How about a little ABS information


An antilock braking system works by constantly measuring wheel speed. One common way to do this is with a small grooved ring near the brake disc often called a tone wheel. The wheel speed sensor sends the tone wheel readings to the ABS unit, which can determine whether the wheel is about to stop rotating. If it is, wheel speed information is used to adjust the pressure from the brake cylinder on the brake caliper multiple times per second. This is the equivilent of applying and releasing the brakes multiple times, faster than is humanly possible.

Proven benefits

Studies of fatal crashes, insurance claims and test track performance all confirm the importance of antilock brakes.

Fewer deaths

The rate of fatal crashes is 37 percent lower for motorcycles equipped with optional ABS than for those same models without ABS.
Insurance Institute for Highway Safety, 2011

Fewer crashes

Collision insurance claims for motorcycles with ABS are filed 23 percent less frequently than for motorcycles without it.
Highway Loss Data Institute, 2012

Shorter stopping distances

On the test track, both new and experienced riders stop more quickly with antilock brakes. Stopping distances improve on wet and dry surfaces alike.
