Especially this time I bought for 520 for Conversion of CBR 1000 RR so I chose trust SUNSTAR.
SUNSTAR is recommended for Sprocket.

**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 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.

For promoting weight saving, mounting SUNSTARS PROTECET.
I was worried about XAM, but I pushed Spot to quality better than Parenthesis and took the step for car inspection. Well, Cover does not see DriveSprocket, but
Just being SUNSTAR makes me happy. I think that performance is also understood by amateurs, but this Quantity : With 1 Set of 3-items, the more you press the Motorcycle, the more it will be decreased. I think that it will probably influence the fuel economy as much as Large.
【What made you decide the purchase?】
Brand Power & Achievements
【How was it actually used?】
Satisfied. There is no dissatisfaction point. It's too light, so I'm worried about LIFE.
【Was it difficult to install? (Hard parts case)】
As it is underbody, I think about safety and leave it at the same time as vehicle inspection.
【Please tell me the point of installation and hang (in the case of Hard parts)】
The labor price may be cheaper if it is with the automobile inspection.
[Is there anything I was disappointed about?]
None
【Hope for Manufacturer - Please let me know if you have any improvement points]
Lack of color variations. Well, I like this color, too.
【Have you compared items?】
XAM
[Others]
I can see the difference. Lol

In changing a Chain size into 520 from pure 530, it equipped.Since change of only a Chain size was used this time [
> ], the folio number was made the same with it being pure.
Although evaluation of a Parts of this sort is a difficult place, I think that it is good, and it is a good product since mounting accuracy did not need strange processing.
