Tuck (aerodynamic riding position)

A tuck is the crouched position in which a rider lies on the tank behind the windscreen, with elbows and knees pulled in and the head low. It reduces the frontal area exposed to the wind, which lowers drag, increases top speed and reduces fatigue from wind pressure.

Racers tuck on every straight, then sit up just before the braking point so their body acts as an air brake and they can see clearly. On sports bikes the riding position is designed for it; on naked bikes a short tuck can still help on a windy motorway stretch.

Make sure your helmet and leathers allow you to see properly in a tuck, keep your eyes looking forward over the screen and do not stay tucked when you need to watch traffic.
