Structure Design of Motorcycle Brake Disk
1. The ratio between the outer diameter and rim diameter is expressed as D/d
Front Wheel: 0.4~0.45
Rear Wheel: 0.38~0.42

In general, the rear wheel diameter ranges from 210mm to 250mm. If the motorcycle engine capacity is less than 250cc, then the diameter of motorcycle front wheel ranges from 150~250mm. For the one with the engine capacity of no less than 250cc, the front wheel diameter is from 245mm to 320mm, but the single wheel is available with the diameter ranging from 240mm to 336mm.

2. Thickness of Brake Disc
Front Wheel: a. single type: 6.0~7.0mm; b. double type: 3.5~5.0mm
Rear Wheel: 5~6mm

3. With the ventilation holes designed on the surface, this product has good dissipation, and has been reduced in weight. The friction coefficient has been thereby increased to ensure the braking safety. Also, those holes can help prevent the noise generation, and get rid of the sand between the brake disc and friction liner.

4. Ordinarily, 2Cr13 and 1Cr13 are chosen as the raw materials. 1Cr13 is better than 2Cr13 in corrosion resistance. The hardness is required to be HRC36±3.
