Add a More Comfortable Contact Surface to Your Top Case

Turn the rear of a compatible aluminum motorcycle top case into a more passenger-friendly contact surface.

This two-piece backrest set combines an upper cushion and larger lower cushion to provide padded contact where a passenger naturally leans against the luggage case.

The smooth black finish keeps the installation visually simple while adding cushioning without a bulky external frame or bracket system.

Check Your Top Case Before Ordering

This product is not universally compatible with every 45L or 55L motorcycle case.

It is intended for compatible aluminum top cases with enough rear-panel space for both cushions.

Choose the version that matches your case and compare the cushion measurements with the available mounting area before ordering.

Two-Piece Cushioning Where It Matters

The upper and lower cushions are positioned separately so each piece can sit against a different section of the top case.

The outer surface is made from PU material, while the interior uses foam sponge cushioning to create a softer contact surface than the bare luggage case.

The result is a practical touring accessory intended to improve passenger contact comfort while maintaining a compact profile.

Simple Adhesive Installation

Each cushion mounts directly to the rear surface of the compatible top case using the double-sided adhesive backing.

Before installation:

  1. Confirm cushion position and clearance.
  2. Clean the mounting surface thoroughly.
  3. Allow the surface to dry completely.
  4. Remove the adhesive backing.
  5. Align the cushion carefully.
  6. Press firmly into position.

Avoid exposing the installed cushions to rain for 48 hours after installation so the adhesive can establish proper contact.

No drilling is specified for this product.

Designed for Practical Touring Use

The smooth black exterior is designed to pair naturally with common black and metallic aluminum motorcycle luggage.

The compact two-piece layout adds cushioning without changing the basic function of the top case or requiring a large external support structure.

It is a straightforward upgrade for riders who want additional passenger comfort while keeping the luggage setup clean and functional.

Frequently asked questions

Will this fit every 45L or 55L motorcycle top case?

No. Capacity alone does not determine compatibility. Check the cushion dimensions, available mounting surface, hinge position, and shape of your top case before ordering.

Can I install it on a plastic top case?

No. The specifications state that the product is not suitable for plastic cases.

What is the difference between the 45L and 55L versions?

The two versions have different cushion dimensions and proportions. Select the version that best matches your top case and verify the measurements before purchasing.

How does the backrest attach?

The cushions use double-sided adhesive backing and mount directly to the rear surface of a compatible aluminum top case.

Do I need to drill into my luggage case?

No drilling is specified. Installation is adhesive-based.

Can I ride in the rain immediately after installing it?

The installation instructions state that the cushions should not be exposed to rain for 48 hours after installation.

Is this a structural passenger backrest?

No. It is a padded cushion set mounted to a compatible top case. It should not be positioned as a frame-mounted or structural restraint system.

What should I measure before ordering?

Check the available rear-panel width and height, cushion mounting area, hinge position, hardware clearance, case curvature, and the relevant cushion dimensions for the 45L or 55L version.
