Motorcycle top boxes: sizes, brackets and fitment

Compare storage capacity and mounting systems, then check a motorcycle-specific rack or bracket before buying. A 32L or 39L box can be useful storage, but capacity alone never proves fitment.

What to check

  • What capacity fits my bike?
  • Which bracket is required?
  • Will a full-face helmet fit?
  • What is the safe load limit?

Check the motorcycle first

Open your motorcycle model page to check mounting, size and fitment notes before choosing a product.

Top boxes with checked catalog records

Product cards are shown only when MotoIndex has a checked, renderable product image. Every verified record remains available below instead of pretending a missing photo is verified.

Top-box brands and product families

Fully checked models get detailed product pages. Other families stay listed here until we have enough reliable model, specification and mounting information.

LTO announced that the ₱100 registration fee for custom-made motorcycle top boxes and saddle bags was removed. This does not replace safe mounting, load-limit and road-safety checks.

Motorcycle top-box questions

What size top box should I get for a motorcycle?

Capacity depends on what you carry, but liters alone do not determine motorcycle fitment. Check the box mounting interface, bike-specific rack or bracket, rack load rating, subframe limits and tail/seat clearance before buying.

Does a motorcycle top box need a bracket?

Usually yes. Some boxes include a universal plate, but the motorcycle still needs a compatible rear carrier or bike-specific rack. MotoIndex only calls a model fit verified when a specific manufacturer rack or bracket record is stored.

Can any top box fit any motorcycle?

No. Capacity and plate type are not enough to prove fitment. The exact motorcycle, model year, rear carrier, plate interface, fasteners, load limit and clearance all matter.

Does LTO charge a registration fee for motorcycle top boxes?

LTO announced that the ₱100 registration fee for custom-made motorcycle top boxes and saddle bags was removed. Riders still need to follow applicable mounting and road-safety requirements.
