KXA00433 is a lockable, removable hard-luggage case for the Himalayan 450 / New Himalayan, Himalayan 440, Scram 440 and Bear 650 when the correct model-specific rear rack and mounting plate are already fitted.

Verified Specifications

Confirmed Fitment

The top box is not bolted directly to the motorcycle. Correct fitment depends on the motorcycle having the exact rack and mount plate specified for that model.

Check Before Ordering

1. Confirm the motorcycle model: Himalayan 450, Himalayan 440, Scram 440 or Bear 650.
2. Confirm you want the silver 40L top box KXA00433, not the black version or mounting plate.
3. Check whether the correct rear rack and mount plate are already installed.
4. For Himalayan 450 and Scram 440, confirm the KXA00434 mounting plate or the current specified equivalent is present.
5. For Bear 650, confirm rear rack 1990536 and mount plate 1990537 are present.
6. Check your helmet dimensions if helmet storage is the main requirement; peaks, cameras and intercom units can change fit.

Not Compatible / Do Not Assume

• Himalayan 411 and Scram 411
• Guerrilla 450, Hunter 350, Classic, Bullet, Meteor, Interceptor or Continental GT models without exact manufacturer-approved rack and mount evidence
• Universal or third-party mounting plates
• Direct installation onto the motorcycle without the required top box mounting plate
• Loads exceeding 5 kg

Purpose

Adds secure, lockable hard luggage for touring, commuting and weekend travel. The rigid shell protects packed items better than exposed soft luggage, while the quick-release design lets the box be removed from the motorcycle without tools.

Box Contents

• 1 x Silver Adventure Top Box
• 1 x Backrest pad pair
• 1 x Locking lever
• 1 x Locking lever cup
• 1 x Inner cover
• 1 x Degreasing wipe

Motorcycle rear rack, top box mounting plate and waterproof inner bag are not included.

Installation

Professional fitting is recommended. Install the correct model-specific rear rack and mount plate first. Position the box so its mounting bobbins align with the plate openings, slide it into the locked position and set the internal locking lever exactly as instructed. Confirm the lever is fully closed before every ride. Backrest pads must be positioned carefully on a clean, dry surface; their adhesive bonds immediately and reaches full bond strength after approximately 72 hours at room temperature.

Care & Safety

• Never exceed 5 kg total payload.
• Distribute contents evenly and prevent loose items moving inside.
• Check the lid, lock, mounting lever, plate, rack and fasteners before every ride.
• Do not ride if the mounting lever is not fully closed.
• The box is water-resistant, not fully waterproof; use KXA00294 for waterproof internal protection.
• Clean with mild soap and water; avoid abrasives, solvents and direct high-pressure spray at seals.
• Added rear weight changes handling and braking; adjust speed and riding style.
