Motorbike racing is a sport that is quite extreme, where the driver will compete to win first place to occupy the top of the podium. Like asphalt track racing, motocross racing also has to pass a certain racing line in order to get through the track in the shortest possible time.
The difference is, the racing line referred to in motocross is not the innermost side of the corner like racing on asphalt. However, the most decisive racing line is the way to get through the obstacle or obstacles the racers do. Usually motocross racers are given several choices in passing obstacles.
For example, if there are three hills that are not too far away, the first choice of the racer can be directly over the obstacle in one jump. Or the second option is not too strong, the racer can still go by sticking to the ground to pass the three hills.
It can also just jump over the two hills and the last hill is skipped by jumping or staying attached to the ground. Which of course is more effective between the first, second, and third methods? Actually it all depends on the track, before the hill the racer can make it first or not, the size of the hill is big or small, and many other factors.
Supporting Factors for Successful Jumping of Motocross Racer
The speed of the racer must be precise, it cannot be more or less. Of course, if the jumps don’t reach the target, if it’s too much, it will pass the tracks that have been provided. So the speed must be calculated by the distance between the two hilltops, including the angle of inclination of the hill
The motion of the dirt bike jumping over the hill is a parabolic motion in physics. For example, we assume the height of the top of the hill is the same. The distance between the two hilltops is 10 m, the angle of elevation of the jump hill is 45 degrees, what is the optimum speed for the motorbike to pass through the hill?
where x = distance between two hills, A = elevation angle, Vo = initial velocity, g = acceleration due to gravity (9.81 m / s2). By using the formula for the motion of the parabola above, the initial velocity is found to be 35.65 km/hour.
Motocross Racer Jump Technique
So the racer has to jump at that initial speed for the jump to be perfect. Professional motocross racers (eg MXGP racers) do not calculate in detail how fast they jump. Of course, with practice and experience, they do not need to calculate in detail because they already understand the estimated speed of passing an obstacle. So they will estimate the speed of the motor when it will jump over an obstacle.
That is the most important motocross riding technique to know so that you can train so that the performance of motocross stunts can be maximized. Besides that, the weight of the body must be correct, in general, the weight of the body when sitting is on the spine, right? However, this does not apply to motocross action because it is considered dangerous for the health of the riders and is also able to make the body feel tired more easily.
For the position of the most correct body weight support is to divide it in both hands where the body is positioned slightly bent forward, while the hands can be bent slightly where another term is arrogant style. The head must be in an upright condition and continue to look forward while the position of the feet must be clamping the tank.
Tips for Facing Rocky Tracks
Rocky Track When you encounter a track full of rocks, the important thing to do is position your hands to bend a little so that the shocks felt by the body can be properly damped and motocross action is not disturbed.
You also need to pay attention to weight bearing, that is, you can put your weight on the rear wheel while also trying to be in a standing position. Not only that, riders also need to remember carefully not to do it in a sitting position because the risk of danger is higher and greater.
Descent Not only a steep incline, every rider also needs to face a steep descent which is the opposite of the incline. When going through a sharp drop, the rider needs to position his body slightly back and make sure it is also still in a position on the seat.
Play the rear brake occasionally while wearing low gear. The braking for a type 4 motorbike cannot be done by the rider via the engine brake. In this case, of course, training is also needed so that when you cross the descent, you are used to and in controlling the speed more perfectly.
