Renthal Yamaha Ultralight Black Rear Sprocket Features:

• Ultralight rear sprockets are 66% lighter than steel.
• Individually CNC machined to the tightest possible tolerances, ensuring anaccurate and reliable fit.
• High strength specially enhanced 7075 T6 aluminium alloy is used to create the perfect rear sprocket, that is both lightweight, durable and strong.
• Self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.
