Small motorcycle backpacks: compact size and low weight are different choices
Choose a small backpack by its usable compartment layout and loaded fit. Compare the manufacturer's empty weights separately: a compact motorcycle pack can still contain substantial harness, lining and reinforcement. The smallest stated volume is not automatically the easiest bag to live with.

A phone and wallet need a different carrying solution from a water reservoir, spare layer and lunch. Put your smallest regular load on a table first. Then add the one or two items that make the bag worthwhile on your normal rides.
If a laptop is part of that load, its dimensions may determine the minimum pack size before litres become relevant. A compact bag that cannot accept the device with the intended sleeve is not a useful commuter option, even when the remaining cargo would fit easily.
Read how the litres are divided
The Kriega Trail9 has 9L total capacity split into a 4L waterproof roll-top compartment and a separate 5L zipped hydration compartment. It is a useful compact candidate for that particular split, but its name does not mean 9L of uninterrupted waterproof cargo space.
The Kriega R16 provides a different arrangement: a single 16L waterproof main compartment. A buyer carrying folded clothing or a lunch container may prefer one larger space even if the nominal size looks less minimal. Consider the dimensions of the biggest object, not only the combined volume of smaller ones.

Kriega lists the Trail9 at 1,030g and the R16 at 1,346g. Those figures help compare what the bags add before packing. They are not rider load limits, and they do not establish which harness will feel better on a particular person.
A lower empty weight may come with fewer dividers, less structure or a different weather system. Decide which of those features you would immediately replace with accessories. A lightweight shell plus several added organizers can become a more complicated purchase than the original specification suggests.
Consider a simple dry compartment
Oxford's Aqua V12 is another compact approach, with a 12L waterproof roll-top design, welded construction and an external pocket described as water-resistant. It is worth considering when your shortlist brief is a modest amount of dry storage rather than a dedicated hydration layout.
Check the number and placement of openings against your routine. If everything lives in one compartment, a small pouch may help manage loose items. That can be useful simplicity, provided you are happy to open the main closure at stops and do not need multiple external access points.
Try the smallest and ordinary loads
A bag should manage a short outing as well as the day you fill it. Check whether its compression system can reduce unused space and whether the upper edge remains clear of your helmet in your riding position. Evaluate fit over your actual jacket rather than an everyday shirt alone.
Resist adding external attachments merely to preserve a smaller model name. If essentials routinely spill outside the bag, the next size may be the more compact real-world setup. The best small backpack is the smallest complete solution that closes properly, organizes the load and fits you.
