The Brembo P4 30/34 is a two-piece CNC billet radial caliper from Brembo's Racing Line, built around four stainless steel pistons (two 30mm, two 34mm). It mounts on 108mm bolt spacing with a 22.5mm offset and a hard anodized finish, and it ships without pads. It is a common choice for supermoto racers and converted dirt bikes, where the staggered piston sizes and rigid billet body give firmer, more consistent lever feel than a cast axial caliper. It pairs naturally with a Brembo RCS-15 master cylinder and a 320mm supermoto rotor; bikes with axial fork bottoms need a radial adapter bracket.
