Braking Styles On Motorcycles - Code Break
Up To SpeedBraking, it turns out, does much more than just slow you down. Fork flex, geometry changes, tire deformation and a host of other forces come into play, drastically affecting the way the motorcycle negotiates a corner. The forward pitch of the bike under braking can steepen the fork angle by as much as 4 degrees on a Ducati 1098, for example. This reduces trail by roughly an inch on the same hypothetical 1098, and effectively shortens the wheelbase as well. Front-wheel load can double under heavy braking. Tire height shrinks under load, further decreasing trail by a slight amount. At the same time, however, the contact patch both broadens and lengthens rearward, which can restore trail by as much as 1 inch. Trail is now close to where it started, unless the tire locks up-at which point you'd have very little stability, owing to an instant reduction of trail. Braking doesn't sound so simple anymore, does it? Photo Gallery: Braking Styles On Motorcycles - Motorcyclist Magazine Read More | Digg It | Add to del.icio.us Click here for full story...
