What does motorcycle drafting mean?
2 Answers
Motorcycle drafting refers to the phenomenon where a racing vehicle creates a high-pressure area at the front and a vacuum area at the rear due to airflow separation during high-speed movement. The pressure difference between the front and rear is the primary source of the vehicle's air resistance. When a trailing motorcycle enters the vacuum area formed by the leading vehicle, the pressure difference on the trailing vehicle is reduced, thereby decreasing its air resistance. This allows the trailing vehicle to follow the leading one without fully opening the throttle. Additionally, when the trailing vehicle enters the vacuum area of the leading vehicle, it also affects the formation of the turbulent flow field at the rear of the leading vehicle. As a result, when two or more vehicles travel in a line, their combined air resistance is significantly lower compared to a single vehicle, and the overall speed of the convoy increases compared to a single vehicle.
As a seasoned rider, I know all about drafting! It's basically riding really close behind another vehicle, where the airflow disrupted by the lead vehicle creates a low-pressure zone at its rear. If you get close enough (within 1-2 meters), you'll feel your bike suddenly become lighter and more responsive—no need to twist the throttle all the way to keep up. Fuel savings are guaranteed, cutting consumption by up to 20% on highways. But it demands razor-sharp reflexes; if the lead vehicle brakes hard or swerves, you’ll be performing acrobatics. Plus, kicked-up gravel coats your visor, and rain turns it into a waterfall. I only do this occasionally on familiar roads and only after sizing up the lead driver’s habits. Newbies, steer clear—don’t try this!
