The extra lever near the left brake on Honda and other mopeds is commonly known as the "left-hand lever" or "combined braking system (CBS) lever." It is a feature designed to enhance the braking performance and safety of the motorcycle.
The left-hand lever operates the front and rear brakes simultaneously when squeezed, providing balanced braking force to both wheels. This helps to distribute the braking power evenly and reduces the chances of skidding or losing control during emergency braking situations.
The CBS lever is particularly beneficial for riders who may not be accustomed to using both front and rear brakes simultaneously. It helps to mitigate the risk of locking up the front or rear wheel due to over-application of one brake, which can result in loss of stability and control.
By combining the braking forces from both wheels, the CBS lever can shorten the braking distance and improve overall braking performance. It promotes a more stable and controlled braking experience, especially for less-experienced riders or in situations where quick and precise braking is required.
Overall, the addition of the left-hand lever or CBS lever in Honda and other mopeds aims to enhance the safety and braking capabilities of the motorcycle, providing riders with improved control and confidence on the road.
