Comparing bends on a level road at the same speed under equivalent conditions, which change requires more inward motorcycle lean?

Correct answer

A decrease in bend radius with the other conditions unchanged.

A smaller radius, meaning a tighter bend. Required lean also depends on speed: this is not an instruction to increase lean in every tight bend without first adapting speed. Reduce speed and prepare your path before entering according to visibility, grip and your ability, keeping both motorcycle and body within your lane. In the bend, use the throttle smoothly to maintain control; avoid sudden acceleration or braking. A narrow tyre does not alone determine the required lean.
