The NGage HB 155 and HBS 155 rear brake pads are disc brake pads designed for Royal Enfield motorcycles that use this exact pad shape and mounting specification at the rear brake caliper.

These brake pads are specified for the Royal Enfield Super Meteor 650 and Royal Enfield Shotgun 650 in the rear brake position. Both motorcycles share the same rear brake pad format, allowing a single pad code to be used across both models.

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

Brake Pad Function & Fitment Logic

Brake pads are a core wear component in a motorcycle’s braking system. Their role is to generate friction against the brake disc when hydraulic pressure is applied through the brake caliper. For proper braking behavior, brake pads must match the exact backing plate shape, thickness, and mounting profile specified for the brake caliper design used on the motorcycle.

NGage brake pad codes define this physical geometry. Only pads with the correct code should be installed in a given caliper.

For the motorcycles covered under this listing:

• HB 155 represents the Whisker Ceramic variant

• HBS 155 represents the Sintered variant

Both variants share identical dimensions and mounting features. The only difference between the two is the friction material composition.

Using the correct pad code is essential. Installing pads with a different shape or specification can lead to improper seating, uneven pad wear, brake noise, inconsistent braking response, or long-term damage to braking components.

Variant Explanation

This product is available in two NGage material variants:

HB 155 – Whisker Ceramic Brake Pads
This variant uses a ceramic-based friction compound reinforced with whisker fibers. It is classified by NGage as a Whisker Ceramic brake pad. The compound is designed to provide stable braking behavior and consistent friction characteristics under standard road riding conditions.

HBS 155 – Sintered Brake Pads
This variant uses a metallic sintered friction compound. It is classified by NGage as a Sintered brake pad. Sintered pads are manufactured using fused metallic powders and are typically selected where higher thermal stability and consistent braking behavior under sustained load are required.

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

Intended Application

The NGage HB 155 and HBS 155 rear brake pads are direct-replacement components for the rear brake calipers used on the Royal Enfield Super Meteor 650 and Royal Enfield Shotgun 650.

These brake pads are not universal and are not interchangeable with other NGage pad codes such as HB 163, HB 164, or HB 184. They are intended strictly for motorcycles that specify pad code HB 155 or HBS 155 at the rear.

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 follow standard brake service procedures, including:

• Cleaning the brake caliper and pad guide surfaces

• Inspecting the brake disc for wear or scoring

• Seating the pads correctly within the caliper

• Tightening mounting hardware to the correct torque

• Performing a bed-in procedure after installation

Improper installation can result in brake noise, uneven wear, or inconsistent braking response.

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

Summary

The NGage HB 155 and HBS 155 rear brake pads are direct-replacement brake pads designed for Royal Enfield 650cc motorcycles that use this exact rear pad format.

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.
