then why marquez shakes his hand after releasing the brakes why rossi pushes his upper body even further down in the middle of the corner why mcallister pushes the bike down going into the corner but then leans his upper body forward the corner at the exit because pierce is pulling the clutch until the corner because in mining apply the rear brake in the middle of the corner finding out what professional drivers do in the corners by watching them go at full speed can be very difficult almost impossible even for someone with a trained eye wat especially because riders use different techniques for different corners and situations we also have to consider that different riders within the same racing classes use various styles this is especially true in supermoto where you will see some riders pushing the bike with the stand out while others are left hanging then there are those like me who mix all styles I am sure that a beginner who sees me race on a supermoto track will be very confused so that anyone can understand the answers to the questions posed to the At the beginning of the video there are some concepts that need to be understood when it comes to cornering technique and chassis geometry so I am going to answer the questions by walking through a basic corner step by step these steps apply to

superbike racing and sections of supermoto asphalt to keep things simple the curve we are going to see is at the end of a straightaway this is an important assumption because it affects the position of the rider's body and the state of the bike's chassis when moving towards the curve step 1 configuration before entering the braking zone the pilot has a forward body position to minimize aerodynamic resistance and maximize his maximum speed the pilot accelerates hard which extends both the front and rear suspension the front extends by the load transfer the rear extends through the geometry of the chassis so the swingarm has an angle that could be said to force the rear wheel under the bike when accelerating plus the chain pulls the axle at an angle that adds this force this is called anti es water and the chassis is designed that way so that the rear suspension does not run out of travel when accelerating due to the way the swingarm rotates extending the rear suspension will decrease the overall wheelbase of the motorcycle this will decrease the stability of the motorcycle which is not necessarily a desirable thing but a trade-off one might be willing to make in order to obtain the anti squat feature using a simple geometry when the front forks extend this increases the footprint of the motorcycle which increases the total stability of the motorcycle in this state the motorcycle is very stable but it also requires more force for steering if you want a more in-depth explanation of the geometry of the motorcycle watch my video on the subject right here well then the rider is in the bike accelerating hard the bike is as stable as it can be before or at the beginning of entering the braking zone the rider will prepare for the curve what this means is that they are positioning the lower and upper part of their body to enter the curve the The reason the rider prepares before the turn is to keep the bike as stable as possible as soon as the front brakes are activated the load will be transferred forward which will compress the front forks decreasing the travel this makes the bike is unstable but easy to steer moving the body when on the brakes also requires significant physical effort from the motorcyclist in addition to being hard on the brakes the motorcyclist will push his hands on the handlebars therefore may be giving the motorbike an incorrect direction desired if you move too much when braking a super moto rider pushing the bike underneath them sometimes called motocross style will move their butt out and forward on the bike this puts them on top of the bike which does easier to control and avoid sliding you will see some drivers sitting on the tank in this way they transfer the load to the front tire which will give them more traction in the front and less in the rear if you want a more in-depth explanation of tire traction Watch my video on the subject right here you will see that when the rear slides the front wheel will naturally counteract the steering even without the driver's intervention this is due to the trajectory of the front fork and something called the self-aligning torque of the tire Front self-aligning torque is created by something called pneumatic trace which is caused by progressively building lateral force along the length of the contact patch such that the lateral forces are greatest towards the rear of the contact zone don't worry if you don't understand exactly what trail tires are I scratched my head for a long time about this what you have to understand is that to have maximum control over the front wheel it is easier to sit on top of the bike with your elbows up as opposed to hanging on the inside of the bike step 2 start braking and slow down as soon as the rider releases the accelerator start braking pull the clutch and downshift to the appropriate gear for the curve when and How the clutch is released is very important because this controls the amount of engine braking applied to the rear tire step 3 I will turn the rider turn into the corner by counter-steering or by applying quick torque to the handlebars in the opposite direction. the curve the movement of the front wheel around the steering head generates a lateral force of the front tire which has the effect of leaning the motorcycle towards the curve in addition the gyroscopic effect generated by the front wheel and the rotation of the steering causes a moment gyroscopic which also helps lean the bike into the turn so the rider leans even with the brakes using what is called current breaking where the brakes are gradually released into the turn remembering what happens to the chassis when the front brakes are applied the front forks compress and the rear suspension extends what would happen if the front brakes are suddenly released the front forks will extend making driving more difficult as the trail increases it will transfer the load to the rear tire decreasing the pull on the front Furthermore the movement of the front fork extension will destabilize the entire bike if a rider does not brake the trail will go into the corner as if it were in a bit of a stieg bouncing from one side to the other now that is certainly not a desirable way to enter in a corner at high speed right so the rider is moving towards the apex remember I mentioned that when the clutch is released is very important you have probably seen riders backing up where the rear wheel comes out in a slide the slide is caused by two important things one the weight is transferred forward caused by the application of the front brake and the rider moves forward which makes the rear wheel light 2 the rear wheel is slowed down by engine braking the application of the rear brake or both at the same time the engine braking can be controlled by modulating the clutch in other words the rider can control when the rear wheel slips by operating the clutch nowadays almost all modern racing bikes come standard with something called a slipper clutch which allows the rider to release the clutch quite quickly without the rear wheel jumping so some riders release the clutch completely before entering the corner sometimes they don't release it completely and now we get to answer one of the questions posed at the beginning of the video because pierce he's pulling the clutch all the way into the corner you know the answer to the question he's not controlling rear slip by modulating the clutch and working the rear brake in fact we can see he's releasing the rear brake at exactly the same time as the leader the clutch here is a racer going through the same corner using both the engine brake and the rear brake fully releasing the clutch before the turn so why choose one over the other it all comes down to the rider's personal preference using the clutch gives more direct control over the slide compared to just releasing the clutch this is because if you pull the clutch and release the rear brake the slide will stop therefore a rider who is already pulling the clutch can regain traction much more faster than a rider who has to reach for the clutch and pull it the disadvantage of using the clutch and rear brake is of course that it requires a lot of the rider to control all of that at the same time if the rider uses a supermoto riding style they will move the upper part of his body with the bike as he leans into the corner basically diving in step 4 half corner the rider moves towards the apex of the corner gradually releasing the front brake as soon as the front brake is released the rider starts to turn the accelerator then by burning you shake your hand after releasing the brakes good for two reasons to be able to precisely control the throttle input 2 to be able to move your right elbow freely look if you don't change your grip around the handlebars it would lock your elbow in a way that would not allow her to move freely if she turns left she will extend her arm over the tank if she turns right she will push her elbow into the turn this brings us to the question why rosie pushes her upper body even further down in the middle of the corner then why are you doing this well it's simple this reinforces your line which means you accelerate more and exit faster when a rider hangs on the inside of the bike this transfers their combined center of gravity and of the bike allowing for a smaller lean angle at the same speed if the lean angle remains constant but the rider moves their upper body even further towards the corner tightening their line if they are on the throttle will allow them Keep the bike as straight as possible during this crucial part of the corner so ladies and gentlemen I know you've been waiting for Miller to apply the rear brake mid-corner let's take another look at the chassis geometry at this point of the corner the rider is releasing the front brake this will transfer the load to the rear which is good as the rider will soon apply the throttle which will require traction from the rear tire this will also increase the travel further stabilizing the bike although also we must remember that when the front brakes were applied the rear suspension was extended which decreased the wheelbase and the rear suspension is potentially so extended that it will not follow the bumps as efficiently it is out of its optimal range what can an expert driver do about this well you can drag the rear brake you will see by dragging the rear brake the rear suspension stays controlled and the wheelbase is extended which stabilizes the motorcycle they are dragging the brake enough to cause this change in geometry but not enough to brake in to a large extent so when they release the front brake and increase the travel they now have a chassis geometry that works well to accelerate and exit the curve great no step 5 exit the driver smoothly adds more acceleration when exiting the curve in the style of Driving a super bike to be able to get out of the corner as much as possible the rider stays inside the bike and does not follow it this is simply having a small amount of lean as possible allowing for greater acceleration in a racing style of riding. pure motocross the rider stays on top of the bike and straightens with it in the dirt the bike slides as there is not much pull then because mcallister pushes the bike down going into the corner but then tilts the top of your body into the corner at the exit you are combining motocross and superbike riding styles to get through the corner as quickly as possible you are pushing the bike down as you enter the corner to control the rear end sliding but At the exit it wants the smallest lean angle possible to maximize corner exit so it leans inwards when the accelerator goes up I hope that today you have learned something and that this inspires you to look more at the driving technique and dynamics of the motorcycle feel free to question any of my statements in the comments section below that's all for today over and out with the heart bye
