Following yesterday’s announcement of Husqvarna’s 2017 motocross models, Husqvarna USA have pulled the covers back on their cross-country TX 300, FX 350 and FX 450.
 

With elements of both motocross and enduro Husqvarnas, the bikes come in three sizes - FX 350, FX 450 and completely new for 2017 the TX 300. While fully rolled out in the USA, the TX and FX models will have limited availability in Europe too*…

TX 300

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 efficient, centralises 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.

Engine

The 300cc 2-stroke engine has 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 favourite amongst riders for generations. The TX 300 features an advanced construction with shaft arrangements aimed at centralising 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 centralisation 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.

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.

WP AER 48

The 48 mm split air fork features an insulated air spring and pressurised 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.

Standard off-road equipment

A large 2.65 gallon fuel tank gives the TX 300 the extra range needed for longer loops. The rear wheel is an 18-inch unit with Dunlop AT 81 off-road tires front and rear. Pro Taper handlebars, self-clewing foot pegs and a side stand complete the off-road transformation of the TX 300.
