MotoGP riders can lean their bikes to roughly 65° from vertical, putting knees, elbows and sometimes even shoulders on the asphalt. For comparison, normal street riding usually happens at far smaller lean angles, while modern sportbikes can mechanically reach roughly 50–55° before ground clearance becomes a major limitation. The faster a motorcycle travels through a given corner radius, the more lean angle it needs to maintain that line. At extreme angles, tire grip, suspension setup, ground clearance and smooth rider inputs all become critical. MotoGP machines combine specialized racing tires, advanced aerodynamics and chassis geometry to operate at angles that would be unrealistic for most road bikes. Riders also hang their bodies off the inside of the bike to manage the combined center of mass and reduce how far the motorcycle itself needs to lean. Seeing a MotoGP bike at more than 60° really shows how far modern motorcycle engineering and tire technology have progressed. Wou...
