ISR 4 piston ultralight rear brake caliper

The ISR 4 monobloc 4 piston caliper designed for a two caliper system for 125cc motorcycles, is compatible with all Yamaha and BMW caliper holders.

Due to the low height of 27mm in the area of the washer, this and thus the whole caliper can be greatly lightened.
