Calculation Methodology

Lean Angle θ = arctan(v² / (g * R)). Lateral G-Force = tan(θ). Maximum Adhesion Speed = sqrt(Tire Friction Coefficient * g * R) * 3.6.

Frequently Asked Questions

Standard street tires typically lose adhesion beyond 45° to 50° of lean. Exceeding the tire's friction coefficient causes an immediate lowside crash.
