Vehicle Information
Husqvarna TX 300 Dirt Bike (2017-2026)
The Husqvarna TX 300, a prominent off-road racing motorcycle, has seen significant evolution from 2017 to 2026. Designed for closed-course competition, it is powered by a single-cylinder, two-stroke engine with a consistent displacement of 293.2 cc throughout this period. Significant changes have marked its evolution. Initially carbureted (TX 300) from 2017 to 2019, it transitioned to electronic fuel injection (TX 300i) in 2020. A new generation was introduced in 2023, featuring a redesigned engine for Throttle Body Injection (TBI) and a new frame. In 2025, a lighter frame and revised WP suspension settings were added, alongside the introduction of the "Heritage" model. Q: Is this product compatible with my Husqvarna TX 300?
