[forged steel FRONT]

Sunstar offers a wide range of offset dimensions. High precision Sunstar sprockets for advanced undercarriage customization.

Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
I replaced it while I was working on the Rear Sprocket. It's hard to evaluate anything because it's not a dramatic change in Parts, but it's a well-known manufacturer, so it's safe to use.View Detail
I installed it in CBR 250 RR MC 51. There seems to be a User who exchanges Rear only Sprocket in an invisible place in Chain Cover, but OEMDriveSprocket of MC 51 is equipped with rigid Rubber for noise reduction. Since this is the resistance of Friction it is strongly recommended to replace DriveSprocket together!View Detail
Purchase for CBR 250 RR MC 51. There is no lightweight hole like the reference image. Weight is slightly lighter than OEM, but that is because it's no soundproof Rubber arriving at OEMSprocket.View Detail
