• Sealed reservoir and piston restore pressure and reduce air ingestion into the system.
• Durable materials intended for off-road vibration and exposure.

What are the key dimensions and connection details I need to know?

Critical sizing is provided so you can confirm compatibility before purchase: the clamp fits standard 7/8" (22mm) handlebars, the hydraulic bore measures 14mm, and the thread specification is 10mm. These dimensions are the most common for the compatible Honda ATV models listed.

• Handlebar clamp: 7/8" (22mm) for standard ATV bars.
• Bore: 14mm, matching original master cylinder displacement.

Installation is straightforward for anyone comfortable with basic ATV maintenance: remove the worn master, transfer or replace brake lines, bench-bleed and then bleed the system on the machine. The package contains one front right master cylinder ready to mount and connect.

• Packaged item: one 7/8" front right brake master cylinder.
