How to Choose
When selecting a motorcycle trunk, start by measuring the available space on your bike’s rear frame and checking the bolt pattern. Hard shells provide superior protection for fragile gear, while soft trunks are lighter and easier to pack around irregular items. Look for an IP rating of at least 65 if you ride in wet climates; higher ratings (IP68) guarantee water resistance even when the trunk is fully loaded.
Consider the mounting system: bolt‑on kits offer the most secure attachment but may require drilling, whereas strap‑on or quick‑release systems are tool‑free and ideal for riders who change bikes often. Finally, evaluate load capacity and additional features such as internal dividers, lock mechanisms and modular accessories to ensure the trunk meets your specific riding needs.
