Vehicle Information
KTM 85 SX Dirt Bike (2003-2026)
The KTM 85 SX has been a cornerstone in junior motocross racing from 2003 to 2026, consistently powered by an 85cc two-stroke, liquid-cooled engine. This high-performance dirt bike is renowned for its agility and competitive edge, featuring an 84.9cc single-cylinder engine paired with a 6-speed manual transmission and a hydraulic clutch. Throughout its production, the 85 SX has offered two primary wheel size configurations—17/14 and 19/16 inches—to accommodate various rider heights and skill levels, a consistent trim distinction since at least 2009. The model has seen several key evolutions. Introduced in 2003 as a new construction, it received significant updates in 2008 with a sturdier frame and improved engine, followed by a new chassis and power enhancements in 2011. A major redesign around 2018 introduced a chromoly steel frame and WP Xact suspension. The 2026 model continues this trend with further engine weight reduction (120g lighter), new triple clamps, and advanced WP XACT AER forks, alongside a redesigned subframe, ensuring continuous optimization for performance.
