Technical Details

Installation Note

This is a safety-critical braking component and should be installed by a qualified motorcycle technician.

• Inspect the complete master-cylinder bore for scratches, corrosion and pitting.
• Replace the complete master-cylinder assembly if the bore is damaged beyond service limits.
• Use only the brake-fluid specification stated in the vehicle service manual.
• Keep the seals free from dirt, grease, mineral oil, fuel and incompatible chemicals.
• Inspect the reservoir, brake hose, banjo washers and caliper before completing the repair.
• Bleed the hydraulic system completely after installation.
• Check for leakage and firm lever pressure.
• Perform a controlled low-speed brake test before normal road use.

Is this the complete master cylinder?
No. This listing is for the internal Cylinder Set Master. The master-cylinder body, lever and reservoir are not included unless specifically packed by Hero.

Will it fit every Karizma XMR?
No broad all-year claim should be assumed. Confirm the exact production version and part number through the chassis/VIN-based Hero EPC.

Will it fit the standard Xtreme 125R or Xtreme 160R 4V?
The EPC list specifically names Xtreme 125 XTEC2 and Xtreme 160 4V Next. Do not assume compatibility with other versions without exact EPC confirmation.

Can it be matched only by appearance?
No. Similar-looking master-cylinder service sets may differ internally and are not automatically interchangeable.

Does it include brake fluid?
No. Brake fluid is not included.

Can it repair a scratched master-cylinder bore?
Not necessarily. A damaged or corroded bore may require replacement of the complete master-cylinder assembly.

Can this part be returned after opening?
A brake component that has been opened, installed, contaminated or exposed to brake fluid cannot be treated as unused. Confirm compatibility before opening the package.
