Re: Tank bag choice: SW Motech "Engage" or "Daypack"
I have had an Engage tankbag for my K1200GT. I bought it in 2008 or 2009. Honestly, it is too small for my long distance trips, so I ordered the much larger City and Trail bags, intending to return one of them after I see how they fit on my bike. They are still new in the box. One of these days I'll try them out.
Another problem I had with my K1200GT was that a full-lock left turn on the handlebars can push the horn button into the Engage bag. I bought a Wonderlich horn guard that solves the problem. I do not know if it is an issue for an R1100GS or if a horn guard is available for that bike.
There are two types of mounts for SW-Motech / Bags Connection tank bags. Be sure you get the EVO mounts. (The ION mounts are older, and are being phased out.) You will need one tank ring for each motorcycle you own, plus a top ring for each tankbag.
Furthermore, the mounts come in two types: Electrical or non-electrical. The electrical mounts automatically pass electricity from the bike to the tank bag whenever it is mounted. You can use it for charging cellphones, for example.
You can get many accessories for the SW-Motech system: tankbag GPS mounts, camera mounts, map pockets, lighted map pockets, and more. They already come with a quality rain cover, hidden in a tiny pocket. I have a map pocket that attaches to the Engage (or any other bag in the system). I use it whenever I attach the tankbag. It holds pen/pencil, receipts, and a log book for recording mileage. Be careful, the vinyl window can be scratched.
My Engage tank bag has been on many cross-country trips for tens of thousands of miles, in all weather conditions - desert heat, mountain cold, bright sun, rain, snow, hail, you-name-it. Frankly, the bag looks almost new.
