Wilwood 260-4202 Handlebar-Mount Master Cylinder with Lever, Right Side, 5/8-Inch Bore

The Wilwood 260-4202 master cylinder is designed for right-side handlebar mounting on powersports and custom applications. This complete kit includes an integrated lever and reservoir, providing a practical hydraulic control solution for compatible brake or clutch systems. Its 0.625-inch bore and 0.45-inch stroke support precise fluid displacement and responsive lever feel when properly matched to the caliper or slave-cylinder requirements.
Constructed with an aluminum and plastic body, the master cylinder balances durability with a lightweight design. The integral reservoir simplifies installation by combining the fluid container and hydraulic control assembly in one compact unit, helping reduce the need for separate reservoir components. The handlebar-mount configuration is intended for 5/8-inch handlebars and places the controls within easy reach of the operator.
The Wilwood 260-4202 kit is suitable for builders, fabricators, and replacement applications requiring a right-side master cylinder with an included lever. Verify handlebar compatibility, hydraulic line connections, fluid requirements, and system bore sizing before installation. Professional installation and proper bleeding are recommended to help ensure consistent operation and safe system performance.
