Description
The Excel Takasago aluminum alloy rim is the benchmark in off-road racing rim technology. Every Excel MX rim is engineered and designed to perform in extreme hostile environments where other rims routinely fail. In fact, Excel has won more Motocross and off-road championships - worldwide - than all competitors combined! Part of the secret is in our exclusive 7000 series aluminum alloy which has a 50% higher yield strength than our competitor's 6 series aluminum. Also, exclusive know- how in extrusion design, complex multi-step forming, advanced robotics welding, and in hard anodizing such a tough and complex material is key to Excel's strength and world market dominance. They are the choice of all Factory Works and Privateer Teams worldwide and the choice of OEM builders such as Honda, Kawasaki, KTM, Suzuki and Yamaha.
FEATURES
- Anodized aluminum construction
- Available in many anodized colours as listed
- All rims must use Excel spoke and nipple sets, unless otherwise noted (OEM nipples are too small)

Vehicle Information
KTM 525 EXC Dirt Bike (2003-2007)
The KTM 525 EXC, produced from 2003 to 2007, was a highly regarded off-road racing motorcycle. Known for its robust "RFS" (Racing Four Stroke) engine, this model featured a single-cylinder, liquid-cooled 510.4 cc engine, often marketed as 525cc. It delivered approximately 60 to 61 horsepower and was equipped with a Keihin MX FCR 39 carburetor and a six-speed gearbox, making it a formidable competitor in its class. Throughout its production run from 2003 to 2007, the KTM 525 EXC maintained a consistent core design, undergoing continuous refinements rather than full generation changes. Key updates included a significant suspension upgrade in 2003 with 48mm WP-USD forks and improved rear shock, alongside reinforced wheel hubs. The 2004 model saw strengthened clutch plates, a one-piece flywheel, and a new single-tube exhaust system for enhanced low-end torque. Further refinements in 2005 brought an upgraded FCR-MX carburetor and redesigned plastics, with the 2006 and 2007 models benefiting from these cumulative improvements. Specialized trims like the 525 EXC-G Racing and 525 XC Desert Racing were also introduced in 2006. Q: How do I ensure I'm selecting parts for my specific KTM 525 EXC model year?
