How to choose your motorcycle saddle bag?

Set the volume (in litres) to suit your needs; an expandable model adapts to short trips as well as weekends. Waterproofing is key: opt for a roll-top design or a rain cover to protect the contents. The fastening straps must be stable and not slip under acceleration; check compatibility with your saddle (single or dual seat). A non-slip base and solid anchor points keep the bag from moving. Also think about the handles and the shoulder strap for carrying on foot.

Frequently asked questions

How do you attach a motorcycle saddle bag?

Most attach with straps passed under or around the saddle, sometimes with quick-release buckles. Tighten the straps well and make sure the bag touches neither the wheel nor the exhaust, and that it does not slip.

Is a saddle bag really waterproof?

Welded roll-top models offer good waterproofing; others are only water-repellent and need the supplied rain cover. Check the closure type so you can ride with peace of mind in the rain.

What saddle bag volume should you choose?

For everyday use, 10 to 20 litres is enough; for a weekend, aim for 25 to 35 litres, ideally expandable. Choose according to your trips and the volume to carry, without unbalancing the motorcycle.
