Installation and compatibility

The bag can be mounted on the classic Atlas tubular frame for aluminum cases in seconds without additional adapters. It can also be adapted to most tubular frames with an 18 mm diameter, including OEM frames from BMW. The BMW R 12 G/S is expressly listed as a compatible model.

For extreme use, the manufacturer recommends additional horizontal straps attached to the hooks on the backing plate and the side loops. The padlock for the roll-top closure is not included.
