicity of this popular model and guarantees fast starting in all conditions.

Cylinder

The cylinder features a 72 mm bore and 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 unrivalled performance.

Crankcase

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 in the perfect position for optimised mass centralisation. This clever design aids the overall balance and agility of the TX 300 while the symmetrical engine mounts offer a calculated level of flex.

Crankshaft

Designed with weight reduction and performance in mind, the crankshaft in the TX 300 engine helps to provide an instant throttle response, and contributes to the lightweight feel of the motorcycle. The perfect balance of rotating masses is achieved by balancing the weights of the crankshaft flywheel and the rotor, and thanks to the innovative counter balancer shaft, engine vibration is kept to an absolute minimum.

Counter balancer shaft

The TX 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 TX 300 features a dampened diaphragm steel (DDS) clutch, which includes a single-diaphragm steel pressure plate instead of traditional coil springs. It integrates a damping system for better traction and durability. The clutch basket is a single-piece CNC-machined steel component and allows the use of thin steel liners that contribute to the compact design of the engine.

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 are designed to improve leverage, which ensures significantly smoother and more precise shifting.

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 strength at the lowest possible weight. Injection-molded polyamide is used to construct the upper section of the subframe to enable specific flex characteristics.

Triple clamps

Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for 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

Rigorously tested by the WP research and development department, the 48 mm WP XACT Closed Cartridge spring forks fitted to the TX 300 provide exceptional comfort. Inside the forks, mid-valve pistons optimise oil flow and prevent foaming for consistent and predictable damping at all times. A hydrostop, active in the final 68 mm of travel, reduces the impact of harsh and high-speed landings to maintain forward momentum. Both the compression and rebound settings can be quickly adjusted by hand using the easy access clickers found on top of each fork leg.

WP XACT rear suspension

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.

03. Effortless ergonomics

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.

Tool-less 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, Italian-made 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, they are less susceptible to hooking on deep ruts and trackside barriers. This was 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 fitted with versatile Dunlop AT82 tyres. The front ensures precise cornering, while the rear provides excellent traction across varied terrain.

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 8.5-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.

Exhaust system

Tailored specifically to the TX 300 engine using an innovative 3D design process, the header pipe ensures maximum power across the rev range. The muffler features an aluminium mounting bracket for strength at the lowest possible weight, with an advanced internal construction ensuring excellent noise damping without sacrificing performance.

05. Technologically advanced

EFI

The electronic fuel injection on the TX 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. The EFI allows a choice of two different engine maps, which can easily be activated via the handlebar-mounted switch for a personalised riding experience. Additionally, the sealing around the reed valve intake tract prevents excess fuel build up in the engine on extreme up or downhill sections for clean running at all times.

E-Start

To ensure fast starting in all conditions, the TX 300 features a highly convenient electric start. The reliable system removes the need for a kickstart completely. With the 12.8V 2 Ah Lithium-Ion battery located under the seat and close to the centre of gravity, the handling is uncompromised. The engine is easily started and stopped via the same handlebar-mounted switch for ease of use.

Map Select Switch

By using the Map Select Switch, the engine characteristics can be tailored to modify the power delivery according to rider preference, conditions, and terrain. It has two settings that can be safely toggled between while riding, by simply pressing a button on the handlebar-mounted Map Select Switch. Map 1 (white) is the standard option, that delivers linear, predictable power, while map 2 (green) is more aggressive with improved throttle response and sharper, explosive power output.

EMS

The engine management system (EMS) is designed to be small, light, and fast at processing data. It incorporates a rollover sensor (ROS) which 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 becoming 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.
