There are a couple of reasons that braking on a motorcycle can be challenging. The main reason is that the brakes are not one complete piece. When you hit the brakes on a car or truck, it only takes the push of one pedal to activate the front and back brakes. This is not the case on bikes. When the rider wants to brake, he is required to activate the front and rear brakes independently. If this process is done incorrectly, too quickly, or too slowly, the bike can lose control of its grip with the road. This in turn causes a worse situation than the rider is expecting. Braking can become even more complicated if the terrain is rocky, slippery, wet, or icy. Many experienced bikers have had to learn how to compensate for different situations and terrains depending on where they are riding and when.
