The NGage HB 163 and HBS 163 rear brake pads are disc brake pads developed for select Royal Enfield motorcycles where this exact pad shape and specification is required for the rear brake caliper position.

These brake pads are listed by NGage for use on multiple Royal Enfield models that share a common rear brake pad format across the UCE, J-platform, 450cc, and 650cc families. As per the official NGage brake pad compatibility chart, the following motorcycles use pad code HB 163 (Whisker Ceramic) or HBS 163 (Sintered) at the rear:

• Royal Enfield Thunderbird 350 (UCE)

• Royal Enfield Thunderbird 500 (UCE)

• Royal Enfield Classic 350 (UCE)

• Royal Enfield Classic 500 (UCE)

• Royal Enfield Electra 350 (UCE)

• Royal Enfield Electra 500 (UCE)

• Royal Enfield Meteor 350

• Royal Enfield Hunter 350

• Royal Enfield Classic 350 Reborn

• Royal Enfield Himalayan 411

• Royal Enfield Himalayan 450

• Royal Enfield Guerrilla 450

• Royal Enfield Interceptor 650

• Royal Enfield Continental GT 650

This listing covers the rear brake pad set only for the above motorcycles.

Brake pads are a critical safety component in any motorcycle braking system. Their role is to generate friction against the brake disc when hydraulic pressure is applied through the brake caliper. Correct brake pad selection depends on the physical pad shape, backing plate profile, mounting geometry, and friction material specification defined for a given brake caliper design.

The NGage HB 163 and HBS 163 pads are manufactured to match the mounting dimensions and backing plate geometry specified for the rear brake calipers used on the listed Royal Enfield models. These pads are intended as direct-replacement components and are not designed to alter brake caliper geometry, disc size, or braking system architecture.

Pad Code Structure & Fitment Logic

Brake pad codes define the physical shape and mounting interface of the brake pad. Only pads with the exact matching code should be used in a given brake caliper.

For the motorcycles covered under this listing:

• HB 163 corresponds to the Whisker Ceramic variant

• HBS 163 corresponds to the Sintered variant

Both variants share the same physical dimensions, backing plate profile, and mounting points. The only difference between the two is the friction material composition.

Using the correct pad code is essential. Installing brake pads with a different shape or specification may result in improper seating, uneven wear, brake noise, reduced braking efficiency, or brake system damage.

Variant Explanation

This product is available in two NGage material variants:

HB 163 – Whisker Ceramic Brake Pads
Ceramic-based friction compound reinforced with whisker fibers.
Listed by NGage as “HB – Whisker Ceramic Pads.”
Designed for controlled braking feel and stable performance under standard road-use conditions.

HBS 163 – Sintered Brake Pads
Metallic sintered friction compound.
Listed by NGage as “HBS – Sintered Pads.”
Designed for higher thermal stability and consistent braking under sustained load.

Both variants are identical in shape, fitment, and mounting dimensions.
Only the friction material composition differs.

Intended Application & Compatibility Context

The NGage HB 163 and HBS 163 rear brake pads are specified only for motorcycles where this exact pad code is listed in official NGage compatibility documentation.

This listing applies strictly to the rear brake caliper position on the following motorcycles:

• Royal Enfield Thunderbird 350 (UCE) – Rear

• Royal Enfield Thunderbird 500 (UCE) – Rear

• Royal Enfield Classic 350 (UCE) – Rear

• Royal Enfield Classic 500 (UCE) – Rear

• Royal Enfield Electra 350 (UCE) – Rear

• Royal Enfield Electra 500 (UCE) – Rear

• Royal Enfield Meteor 350 – Rear

• Royal Enfield Hunter 350 – Rear

• Royal Enfield Classic 350 Reborn – Rear

• Royal Enfield Himalayan 411 – Rear

• Royal Enfield Himalayan 450 – Rear

• Royal Enfield Guerrilla 450 – Rear

• Royal Enfield Interceptor 650 – Rear

• Royal Enfield Continental GT 650 – Rear

Compatibility applies only when HB 163 or HBS 163 is the recommended rear brake pad specification. Motorcycles using a different pad code should not use this model, even if engine displacement or platform appears similar.

Installation & Service Considerations

Brake pads are routine service components and should be replaced according to the motorcycle manufacturer’s recommended service intervals or when pad thickness reaches the wear limit.

Installation should be carried out following standard brake service procedures, including:

• Cleaning the brake caliper and pad guide surfaces

• Verifying brake disc condition

• Correctly seating the pads in the caliper

• Applying proper tightening torque to mounting hardware

• Performing a bed-in procedure after installation

Improper installation may affect braking performance or cause premature wear.

Professional installation is recommended for riders who are not familiar with motorcycle brake system service procedures.

Summary

The NGage HB 163 and HBS 163 rear brake pads are direct-replacement brake pads designed for select Royal Enfield motorcycles where this exact pad shape and specification is required.

Available in Whisker Ceramic and Sintered variants, these pads provide two friction material options while maintaining identical fitment geometry. Correct specification matching and proper installation are essential prior to use.
