The synergistic effect of high hardness by high level quenching and anti-corrosive treatment that does not deteriorate the material boasts excellent durability.When carburizing and nitriding heat treatment is applied to steel materials, it is very difficult to maintain high-precision dimensions because of the different expansion and contraction rates.Sunstar applies a special heat treatment process using its own facilities and technology.

Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
After all, SUNSTAR is the best choice for Sprocket. However, the Driven Sprocket for 520Conversion around yzf-r1 and FZ1 does not have Number of teeth on the OEM. If you are driving on a circuit, you can drop the front one and have no problem at all. If you are driving on a circuit like Tsukuba where top speed does not come out, you can drop the front two; It seems to be the voice from the manufacturer that says don't do the conversion in the street in the first place, but Number of teeth on the OEM has no choice but to choose another company's product. Even for touring use, if it's just one drop, there's no negatives there, and if you don't have to cruise at high speeds, the Merit will be easier to start. However, I don't recommend dropping two guns because I think it will cause more negatives on public roads.View Detail
【What made you decide the purchase?】 ? I decided to change it as SUNSTAR, so I purchased 520 Size for Conversion
【How was it actually used?】 ? Unlike STDSprocket, since there is no muffler Rubber, I thought that the running noise would become bigger, I thought I'd run Motorcycle and I listened carefully, but I feel like I got annoyed ... ? Although it became lighter weight of about 100 g, it does not understand the difference with DriveSprocketSingle Body
【Mounting was difficult?】 ? Installation is a simple task of removing Nut and exchanging Sprocket, but because it is tightened with a high Torque and locking agent is painted, Tire will run idle just by turning it normally
【Please tell me the installation point and hang】 ? If you use Impact or work with two people, you can exchange it somewhat easier, but in the case of work by one person, you multiply Brake over Motorcycle and use Long Spinner Handle ? Because Nut is Crimp in two places, I will raise it with 100 Precision Driver
[Is there anything I was disappointed about?] ? Because there are many weight reduction holes, there is no stamp of company name or number of teeth. Although it is a place hidden by Cover, I feel a little sad
【Hope for Manufacturer ? Please let me know if there are any improvement points] ? For Conversion 520 Size, 15T, 16T, 18T and 17T have not been lineuped, so 17T with the same number of teeth as STD is also requested
【Have you compared items?】 ? DRIVEN : Front sprocket
[Others] ? In the case of R1, Nut can not be reused because it crimps after tightening. Purchasing with SprocketView Detail
