Buy the Hero Genuine Rear Brake Disc / Rear Disc Plate for Hero Karizma ZMR with exact part number 43251KRY971S. This OEM rear brake rotor ensures correct fitment, reliable stopping and long service life—ideal for restorations and proper brake maintenance using genuine Hero packaging.

DETAILED DESCRIPTION 

The rear brake disc (rear disc plate / rear disc rotor) is the rotor mounted on the rear wheel that works with the brake caliper and pads to slow your bike safely and consistently. If your Karizma ZMR’s rear disc is scored, warped, vibrating under braking, or causing uneven pad wear, replacing it with the correct OEM part is critical.

Hero Genuine 43251KRY971S is listed as “DISK, RR BRAKE” and is intended for Karizma ZMR (Sep 2009) fitment. Using an OEM rotor matters because brake parts are safety-critical: genuine parts help maintain proper rotor alignment, correct mounting and predictable braking feel—especially important on higher-speed motorcycles like the Karizma platform.

For customers searching locally, this part is also commonly asked as rear brake disc / rear disc plate / rear disc rotor (rear “disk plate”). Order by part number 43251KRY971S to avoid incorrect aftermarket match-ups.

Under The Hood supplies genuine Hero parts with proper packing and careful dispatch, helping you avoid duplicate/local parts and fitment surprises.
