Why do some joint venture Honda motorcycles have to be designed with double drum brakes and front disc rear brakes?

First, analyze the drum brake. Drum brake has simple structure, low maintenance cost and good dustproof effect, but the braking effect is not as good as that of disc brake.

Disc brake. Disc brake has obvious braking effect and looks more beautiful, but the structure is complex, the cost is high and it costs more to maintain.

Advantages of drum brake. In addition to low maintenance cost, the drum brake has strong protection ability and is not easy to be damaged when walking on some muddy and gravel sections.

Advantages of disc brake. Disc brake is a kind of easily worn brake pad, and the maintenance cost of replacing it will increase with the increase of kilometers.

Contrast: Disc brakes have high maintenance cost and are easy to be damaged when walking on some muddy roads; The drum brake has no obvious braking effect, low maintenance cost and is not easy to be damaged.
