Studies of fatal crashes, insurance claims and test track performance all confirm the importance of antilock brakes.
The rate of fatal crashes is 31 percent lower for motorcycles equipped with optional ABS than for those same models without ABS.
Insurance Institute for Highway Safety, 2013
Collision insurance claims for motorcycles with ABS are filed 20 percent less frequently than for motorcycles without it — 31 percent when the ABS bikes have combined controls.
Highway Loss Data Institute, 2013
On the test track, both new and experienced riders stop more quickly with antilock brakes. Stopping distances improve on wet and dry surfaces alike.

As any rider knows, stopping a motorcycle isn't as simple as stopping a car. Most bikes have separate brake controls for the front and rear wheels, and either wheel can lock up during hard braking. On a car, a lockup might result in a skid. On a motorcycle, it often means a serious fall.
No matter how skilled a rider you are, you can't predict when a driver ahead of you will cut you off, forcing you to brake hard. Road surfaces can be unexpectedly sandy or more slippery than they look.
With ABS, riders can brake fully without fear of locking up. Antilocks automatically reduce brake pressure when a lockup is about to occur and increase it again after traction is restored.
More than 4,000 people died in motorcycle crashes in 2011. It makes sense to cut your risk with ABS.
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.
