JT. Aluminium Ultra-Light Self-Cleaning 822 - 520 SprocketRef : JTC00545A / 1096577003

Ultra-light JT Sprockets crown made of 7075-T6 aluminum (Ergal) specifically machined for motocross, quad, and roadster practices. Its aerospace construction reduces rotational weight while maintaining good mechanical strength for intense outings and typical accelerations on muddy terrains or tight trajectories.

• Material: 7075-T6 aluminum (Ergal), black finish
• Number of teeth: 49 teeth
• Chain pitch: 520 (compatible with 520 transmission)
• Finish: mud-resistant profile to facilitate particle ejection
• Type: standard, direct mount replacement

The mud-resistant finish helps limit the accumulation of mud and gravel between the chain and the crown, contributing to a smoother transmission operation on difficult terrains. The lightweight design reduces unsprung mass, noticeable in the responsiveness of accelerations and handling.

Suitable for mounting on vehicles equipped with 520 and for those looking for a lightweight and refined alternative to the original crown. Examples of compatible models: GAS GAS EC 200 RACING (2020), BETA RR 480 4T ENDURO EFI (2019), HM CRE 125 COMP SIX 2T (2015).
