The TX 300i signifies the constant development and secure future of the historic 300cc 2-stroke in the Husqvarna off-road line-up. Featuring the latest technology, the TX 300i 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 usability of the TX for its intended purpose. Additionally, the lightweight 2-stroke engine is efficienct using modern electronic fuel injection, centralizes mass and features very little vibration thanks to a counter balancer shaft. As a result the TX 300i offers a refined and manageable closed course racing package.
The TX 300i features a pioneering electronic fuel injection system. This comprises of a set of fuel injectors positioned at the transfer ports which deliver the ideal amount of fuel to the engine in every condition. This not only reduces fuel consumption and emissions but also delivers a clean & smoother power delivery giving the loved 2-stroke a new edge.
The cylinder design includes two inlet positions located on the transfer ports at the rear of the cylinder where a pair fuel injectors are mounted. The injectors deliver fuel downwards into the transfer port guaranteeing excellent atomisation with the air travelling upward to the combustion chamber. This ensures a more efficient combustion resulting in reduced fuel consumption and emissions.
The TX 300i uses a 39 mm throttle body which regulates the amount of air entering the engine via a butterfly operated by dual throttle cables connected to a new handlebar throttle assembly. Unlike 4-stroke throttle bodies, fuel is not introduced at this point but rather 2-stroke oil is mixed with the air entering the engine to lubricate the crankshaft, cylinder & piston.Additionally, a throttle position sensor (TPS) relays airflow data to the ECU which in turn calculates the amount of oil and fuel delivered to the engine while a bypass screw regulates the idling speed and a cold start device opens a bypass providing more air for cold starts.
WP XACT FRONT SUSPENSION
The 48 mm split air fork features a capsulated air spring and pressurized oil chamber for progressive and consistent damping. The forks feature revised settings and are easily adjusted via the single air pressure pre-load valve, as well as through easy access clickers for compression and rebound. Additionally, the air pump needed to adjust the fork’s air pressure is provided as standard.
WP XACT REAR SUSPENSION
With an updated settings, the WP XACT rear shock provides advanced damping characteristics for unsurpassed traction and energy absorbtion. A pressure balance inside the shock ensures consistent damping, resulting in superior rider comfort and feeling.
MAP SELECT SWITCH
The engine characteristics can be tailored thanks to the standard map switch that modifies the power delivery according to rider preference, conditions and terrain.
