COMPATIBILITY CALCULATIONS FOR DOUBLE DISC MASTER

 

Please check the caliper piston diameter of your vehicle.
Calculated results are data based on theoretical values. It may not be possible to install depending on motorcycle conditions and vehicle type.
For actual feeling and installation, please consult a specialized motorcycle store.

※ The above is reference information based on theoretical values.
The lower the number, the harder and shorter the stroke.
The larger it is, the softer and longer the stroke.
Total ratio 90-115 is recommended for street.
