Recently I received Fatty tool roll from Mosko moto. Like all Mosko moto stuff, very cleaver design and excellent built quality. It is not small, but it can accept lots of tools. Unique feature of this tool roll is that it is waterproof.
This makes it ideal to be mounted on Perun moto 1X90 Side carrier.
90 degrees bottom flanges on the Side carrier prevent tool roll from sliding down, no matter how heavy it is.
And placement of the slots is perfect match for this tool roll.
Here is front view of Tool tube / Fatty tool roll combo. Profile is narrow enough.
If Reckless 80 is carried on 1090, 1190 or 1290, there is a gap under the bag base. Exactly this space is utilized by Side carriers.
