Why Upgrade to a Radial Caliper?

Radial-mounted brake calipers offer a more direct, rigid connection to the fork leg compared to traditional axial mounts. This reduces flex under hard braking, giving the rider a more precise, feedback-rich feel. The 4-piston opposed design distributes braking force evenly, helping maintain consistent performance lap after lap or mile after mile.

Frequently Asked Questions

Q: What motorcycles is this 484 radial brake caliper compatible with?

A: This caliper is designed for motorcycles with a 100mm radial front brake mounting pattern. It is commonly compatible with sport bikes, naked bikes, and custom builds that use radial caliper mounts. Always verify your fork's mounting distance and thread specifications before ordering.

Q: What is the advantage of a 4-piston opposed caliper over a 2-piston caliper?

A: A 4-piston opposed caliper applies clamping force from both sides of the brake disc simultaneously using two pistons per side. This results in more even pad wear, better modulation, and firmer, more consistent braking feel compared to a sliding 2-piston design — making it a popular upgrade for performance-focused riders.

Q: Is this caliper compatible with standard brake lines and fluid?

A: Yes. The caliper includes a golden oil pipe screw fitting designed for use with standard motorcycle brake line banjo bolts. It is compatible with standard DOT-rated brake fluid. Always ensure brake lines and fluid are rated appropriately for your system.

Q: Does this caliper come ready to install?

A: Yes. The package includes the caliper, mounting screws, oil pipe screw, clip, and an instruction manual. You will need to source a compatible brake disc and brake pads separately if not already fitted to your motorcycle.
