GP Crab King brake calipers are compatible with motorcycles, bicycles, and karts. They are upgraded front and rear disc brake calipers with opposing pistons.

Universal design for various models: The GP Crab King series brake calipers feature a universal interface suitable for disc brake systems on various types of motorcycles (small displacement), high-performance motorcycles (such as e-bikes and downhill bikes), and go-karts. Classic design with opposing pistons: Thanks to the characteristic arrangement of laterally opposed pistons (usually dual pistons), reminiscent of crab claws, the brake calipers are compact and offer consistent braking power. Compared to single-piston calipers, they offer superior braking linearity and heat dissipation while requiring relatively little space. Suitable for front and rear brakes: Thanks to the universal bolt pattern and flexible design, this product can be used to retrofit front or rear disc brake systems, depending on the vehicle-specific mounting (adapter). Significantly improved braking performance: Designed as a replacement for unsuitable original brake calipers, this product effectively improves braking performance, feel, and heat resistance.
