The JT SPROCKETS ultra-light mud-resistant aluminum 210 - 520 (manufacturer reference JTA210.47BLK) is designed for demanding riders seeking a lightweight and durable transmission part for off-road or roadster use. Machined from aerospace-grade 7075-T6 aluminum (Ergal), it combines low inertia with mechanical strength suitable for muddy or rocky terrains.
The "mud-resistant" finish of the teeth minimizes the accumulation of debris and facilitates dirt removal, keeping the chain cleaner and providing more consistent control on technical trails. Its lightweight design contributes to a more responsive gear ratio while remaining compatible with the chain pitch of 520.
Installation and maintenance are made easier thanks to a machined finish and a tooth design aimed at reducing mud accumulation. Examples of compatible motorcycles in 520: BETA RR 480 4T (2024), HONDA CRF 450 X (2024), HM MOTARD 450 (2013). A sleek and high-performance sprocket for those looking to optimize their transmission without complexity.
