XAM A4533X47 520 Premium Rear Sprocket for Triumph 2006-2018 -47 Teeth

Features

• If only the film of hard alumite is used, the contact surface pressure may be high, fine vibration, or seizure may occur if it is used in a place where friction occurs.
• This hard alumite has independent lubrication performance and improved anti-friction performance in sprocket.
• Molybdenum dioxide that has penetrated throughout the microspores of alumite due to electrode position greatly reduces the frictional resistance of the hard coating.
• In the friction test, the durability performance several times higher than standard hard alumite is realized.
• Approximately 130% to 150% improvement compared with high hardness standard alumite.
