WP XACT front suspension

Rigorously tested by WP's research and development department, the 48 mm WP XACT closed cartridge spring forks fitted to the TX 300 Heritage model 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 for continued straight line stability and forward momentum. Both the compression and rebound settings can be quickly adjusted by hand using the easy access clickers. Additionally, the pump needed to adjust the air spring pressure in the forks is provided with each Heritage machine.

WP XACT rear suspension

The all-new WP XACT rear shock is 100 g lighter and 15 mm shorter than its predecessor yet the travel remains unchanged. Inside the shock is a Computational Fluid Dynamics (CFD) optimised main piston for improved initial comfort which provides strong hold-up in all conditions. Different sized holes in the shims allow them to open more easily which reduces the overall stress of the oil flow. Complete with low friction SKF seals and a revised linkage system, consistent damping, comfort, and traction are guaranteed with rebound and both high and low speed compression now adjustable by hand.

Swingarm

The swingarm is manufactured using a die-cast production process for optimal rigidity. To match the flex characteristics of the chassis, a 22 mm rear axle is utilised. Additionally, the swingarm is designed to enhance the durability of the chain glider while the chain guide features a rounded profile that makes it less prone to catching on external objects.

effortless ergonomics

Bodywork

The bodywork clearly showcases Husqvarna Motorcycles' progressive approach to offroad motorcycles while the Swedish heritage-inspired blue and yellow graphics create a distinctive look. The ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points have been repositioned for 2023 and together with a flatter seat profile, riders can move freely on the motorcycle for total control at all times.

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 the function of the clutch, remain identical in cold or hot conditions, as well as over time. Countless hours of testing have proven the reliability of the high-quality, Italian-made Brembo hydraulic system.

Hydraulic brakes

The highest level of performance is guaranteed thanks to the class leading Brembo calipers and controls. Together with GSK wave discs (260 mm disc front and 220 mm rear), which are designed to prevent mud from building up, superior stopping power and braking confidence is assured in all conditions.

EFI

The introduction of 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 Hitachi-Astemo (formerly 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 TX 300 Heritage model features highly reliable electric start technology 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 improved ease of use and a simplified operation.

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 new Engine Management System (EMS) is designed to be smaller and lighter while being faster at processing data. It incorporates a new rollover sensor (ROS) which cuts the ignition and shuts off the engine in the event of a severe crash, adding another level of security to the Husqvarna Motorcycles' new generation line-up.

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.
