Steering ratio

From Wikipedia, the free encyclopedia

Steering ratio refers to the ratio between the turn of the steering wheel (in degrees) or handlebars and the turn of the wheels (in degrees). In motorcycles and bicycles, the steering ratio is always 1:1, while in most passenger cars, it is between 12 and 20:1. Example: If one complete turn of the steering wheel (360 degrees) causes the wheels to turn 24 degrees, then the ratio is 15:1 (360/24=15).
