TX 300 2017
The future 2-stroke

Completely new for 2017, the TX 300 signifies the constant development and secure future of the historic 300cc 2-stroke in the Husqvarna off-road line-up. With a newly designed chassis based on the new generation 2016 FC and TC models, the TX 300 is a purpose-built closed course racing 2-stroke with off-road specific features. A larger fuel tank, an 18-inch rear wheel and a side-stand increase the ability and usability of the TX for its intended purpose. Additionally, the lightweight 2-stroke engine is efficienct, centralizes mass and features very little vibration thanks to a counter balancer shaft. As a result the TX 300 now offers a refined and manageable closed course racing package.

Features and Benefits

Engine
The 300cc 2-stroke engine has for long been the best combination of unsurpassed power and lightweight construction. The simplicity and low maintenance cost of the 2-stroke motor has made it a favorite amongst riders for generations. The TX 300 features an advanced construction with shaft arrangements aimed at centralizing oscillating mass. A counter balancer shaft reduces vibration while a twin-valve controlled power valve ensures optimal performance.
Transmission
A 6-speed semi-close ratio gearbox compliments the off-road usage of the TX 300. An innovative shift lever reduces dirt build up guaranteeing easy operation in even the toughest conditions.
Crankcases
The TX 300 engine is designed with mass centralization as a key theme. As a result the lightweight, die-cast engine cases are developed to accommodate the specific location of shaft arrangements. Additionally the counter balancer shaft is integrated in a very compact manner having little affect on the compact design.
Carburettor
The TX 300 features a 38mm flat slide Mikuni TMX carburettor. This carburettor provides a smooth and controllable power delivery with optimal performance over the entire RPM range. Additionally, the carburettor has minimal sensitivity to changes in temperature and altitude which reduces the need for setting changes in different conditions.
Chromoly steel frame
The hydro-formed, laser-cut and robot-welded frame expertly crafted by WP Performance Systems is specifically designed with calculated parameters of longitudinal and torsional flex which best benefit handling and suspension functionality. The frame is finished off with a premium white powder coating and standard frame protectors guaranteeing supreme protection and durability.
Composite carbon fibre subframe
The composite subframe is a design unique to Husqvarna showcasing pioneering technologies and innovation. This 3 piece component is made up of 30% carbon fiber making it remarkably light (3.1 lbs.) and also particularly strong. Specific care is taken to create a certain rigidity for optimal handling and rider ergonomics.
WP AER 48
The 48 mm split air fork features an insulated air spring and pressurized oil chamber for progressive and consistent damping. The new component is lightweight and easily adjustable via a single air pressure valve for pre-load (on the left leg) as well as easy access clickers adjusting damping with 30 clicks (on the right leg). Additionally, the air pump needed to adjust air pressure in the fork will be provided as standard.
WP rear shock
The WP DCC rear shock is designed to provide advanced damping characteristics while conforming to a compact and lightweight design. With a pressure balance inside the shock, damping is improved resulting in greater rider comfort and handling while the outer contour of the reservoir increases cooling. The component is also fully adjustable and matched to a linkage system with a specific geometry to deliver the best possible traction and progression with a rear wheel travel of 300 mm.
Pro Taper handlebar
The Pro Taper handlebar is second to none for function and style. Manufactured to exacting standards, the Pro Taper handlebar features class-leading fatigue resistance while adding minimal weight. The Pro Taper logos are chemically applied and are scratch and peel resistant. The large Husqvarna bar pad has optimal impact resistance, while the standard handguards offer maximum roost protection.
Brembo brakes
Class-leading Brembo calipers and controls with high quality GSK discs deliver superior stopping power instilling confidence in any condition. 260mm disc front and 220mm rear.
Magura hydraulic clutch
The reliable, high quality, German-made 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.
Self cleaning footpeg mount
The Husqvarna frame features an innovative, self -cleaning footpeg mount which prevents the build-up of dirt collected through deep ruts or muddy terrain. As a result, the footpeg will spring back into its original position even in the toughest conditions. For riders who prefer a higher footpeg set-up, the MY17 enduro footpegs can be fitted raising the position by 6mm.
Electric and kick start
The TX 300 is fitted with an electric starter located below the engine. This position ensures that the unit is always protected. Additionally, the system is powered by a lightweight and powerful Li-Ion battery which is 2.2 pounds lighter than a conventional battery. A standard kick starter is fitted as standard as a back up.
Map select switch
The engine characteristics can be tailored thanks to the standard map switch that modifies the CDI curve between two ignition curves according to rider preference, conditions and terrain. Further optimisation of the power delivery can be obtained by varying the spring stiffness in the exhaust valve.
Standard off-road equipment
A large 2.65 gallon fuel tank gives the TX 300 the extra range needed for longer loops. The 6-speed semi-close transmission is perfectly suited for tackling the toughest off-road courses. The rear wheel is an 18-inch unit with Dunlop AT 81 off-road tires front and rear. A side stand completes the off-road transformation of the TX 300.
Wheels
Black high-strength alloy rims by DID are coupled to CNC machined hubs using lightweight spokes and silver anodised aluminium nipples.
