**The stock size chain cannot be used on vehicles that are set up for conversion, and must be converted to the correct chain size.
*The color and shape of the delivered product may differ from the picture.
*If you change the number of sprockets from the stock, it may not be able to be installed on some models.
*Durability is for reference only.It depends on your riding style, chain size and maintenance condition.
*Offset figures are for sprockets only.
*The actual offset of the chainline from the stock value will vary from model to model.Please note that if the stock sprocket has an offset, that value will be subtracted.(It depends on each model)
*Not all of the available tooth numbers can be installed without interference to the vehicle body.Please confirm the installation of each vehicle body according to the number of teeth by yourself.
*Not all sprockets have lightweight holes.
*There may be changes in product specifications due to the manufacturer's reasons..
* The image is only for reference. The image shown may differ from the actual product.
[Using chrome molybdenum steel casting 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.
[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.
[Convertible front sprocket for racing]
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.

On the interference of Driven Sprocket
When I fit 18 Sprockets, the Chain doesn't fit because the Cover has too much Limit.
Because I made the rear tire thicker, I thought the offset should be larger, so I decided to use it.
I didn't get a call from him so I put a 16T ZEPHYR400 Sprocket on it. There is no picture of it because it is already installed.

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.

Easier and quicker to order from Japan than Europe!
I was very sceptical about ordering via webike however I could not find this particular part anywhere but the USA or Japan. I took the gamble with Japan and I have been very impressed, not only can you track your order whilst it's in Japan but it also works with Royalmail, ordered on the 16, processed on the 17, delivered to my door on the 20th. I don't usually leave reviews and after all this is just a front sprocket but it's Japanese quality not rubbish from their neighbours. Afraid to say it Europe but I'm going to start my searches with Webike first from now on.
