[sprockets]
■Front
The front sprocket must be strong enough to reliably hold up under the power and torque.
High-precision processing of carefully selected materials.High performance and durability are achieved.
・Material: Chromium molybdenum steel (SCM)
・Heat treatment: carburizing and nitriding treatment
Surface treatment:Iron tetroxide coating
・Durability: 10000km-30000km

■Rear Steel
Highly durable steel rear sprocket.
If you are looking for durability rather than appearance and lightness, steel is recommended.
There is also a racing steel sprocket for 520 conversion for 1000cc supersports.
・Material: Steel (S45C)
Surface treatment:plating treatment
・Durability: 20000km-40000km


[Chain]
Motorcycle-specific chain with development supervised by a sprocket manufacturer
SUNSTAR, who have been producing sprockets for motorcycles for half a century, have developed this chain exclusively for motorcycles in pursuit of the best combination with the sprocket.

Motorcycle-specific chain developed for compatibility with sprockets.
The durability of the sprocket depends largely on the performance of the chain.
At the same time, the durability of the chain is greatly influenced by the performance of the sprockets.
The drivetrain of a motorcycle functions through the interaction of the chain and sprocket.
SUNSTAR, who have been producing sprockets for more than 60 years, have put all of their know-how into this product.

・The sprocket teeth and rollers are designed to optimize the fit (compatibility) and maximize the durability of both chain and sprocket.
・By machining holes in the pins, the weight is reduced and high strength is achieved.
・The grease filling inside the bushings, which could be said to be the most important thing for a seal chain, is done by a unique method that maximizes the amount of grease, and the gap between the bushings and pins is filled with grease to prevent wear, thereby greatly increasing the durability of the chain.

Each chain size is available in one grade for a wide range of displacements, so there is no need to hesitate when choosing a chain.
520 Size: Up to 800cc
525 Size: Up to 1300cc
530 Size: Up to 1400cc

■Color variation
・Gorgeous gold plating
The brightly hued gold plating is a symbol of high performance.
Combined with a champagne gold aluminum sprocket, it will give your wheels a glamorous look.

・Cool silver plating
The simple silver plating can be combined with sprockets of any color to create a chic look.

・Standard for great cost performance
This is a standard chain that maximizes cost performance by eliminating the plating process.
Though it is not plated, the performance is the same as that of the gold and silver type.
