JT Sprockets TwinStar Hybrid Rear Orange

The JT Sprockets TwinStar Hybrid rear sprocket is a bi-metal motorcycle drive sprocket. It pairs a lightweight aluminum carrier with a hardened steel outer ring. JT developed it to be one of the lightest and most durable rear sprockets in its class. It suits riders who want less rotating weight without giving up wear life.

Key Features:

• Aviation-grade aluminum core: The carrier is made from Ergal 7075-T6 aluminum to keep weight down.
• Hardened steel outer ring: The ring is heat-induction hardened. JT says it lasts up to six times longer than a standard 7075-T6 aluminum sprocket.
• Precision manufacturing: The sprocket is made with laser cutting and CNC machining.
• Race-proven design: JT developed it through an extensive test program that included top-level motocross events and the 2020 Dakar Rally.
• Lighter than steel: The lower weight helps reduce rotating mass and power loss compared with an all-steel sprocket.

The TwinStar Hybrid combines the light weight of aluminum with the wear resistance of steel. It is a good choice for street, off-road and competition use. Choose the variant that matches your required tooth count and sprocket pattern.
