ADVGear, a growing line of storage accessories for BMW adventure motorcycles, has developed their latest product, the Pillion Box. This one of a kind secured box snaps into place of the pillion seat on the liquid cooled GS and GSA bikes.

You can remove and replace the box as you would the seat: using the ignition key in the bike’s seat lock. The pillion box features a weather-protected combination lock that you can program with three digits.

The latch can be used to secure the lid of the box with or without engaging the lock, making the box as handy as a tank bag, but very secure simply by scrambling the combination dial.

Powder coated inside and out, the box is roughly 10” Wide x 9” Long x 3.25” Deep with a capacity of 6 liters. The flat top is designed to have dry bags, a tent, or other gear loaded on top as needed. For more information about ADVGear and their Pillion box, go to ADVGear.net
