{"product_id":"wilwood-260-4201","title":"Wilwood Left Handlebar Hydraulic Master with Impact-Resistant Long Lever and 5\/8-inch Piston","description":"\u003cp\u003eThis left-hand handlebar master combines a long lever with a translucent integral reservoir and a three-position hydraulic brake lock. Its five-eighths-inch bore is intended for suitable recreational, sport and outdoor equipment rather than an assumed model-specific replacement. The broader Wilwood Engineering range includes calipers, brake lines, rotors, valves, fittings and master cylinders for disc brake systems. Established by Bill Wood in 1977 and based in Camarillo, California, Wilwood designs and manufactures for motorsport, street-performance and specialized applications. Correct component selection considers the complete system's geometry and hydraulic requirements.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 260-4201\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum \/ Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder bore:\u003c\/strong\u003e 5\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure circuits:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length:\u003c\/strong\u003e 0.45 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed displacement per stroke:\u003c\/strong\u003e 0.12 cu in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir Type:\u003c\/strong\u003e Integral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 7.50\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting centers:\u003c\/strong\u003e 7\/8\" Dia.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black E-coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBar diameter:\u003c\/strong\u003e 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLever:\u003c\/strong\u003e Long impact-resistant lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock:\u003c\/strong\u003e Three-position hydraulic holding mechanism\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide:\u003c\/strong\u003e Left hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection references:\u003c\/strong\u003e Exact page identifies M10 × 1.0 banjo and threaded 1\/4-32 switch; FL55 lists M10 × 1.0 inverted double flare and a bayonet switch for this part number.
