About this product
About this product
Maximize your motorcycle's performance with the JT Sprockets Twinstar Hybrid Sprocket. This innovative sprocket combines the strength of steel with the lightweight properties of aluminum, delivering superior power transfer and extended lifespan.
Description
The JT Sprockets Twinstar hybrid sprocket features a heat-induction hardened high-carbon steel outer ring. This advanced tempering process achieves a hardness up to six times longer-lasting than a 7075-T6 aluminum sprocket, significantly enhancing power transfer and ensuring exceptional durability. The lightweight aviation-grade Ergal 7075-T6 aluminum core reduces rotational mass, improving acceleration and handling. Precision laser cutting and CNC machining guarantee an ultra-lightweight design optimized for racing performance. This rear drive sprocket is finished in striking black and gold, adding a touch of style to your ride and ensuring that you get the most out of your motorcycle’s power delivery.
