I have been searching for some extra fuel capacity for my 990 A and my Jesse luggage system. Options available: 1- CJ aluminum tank didn't work due to Jesse luggage mount limitation 2- Rade under the seat tank not possible due to my ABS 3- Rotopax I didn't have where to mount beside the rear but didn't want due to the extra weight on the sub frame 4- ADV tank same limitations of the CJ's aluminum tank due to Jesse luggage mount 5- Safari tank to expensive to import in to Brasil Some months ago I meet a friend that developed a solution for his Vstron and he already has done about 75K miles with this system. So he made one similar system to my Jesse Luggage. One stainless steel tank of 4.7 L attached to the bottom of each pannier They have a latch type of fixture where I can place a lock to prevent unwanted friends.. It is very easy to remove Internal view of the attachment mechanism The locking mechanism to prevent fuel thief The plastic hose to fill the thank to prevent fuel spill The thanks removed from the bike For sure this is not perfect and has some limitations but for my needs I think they will do fine.
