The bottom line Two helmets, a quick mount and a reflector measured in centimetres. It publishes no load limit and no plastic type.
What the seller commits to paper
52 litres, stated to hold two motorcycle helmets with rain gear and shopping. A quick-mount system with anti-theft locking. A 60 cm integrated reflector. Matt black plastic described as easy to clean.
The reflector, measured
Most listings say “with reflector”. This one says sixty centimetres, which is a specification. A top case blocks the view of a tail light from behind, and what it puts back in its place is worth a number.
The rows this seller leaves empty
The load limit — the figure that governs how much weight can sit high and behind the rear axle. And the plastic type: ABS, PP or a blend all behave differently in cold and in a fall, and “matt black plastic” names the finish instead.

What riders ask about this one
Does a quick-mount system stay put?
It is designed to release deliberately and hold otherwise. Any quick release is also a theft consideration, and the listing pairs it with a lock.
Is a 60 cm reflector useful?
A top case sits where a following driver looks. Sixty centimetres of reflector across it is visibility a box would otherwise take away by hiding the tail light.
Who this one is for
A rider who carries a pillion and wants both helmets to stay with the bike.
