Refresh the handlebar cockpit and stop weeping around the reservoir with the genuine Royal Enfield 1030050/D Master Cylinder Cover. This is the front brake reservoir cap used on Interceptor 650 (BS6/Euro 5). Being OEM, it matches the factory screw spacing, sealing lip, and finish, so it sits perfectly flat on the ByBre master cylinder, compresses the diaphragm evenly, and resists vibration and fluid misting. Cheap pattern caps often have off-spec machining or soft plating that warps or stains—causing leaks and a messy lever perch.

Use this cap whenever the original is scratched, bent, warped from over-tightening, or if you’re restoring the bike to stock after a repaint. Reuse your existing diaphragm if it’s supple and undamaged; replace if it’s swollen or torn. Two JIS screws secure the cap—tighten evenly and avoid over-torque. This listing is restricted to the Interceptor 650 BS6/Euro 5 because that compatibility is explicitly shown on the Royal Enfield spares portal (see your screenshot). If you have a different year/spec, share your VIN and we’ll confirm the exact code before dispatch to reduce returns.

FAQs

Q1. Is this for the front or rear brake?
