Proper care will ensure the longevity and appearance of your MJDDJA motorcycle model.

- Storage: Store the model in a cool, dry place away from direct sunlight to prevent discoloration or material degradation. Keep it away from extreme temperatures.
- Handling: Always handle the model by its sturdy base or main frame. Avoid picking it up by delicate parts like mirrors, handlebars, or exhaust pipes.
