When watching a road motorcycle race, those professional riders like to stick their feet out when slowing down into a corner. At this time, their feet have completely left the rear brake pedal. Do they use the rear brake?
Seeing this, some novices or middle-hands or even veterans may be surprised! This subverts many people’s perception of riding habits for many years. How is possible? Some of them began to question. Please don’t get excited here. Let me tell you why. Why do professional riders do not use rear brakes when decelerating? Let us first understand a term that is closely related to it: “engine braking”. That is to say, when the throttle is closed and the gear is downshifted, the engine brake acts on the riding wheels (rear wheels), and the more the gears are down, the greater the braking force. In a motorcycle race, the standard operation of a professional rider to decelerate before each curve is: turn off the accelerator-brake-downshift, this operation just triggers the engine brake.
Of course, there are many benefits for the rider to slow down before entering the corner without using the rear brake:
- Avoid horrible high falls caused by improper operation
Usually when cornering, if the rear brake is accidentally locked, the rear wheel will start to slip. When the rider finds that the rear brake is uncontrollable and dangerous, he will quickly release the rear brake completely in a tight condition. At this time, the rear wheel suddenly resumed its grip, because the rear wheel was slipping, so that the angle of the body and the direction of travel were completely different, so the motorcycle turned violently, coupled with the effect of the shock absorber rebound, and the person was thrown out.
- You can kick out unscrupulously by liberating the right foot.
There are too many benefits of getting out of the foot before entering a turn, such as preventing from getting close to overtaking from behind, increasing wind resistance to help slow down, etc… But personally, I think the biggest effect is to maintain balance. If you have friends who play off-road and road racing at the same time, you may understand that when the rider has to step out to maintain body balance under intense braking and when the rider is in a state of frequent loss of control, then the right foot can completely eliminate the need to step on the rear brake.
- Simplify operations, and concentrate on bends
There is a saying in the racing circuit: the rider who makes the least mistakes can often have the last laugh! And reducing the use of the brake means doing the least things to minimize the chance of error. Riders can concentrate on dealing with sudden situations in the corners during intense riding, and they can also save on physical loss.
- Protect the rear brake so that it won’t fail when really needed
Since the rear brake is installed at the rear of the motorcycle, the ventilation effect is not good, and it will easily cause heat attenuation and damage the brake when used for a long time. I remember when I was off the track at the beginning of the year, because I was used to street riding for a long time, I over-relied on the rear brake to slow down. After a few laps, the rear brake was damaged immediately. When I was confused, a senior rider came over and said to me: The rear brake is used too much when decelerating, but it does not work. I was also taken aback at the time! Having said that, some people may ask, if you don’t need it, why don’t you keep it? In fact, the rear brake has two important functions on the track:
- Suppress excessive head tilt
On the track, in order to pursue the greatest degree of grip, professional riders are trying to restrain their heads. In the event of a high-throttle turning out of a turn, experienced riders do not need to loosen the oil, continue to maintain high-throttle and engine revolutions, and at the same time, by using the rear brake slightly, the front of the motorcycle can return to the ground. If the oil is loosened, it will eventually affect the speed and lap speed.
- Tighten lanes
When the rider enters a corner, if he finds that the accelerator is opened early or the line is running away. For the same reason, the fuel cannot be collected at this time. By just lightly stepping on the rear brake, the direct effect is that the body still maintains the original tilt angle under the circumstances, and the vehicle speed will be reduced slightly, while the lane will be tightened at the same time to solve the problem of “going big”.
Going back to daily riding, the above mentioned so many advantages of using engine braking instead of rear brakes. Although most of us are not racers, we can absorb these useful racing skills and use engine braking to slow down more. Establishing a correct riding habit can make our riding safer and more fun. At present, a considerable number of riders like to squeeze the clutch and slide the motorcycle before the corner, or even slip into the corner, completely resisting engine braking, and proudly say it is for saving fuel. This kind of running habit like a wild horse is very dangerous, and it cannot save too much oil. In case of an unexpected situation, braking vigorously can easily cause skidding. Therefore, I suggest you riders, in daily riding, we can try to experience more, so that the proficient use of engine braking to slow down smoothly, especially on downhill sections, which is the orthodox riding habit.
