Vehicle Information
KTM 105 SX Dirt Bike (2004-2011)
The KTM 105 SX (2004-2011) was a highly competitive two-stroke motocross bike designed for youth riders transitioning to larger machines. Throughout its production, it consistently featured a liquid-cooled, single-cylinder, two-stroke engine with reed valve intake and a Keihin carburetor, providing robust performance in the supermini class. While specific horsepower figures were not consistently published, the focus was always on an optimal power-to-weight ratio and engine characteristics for competition. A notable change occurred in 2005: the 105 SX was not offered as a standalone model. Instead, KTM provided a 105cc Conversion Kit, including a cylinder, cylinder head, piston, and gaskets, to upgrade an 85 SX. For other years, the engine displacement varied slightly between 104 cc and 104.9 cc, but the core architecture remained consistent. The model did not feature distinct "Pro" or "Factory Edition" trims; the 105 SX itself was the primary offering. KTM continuously refined the engine and WP suspension components to maintain its competitive edge. Q: How do I ensure I select the correct parts for my KTM 105 SX?
A: Please use the year and edition selector on this page to confirm compatibility for your specific model year.
