BigKing Motorcycle Tail Box,Motorcycle Rear Seat Bag Waterproof Back Saddle Helmet Tail Luggage Bags Box, Black

I bought it to pop a 2 meter heavy motorcycle chain and lock in. I don't like leaving a topbox on the bike as it gives temptation to thieves, so I fit this to my rear seat and pop the lock and chain in it so I don't have it over my shoulder when riding (quite heavy lol.)It unclips easily from the straps that remain on the seat, light to carry with you when you leave your bike. The holding straps can be easy to put on and off if you have any pillion passenger. Comes with a rain cover, not used that yet though

Fits well to my pillion seat, in front of a top box. Whether it would be secure enough without a box behind it, l’m not sure, but for my purposes, I’ve no complaints. I needed extra capacity without too much bulk, to go with a top box and tank bag. It fits the bill.

Very small I got for a helmet like it shows you can't put one in just using for bits that's all not worth the money
