No, not all motorcycles have two separate brake levers—one for the front brake and one for the rear brake. The braking system setup can vary depending on the motorcycle model and design. There are generally two types of brake systems used on motorcycles:
Dual Disc Brake System: Many motorcycles, especially larger or sport-oriented ones, are equipped with a dual disc brake system. In this setup, there are two separate brake discs, one for the front wheel and one for the rear wheel. Each disc is operated by its own brake caliper, and typically there are two separate brake levers—one for the front brake and one for the rear brake.
Single Disc Brake System: Some motorcycles, particularly smaller or more basic models, may have a single disc brake system. In this setup, there is a single brake disc, usually at the front wheel, which is operated by a single brake caliper. These motorcycles often have a single brake lever that controls both the front and rear brakes. When the lever is squeezed, the braking force is distributed between the front and rear wheels.
It's important to note that the majority of motorcycles have a front brake lever regardless of the braking system setup. However, the presence or absence of a separate rear brake lever depends on the specific motorcycle model and its brake configuration.
