• Material: aerospace aluminum 7075-T6 (Ergal) — a weight/strength compromise suitable for road and off-road.
• Number of teeth: 51 — standard gearing to regain torque and engine response according to your setup.
• Chain pitch: 520 — compatible with 520 drive systems.
• Finish: "mud-resistant" treatment to facilitate the removal of debris and limit dirt adhesion.

This JT Sprockets sprocket is aimed at riders looking for a weight-saving part without sacrificing the mechanical integrity of their transmission. Its Ergal design reduces unsprung mass while providing the robustness expected on muddy trails or roads. The mud-resistant option helps keep the chain cleaner for more consistent performance between maintenance intervals.

Examples of applications: GAS GAS EC 200 RACING (2020), BETA RR 480 4T ENDURO EFI (2019), HM CRE 125 COMP SIX 2T (2015). Check the chain pitch and tooth/axle compatibility before installation or replacement.
