Sunstar Rear Sprocket 47T for KTM 85 SX 2003-2024 2-248147

The rear sprocket is the final drive component that directly controls your KTM 85 SX's acceleration, top-end speed, and engine load characteristics. A worn or mismatched sprocket forces your engine to work harder, reducing efficiency and throttle response. The Sunstar 47T delivers precision engineering and durability that competitive riders and serious enthusiasts depend on to maintain consistent power delivery lap after lap.

Sunstar's exclusive tooth-valley design increases chain contact area by 50%, transferring more power to the rear wheel with less slippage. The computer-optimized weight reduction holes cut unnecessary mass while innovative cleaning grooves at the tooth base minimize debris buildup—critical for maintaining chain longevity in aggressive riding conditions. This is a bolt-on replacement that requires no fabrication, making fitment straightforward on all KTM 85 SX models from 2003–2024.
