We lightened the rear caliper on the GSF1200 and Bandit 1200.
Earned—I wonder if I’m the only one who noticed that the rear squealing disappeared with this caliper?
Since the rear gets used so much, when you hit the mountain passes or the track you get a “squeaky” sound like a rocket firework.
But after switching to this one, it stopped squealing—though we also replaced the rotor and other parts at the same time, so I can’t say for sure.
Back in the day we used to sandblast these before sending them out for anodizing, but…
Lately we haven’t been able to go that far, so we’re making do with aluminum pistons from the GS1200SS and R1000!
We also swapped the bolts for stainless steel—looks sharp.
The pad pins didn’t have a retainer originally, so we drilled holes and installed pins to keep them in place.
Each piston is 50 grams lighter. Total: 100 grams.
Steel piston: 30 g
Aluminum piston: 80 g
Caliper, pins, and backing plate combined: 615 g.
Yum yum~
