Galfer Rear Wave Rotors




When I checked my rear rotor on my 800GS at approximately 18,000-miles, it was about 1mm away from needing to be replaced (according to BMW specs). I happen to relish the opportunity to bolt new farkles on my bike, but maintaining minimum safety standards is a no-brainer. If safety is good, then more safety is surely better. So, let's take things a step further and add a better performing brake system to the rear wheel. Introducing the Galfer RearWave Rotor for the 800GS.

Our 800GS utilizes the rear brake heavily in a variety of conditions: wet pavement and water crossings, dirt, mud, snow, sand, and desert temperatures well over 100-degrees in the summer. We need a rear rotor that will dissipate heat and fight brake fade while maintaining bite in all of the messy off-road conditions we plow this motorcycle through. Galfer has been a trusted name in brakes for over 50 years, and we?ve used a number of their performance braking applications with great success.

The Galfer Rear Wave Rotor installs without any issue since it's a direct replacement for the stock BMW rotor. Do-it-yourselfers may want to make one note: the brake caliper floats on the carrier as the pads wear to keep each side even on the rotor, so you?ll need to slide the caliper over to fit the new rotor and pads into the caliper. That little trick aside, the installation was about as straight forward as it gets.


The performance on the Galfer Rear Wave Rotor is outstanding. We can pound on the brake pedal all day and it responds beautifully without fail. The rotor sheds water through its self-cleaning properties thanks to the wave shape, which also aids in cooling- paramount to a good rotor. Heat will cause brakes to fade, meaning that they start to feel soft and lose their bite. Galfer has worked tirelessly on solving this problem by actually inventing and patenting the Wave Rotor. Thanks Galfer!
