In the high-speed world of MotoGP, body positioning plays a crucial role in a rider’s success on the track. One of the most distinctive techniques employed by MotoGP riders is sticking their knee out while cornering. This technique, popularized by the legendary Valentino Rossi during his epic pass on Sete Gibernau at the Jerez circuit in 2005, has become a hallmark of modern MotoGP racing.
The primary purpose of the knee-out technique is to aid in braking and cornering. By extending their leg and knee, riders create additional aerodynamic drag, effectively slowing the bike down, much like a parachute. This allows for more precise and controlled braking before entering a turn. Additionally, the knee-out position helps to shift the rider’s weight and balance on the bike, enabling them to lean the motorcycle more aggressively and navigate corners at higher speeds.
“The knee-out technique is not just about style; it serves a crucial purpose in managing the bike’s speed and stability during cornering. By creating aerodynamic drag and shifting the rider’s weight, it allows us to push the limits of what’s possible on the track.” – Marc Marquez, 8-time MotoGP World Champion (Source)
The Evolution of MotoGP Riding Techniques
The world of MotoGP has witnessed a significant evolution in riding styles over the years, with advancements in motorcycle technology and rider equipment playing a crucial role in shaping these changes. In the early days of Grand Prix racing, riders adopted a more static riding position, focusing on minimizing their body movements to reduce aerodynamic drag. However, the late 1970s saw a paradigm shift in riding techniques, largely influenced by the innovative approach of Finnish rider Jarno Saarinen and popularized by American racing legend Kenny Roberts.
Historical Changes in Body Positioning
The static riding position of the early days gave way to a more dynamic approach, with riders actively shifting their weight and leaning their bodies to optimize cornering performance. Kenny Roberts, inspired by Saarinen’s unconventional style, began to hang off the bike, using his knee as a pivot point to guide the motorcycle through turns. This technique revolutionized the way riders approached corners and laid the foundation for the modern MotoGP riding style.
Introduction of the Knee Out Technique
The year 2005 marked a significant milestone in the evolution of MotoGP riding techniques, with Valentino Rossi’s unforgettable overtake on Sete Gibernau at the Jerez circuit. Rossi’s innovative use of the knee-out technique during this maneuver not only stunned spectators but also set a new standard for cornering precision. By extending his leg and knee towards the apex of the turn, Rossi demonstrated the benefits of shifting body weight and balance to optimize the bike’s turning capabilities.
The knee-out technique allows riders to feel the limits of their tires and the track surface, providing crucial feedback and confidence when pushing the boundaries of adhesion. This tactile connection between the rider and the track has become an essential aspect of modern MotoGP racing, enabling riders to extract maximum performance from their machines.
Aerodynamic Benefits
The aerodynamic advantages of the knee-out technique play a significant role in the success of MotoGP riders. By extending their leg and knee, riders create additional drag, which aids in slowing the bike down before entering a corner.
Creating Aerodynamic Drag
At the high speeds encountered in MotoGP, typically exceeding 300 km/h (186 mph), the aerodynamic drag force generated by the rider’s extended leg becomes significantly more pronounced. This increased drag acts as an air brake, helping to decelerate the bike more effectively before the rider initiates the turning process. The controlled deceleration allows for smoother and more precise corner entry, reducing the risk of overshooting the turn or losing control of the bike.
Impact on Speed and Control
In addition to its braking benefits, the knee-out technique also enhances cornering control. By shifting the rider’s weight towards the inside of the turn, the technique helps to counteract the centrifugal force acting on the bike. This allows the rider to maintain a more upright body position, placing more weight on the front tire and improving overall grip and stability.
The knee-out technique, pioneered by Kenny Roberts and refined by subsequent generations of MotoGP riders, has become an essential skill in the modern era of motorcycle racing. It enables riders to optimize their body position, maximize cornering speed, and adapt to the ever-changing conditions on the track, ultimately leading to faster lap times and improved race performance.
“The knee-out technique is not just about aerodynamics; it’s about finding the perfect balance between the rider and the bike. By using our body weight to control the motorcycle’s behavior, we can push the limits of what’s possible in the corners.” – Valentino Rossi, 9-time MotoGP World Champion (Source)
Enhancing Cornering Dynamics
The knee-out technique has emerged as a crucial skill in MotoGP, revolutionizing the way riders approach corners and manage the complex dynamics of high-speed motorcycle racing. By effectively manipulating the center of gravity, optimizing lean angles, and counteracting centrifugal forces, riders can navigate turns with unparalleled precision and control.
Shift in Center of Gravity
One of the primary benefits of the knee-out technique is its ability to facilitate a significant shift in the rider’s center of gravity. By extending the leg towards the inside of the turn, the rider effectively moves their body mass closer to the apex, counteracting the centrifugal force that tends to push the rider and bike towards the outside of the corner. This shift in weight distribution enhances the motorcycle’s stability and allows for more aggressive cornering maneuvers.
Improvement in Lean Angle
The knee-out technique also plays a crucial role in optimizing lean angles during high-speed cornering. By hanging off the side of the bike and extending their leg, riders can maintain a more upright position, reducing the lean angle of the motorcycle itself. This allows for better tire grip and improved cornering speed, as the bike’s suspension can work more efficiently when the motorcycle is not leaned over to its maximum angle.
Interaction with Centrifugal Force
Centrifugal force is a significant challenge that MotoGP riders must contend with when navigating corners at high speeds. As the motorcycle leans into a turn, centrifugal force acts to push the rider towards the outside of the corner, making it more difficult to maintain the desired trajectory. By employing the knee-out technique, riders can effectively counteract this force, using their body weight and position to maintain balance and control throughout the corner.
Preventing Inside Overtakes
In the highly competitive world of MotoGP, riders must employ every available advantage to maintain their position on the track and fend off rivals. The knee-out technique has proven to be a valuable tool in preventing inside overtakes, a strategy that gained significant attention following Valentino Rossi’s iconic move at the Jerez circuit in 2005.
Psychological Impact on Rivals
The use of the knee-out technique during overtaking maneuvers serves not only a functional purpose but also a psychological one. By aggressively extending their leg towards a rival rider, MotoGP competitors can assert their dominance and discourage attempts to pass on the inside. This visual display of confidence and control can have a significant impact on the decision-making process of other riders, making them less likely to attempt a risky overtaking maneuver.
Physical Barrier and Space Reduction
In addition to its psychological effects, the knee-out technique also creates a physical barrier that makes it more challenging for rival riders to pass on the inside of a corner. By occupying the space closest to the apex, the rider employing the knee-out technique effectively reduces the available room for an overtaking maneuver. This space reduction, combined with the shift in the rider’s weight distribution, can significantly hinder the ability of other riders to execute a successful pass.
The Influence of Valentino Rossi
The widespread adoption of the knee-out technique in modern MotoGP racing can be largely attributed to the influence of the legendary Valentino Rossi. His innovative use of the technique during the iconic pass on Sete Gibernau at the Jerez circuit in 2005 showcased the potential benefits of extending the leg during cornering and overtaking maneuvers.
Introduction at Jerez 2005
Rossi’s memorable overtake on Gibernau at the 2005 Jerez race showcased the effectiveness of the knee-out technique in a high-pressure situation. By extending his leg and knee towards the inside of the corner, Rossi was able to optimize his braking performance, shifting his weight forward and creating additional aerodynamic drag to slow the bike down more effectively.
This maneuver not only allowed Rossi to execute a successful pass but also demonstrated the potential of the knee-out technique in enhancing a rider’s control over their motorcycle. By leveraging the shift in weight distribution and the increased feedback from the tires, Rossi was able to navigate the corner with exceptional precision, setting a new standard for cornering technique in MotoGP.
