Mosko moto Reckless 40 v3 is one of the best mid capacity rack-less systems on the market. Very durable, with outside bottle pockets and convenient "beavertail", it has very little downsides. Actually, maybe just one real downside is that it needs to be moved to refuel your 690/701/700. Not too inconvenient, but sometimes it can be a little irritating, depending on your personality.
It seems like a solution is here, and it's called The Gnoblin.
I won't get in the installation details, as Instructions are posted on the Mosko moto web site. In short, a solid "horseshoe" attachment is bolted to the bag...
...and a matching metal puck is bolted to the bike.
This replaces the rear straps (you can remove them) and bags just clip in place. Lower straps are still used to tie the bags down. Very secure system and makes mounting and dismounting, or just moving the bags, a 5 sec job.
Metal puck can be bolted to almost any bike, to the rear plastics. But all works even better if you have the rear top rack.
Luckily, this works great with many Perun moto rear top racks. Of course, since The Gnoblin is a new product, we couldn't foresee it being used on our racks. But we usually implement 8 mm holes for Rotopax mounts. These holes, usually the forward hole, works perfectly for The Gnoblin and places Reckless 40 or Reckless 80 in an ideal position.
Here is how it all works on Husqvarna 701 Enduro, with Perun moto Luggage rack and Heel guards. Fore-aft placement and angle of the bags is perfect. Lower straps align perfectly with slots on the Heel guards.
Seat is almost completely free and there is some room left on the rear rack.
Although bags are not touching the silencer and rest on the side panels, we strongly suggest using the heat shield.
With The Gnoblin, already great luggage system become even better.
