The NCY Universal 4-Piston Brake Caliper delivers a significant braking upgrade for scooters, mini-motos, and small-displacement motorcycles running aftermarket brake setups. With four pistons working in tandem, this caliper generates substantially more clamping force than a standard 2-piston OEM unit, translating to shorter stopping distances, improved modulation, and more consistent feel under repeated hard braking. The right-side mounting orientation and universal bracket design make it adaptable to a wide range of custom and aftermarket fork configurations.
- 4-piston design for increased clamping force over OEM 2-piston calipers
- Right-side mounting; universal bracket fitment for custom and aftermarket applications
- Anodized black finish for corrosion resistance and clean aesthetics
- Compatible with standard brake line fittings
- Best paired with the NCY 245mm Floating Disc Brake Rotor for maximum braking performance and thermal stability (may require NCY Caliper Adapter depending on application).Â
- Sold individually; brake line and hardware not included
