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.
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.
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.
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.
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.
