It uses a 3.44-inch direct fork-leg mounting pattern and 1.25-inch stainless pistons. Wilwood excludes Springer and four-speed FL models from the stated front application. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-7736-BK\u003c\/li\u003e\n\u003cli\u003eCaliper type: GP310 Motorcycle Front (1984-1999)\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Black Powder Coat\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.25 \/ 1.25 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 2.46 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.25 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.18–0.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 11.00–11.50 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Lug\u003c\/li\u003e\n\u003cli\u003eMounting side: Right Hand\u003c\/li\u003e\n\u003cli\u003eMounting centers: 3.44 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 2.33 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 3\/8-24\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 6208\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 3.65 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 0.63 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 2.0 lb\u003c\/li\u003e\n\u003cli\u003eSupplied brake components: Individual GP310 caliper with brake pads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify the fork-leg mount, rotor and right-hand orientation before ordering. The selected caliper lists 0.18–0.25-inch rotor thickness and an 11.00–11.50-inch diameter envelope. Check line connection, wheel clearance and the motorcycle’s required fluid specification; the GP310 family’s rear bracket applications do not define this front caliper’s fitment. Wilwood also specifically includes the 1983 Harley-Davidson XR1000 front application; verify the same fork, rotor and mounting requirements.\u003c\/p\u003e\u003cp\u003eWith over 20 years of parts experience, PMB Performance can help compare this component with your existing brake assembly.
