[forged steel FRONT]
■Feature 1: Chromium molybdenum steel casting material is used as material The front sprocket receives the engine power directly, it should be strong enough. Sunstar uses chromium molybdenum steel forging to increase the strength of this product. *Some of them are not forged.
■Feature 2: Extensive offset lineup Offsetting the chain line is essential when widening the rear wheel and installing larger tires. The offset sprocket is a necessity to cope with this. Sunstar offers a wide range of offset dimensions. High precision Sunstar sprockets for advanced undercarriage customization.
■Feature 3: Convertible front sprocket for race use Special sprocket for converting the chain size, which is common in racing vehicles. This is a lightweight sprocket with lightweight holes drilled mainly for super sports vehicles.

I ordered a 520 conversion kit for my Hayabusa 1300R which include Sunstar front sprochet 17 teeth same stock size (stoch with 530 size). The Sunstar front sprocket has super ligh weight, full kit include DID 520 ZVM-X chain 116 link , front sprocket 17 teeth and rear sprocket 43 teeth weight only about 2.5kg, I think I've lost 50 percent of the weight.
