Premium roof box with SlideLock system and whisper-quiet ride
Last reviewed: March 2026

Why this product
The Motion 3 XL delivers 18 cu ft at 44 lbs — lighter than the Black Glossy version and right in the premium sweet spot. Dual-side opening and PowerClick mount make solo loading manageable. The downside? At 165 lb capacity, you get the same weight limit as the smaller L, and you're paying premium pricing for what is essentially mid-range capacity.

The Motion 3 XL offers the sweet spot of the Motion 3 lineup — large enough for a family of four without the garage-clearance issues of the XXL. Same whisper-quiet operation and premium SlideLock system as the L, just with more room inside.
Families of 3-5 who need maximum cargo space without the XXL bulk
Solo travelers or couples who would be better served by the L or M sizes
The XL hits the capacity sweet spot. If the L is not quite enough and the XXL is too much, this is your box.
