Luggage
Top box or panniers
These two put the same luggage in very different places, and the machine notices.
By Jean-Benoit Buisson
Where the weight goes
A top box puts it high and behind the rear axle. That affects steering more than the same weight anywhere else on the machine, and it is why a load limit matters so much there — and why almost nothing publishes one.
Panniers put it low and at the sides. Better for handling, worse for filtering, and you have to know how wide you now are before the first gap.
Load limit, per case. One pannier set in this catalogue publishes 5 kg each and it is the only luggage here with a weight figure at all. Everything else publishes a volume, which says what fits and not what the mounting was built to hold.
External and internal dimensions. The outside decides clearance; the inside decides what goes in. Wall thickness and lid structure mean they differ by more than you would guess, and one aluminium case here publishes both.
The mounting standard. “Universal” is a word. A named system, or a base with a stated number of fixing holes, is a specification — and a named system that your machine is not already fitted for is a second purchase the listing does not price.
What a top box buys that panniers do not
A place for your helmet to live. That is the whole argument for a commuter, and it is a good one.
What to check before ordering either
Whether the brackets are included. One case in this catalogue states plainly that they are not. Most say nothing.
