Motorcycle racers and cyclists have different dynamics and capabilities when it comes to cornering and leaning into turns. There are several factors that contribute to the ability of motorcycle racers to lean more significantly than cyclists:
Stability: Motorcycles have a larger wheelbase, lower center of gravity, and are generally more stable than bicycles. This stability allows motorcycle racers to lean further into turns without losing balance. Bicycles, on the other hand, have a shorter wheelbase and a higher center of gravity, making it more challenging to lean too far without the risk of tipping over.
Speed and Inertia: Motorcycle racers typically ride at much higher speeds than cyclists, which provides them with greater centrifugal force and inertia. This centrifugal force helps to counterbalance the lean and allows motorcycle racers to maintain stability while cornering at high speeds. In contrast, cyclists generally ride at lower speeds, and the centrifugal force generated is not enough to lean as significantly without losing balance.
Tire Contact Patch: Motorcycles have wider tires with more surface area in contact with the road. This increased tire contact patch provides greater grip and traction, allowing motorcycle racers to lean more aggressively into turns. Bicycles have narrower tires, and the smaller contact patch limits the amount of lean possible before the tires lose traction.
Body Position: Motorcycle racers often employ a technique called "hanging off" where they shift their body weight towards the inside of the turn. This technique helps to balance the bike and lower the center of gravity, allowing for deeper leans. Cyclists, however, generally maintain a more upright position while cornering, making it more difficult to achieve similar lean angles.
It's important to note that professional cyclists in events such as road racing or track cycling can still achieve impressive lean angles, especially when riding at high speeds. However, the dynamics and limitations of bicycles compared to motorcycles make it challenging for cyclists to lean as dramatically as motorcycle racers do.
