Next Generation Racing Steel" realizes weight reduction and ultra durability of the entire suspension.
Exclusive for super sports models 520 Converted Lightweight / Super Durable Steel Sprocket
The power of the latest supersports is in excess of 200 horsepower, making it a very tough environment for sprockets and chains.
This is not only because of the high power, but also because the traction control system (part of the electronic control system), which automatically controls the vehicle's ability to follow the road and run efficiently, keeps the chain and sprockets under a constant and high variable load. The lightweight aluminum sprocket, which has absolute superiority on the circuit, has become one of the concerns in terms of durability and frequency of replacement in long endurance races.
Sunstar's development team has conducted numerous tests and collected data for top teams in Japan and overseas, such as Yoshimura Suzuki MOTUL Racing and MUSASHI RT HARC-PRO, and has solved problems that occur in harsh environments. And now, this product is released to the public as Racing Steel Series. All production is done at Sunstar's Shiga plant, and the roundness accuracy and hardening treatment, which greatly affect durability, can be used with confidence.
The sprocket wear is greatly reduced by the racing steel, which reduces the overall weight of the suspension and increases the durability of the chain. Not only teams competing in championship races, but also users who enjoy circuit driving can easily experience the "next-generation 520 conversion tune".

The OEM was a color like cheap Wrench, so it's a strong enough color to be used in this Race anyway. I bought it in black and it looks great with the gold chain!View Detail
After running 20,000 km, we confirmed that one of the chains was stretched and decided to replace it. In that case, it is better to do SprocketFront and Rear at the same time. I bought it because I heard it was good.View Detail
