Adjusting the bags to achieve the perfect fit might look daunting at first. Setting upper straps is not intuitive and it takes some time to figure out how they work. However, once done, there's no need to adjust them while using on a same bike. It's a solid, stable system which will not loosen up over time.
There are several ways in which upper straps can be attached. From my experience, using a single strap, which loops through the Luggage rack and connects both bags is a good option. Not the fastest way to install or remove the bags, but it still doesn't take a lot of time.
From the photos above, it's obvious that the fuel cap is easily accessible.
To prevent bags from being damaged while riding off-road, I adjust the width so that bags are not touchingthe luggage rack.
Set-up like this, the bags rest entirely on the side plastics. This makes them more stable and there's no noticeable bounce even on bumpiest trails. Yes, the plastics will get scratched even though the Blizzards are padded. Use of a self adhesive protection film is advised if scratches bother you.
Additionally, bottom of the bags, even with optional bottle holsters installed, never comes close to the silencer. Using the heat shield still might be a good idea, just as an added precaution.
Specific shape of the Enduristan Blizzard bags has several benefits. They will not interfere with rider's movements on the bike. And the top of the bags is almost flat and flush with the seat. This is great if you plan to add larger tail bags.
Adding Perun motoExtension platedoesn't influence fitment of the Blizzard bags. Upper straps still pass through the slots on Luggage rack.
However, with the Extension plate installed, it's possible to use Enduristan straps with metal hooks. This makes installation and removal of the bags simpler and faster. Note that the hooks will damage powder coating of the Extension plate over time.
This setup is great for riders who need to carry larger tail bags as the Extension plate has big surface area.
