Trail braking

From Wikipedia, the free encyclopedia

This article or section is missing information about: trail braking as used in 4-wheel vehicles.
This concern has been noted on the talk page where it may be discussed whether or not to include such information.(March 2008)

Trail braking is a motorcycle riding and driving technique where the brakes are used beyond the entrance to a turn and are gradually released up to the point of apex.

In applying this technique, motorcycle riders approach turns applying both front and rear brakes to reduce speed. As they enter the turn, they partially release the brakes, as to keep only partial brakes throughout the turn. This will give more traction as the front tire is forced into the pavement.

This technique is commonly used when racing, but can enhance control and add more evasive options for street riders making it very worthwhile to learn or at least understand.

Be aware though that excessive trail braking can result in a loss of grip as the tire's adhesion is split between braking and cornering forces. It will also noticeably affect the motorcycle behaviour (as in handling). Should the surface traction be unexpectedly impaired, possibly by oil or fuel spills, a crash is utterly unavoidable.

For a discussion of how this applies more force to the front tire and how much, see Bicycle and motorcycle dynamics.
