After several rides, I am more than happy with how this combo fits on 690.
Installation is a breeze and bags can be removed in no time. They fit very well, fuel opening is unobstructed. Although it is advisable, heat shield is not a necessity, as bags are sitting on the plastics entirely, not touching the silencer.
This video shows how we mounted OS-Base on the 2019+ KTM 690 Enduro R.
And here is how we fitted Kriega US-20 and US-30 Drypack on the rear rack, using Kriega OS Rack loopsand strap loops. When Kriega mounting hardware is properly used, Drypack can be mounted and removed in seconds. Following video illustrates how I mount US-20/US-30 Drypack on our rear rack.
Here is the bike with OS-18 Adventure pack on each side and US-20 Drypack on the rear rack.
