Manufacturer reference: JTR808.50SC — JT Sprockets 808 mud-resistant steel sprocket, pitch 520, 50 teeth. Designed for the transmission of Cross and Roadster machines, this sprocket fits into chain replacement or gearing projects.
- Material: C49 alloy steel
- Number of teeth: 50
- Chain pitch: 520
- Type: Standard, series 808
- Finish: mud-resistant profile
The mud-resistant profile of the sprocket limits the accumulation of mud and debris between the chain and the teeth — a benefit for off-road sessions or rides on wet trails. Its standard design makes it easy to mount on most 520 transmission kits without the need for specific adaptations.
Compatible with many cross and roadster machines, it is often found as a replacement part on models such as SUZUKI RM-Z 250 (2026), RM-Z 450 (2025), or RMX 450 (2019). Ideal for riders looking for a robust and easy-to-install part to master gearing and transmission behavior.
