Vehicle Information
KTM 525 SX Dirt Bike (2003-2006)
The KTM 525 SX, produced from 2003 to 2006, was a formidable motocross machine renowned for its powerful four-stroke engine and race-ready design. Featuring a liquid-cooled, single-cylinder engine with a displacement of approximately 510.4 cc, it consistently delivered strong performance. The 2003 model, for instance, produced 61.0 horsepower and 61.0 Nm of torque, with similar output maintained throughout the series. The primary trim offered was the "525 SX" or "525 SX Racing," without distinct sub-trims. A significant evolution occurred in 2003. This year introduced a lighter crankshaft, a revised cylinder head, and a new Keihin FCR-MX 41 carburetor with a hot-start feature. Chassis improvements included White Power USD 48 mm forks with preload adjusters, a larger 26 mm front-wheel axle, and a modified WP PDS suspension strut. Models from 2004 to 2006 largely carried over these enhanced specifications, focusing on minor refinements rather than major overhauls. FAQ:
