Brembo 108mm M4 Cast Monoblock Caliper Set – Front, Titanium Gray/Red

The Brembo 108mm M4 Cast Monoblock Caliper Set delivers race-proven stopping power for street and track riders who demand the best. Machined from a single piece of ultra-light cast aluminum, the M4's monoblock construction maximizes rigidity while minimizing weight — just 800g per caliper without pads. Precision hydraulics and a sculpted caliper body combine for extraordinary braking feel and consistent performance under competitive conditions. This front caliper set ships complete with brake pads, banjo bolts, and crush washers, ready for bolt-on installation on most motorcycles using 108mm (bolt-to-bolt center) calipers.
