BMW Tankbag Gallery

Here are some pics of various bags I've done. I don't have a complete listing as I have to rely on the folks who buy my bags to take pics after they receive it as the bags don't look like much sitting on my work table.

R1200GS Bag R1200GS bag without the standard map pocket
R1200GSA an alternative to a traditional tankbag. These are panniers and a RallyBook.
RT bagThe 2005 version of my bag has pockets on each side and nearest the rider. The side pockets are narrow to keep down the 're-adjust the windshield at full lock'. It may still happen as I haven't ridden with the new bag. Each pocket has water-resistant zippers that should be waterproof as long as the sliders are not horizontal. Each pocket also has an optional exterior flat pocket covered by a flap with reflective material. The 2005 version bag on an R1100RT with bra. The bag features exterior pockets on each side and nearest the rider. The side pockets are narrow to keep down the 're-adjust the windshield at full lock'. Each pocket has water-resistant zippers that should be waterproof as long as the sliders are not horizontal. Each pocket also has an optional exterior flat pocket covered by a flap with reflective material.
 Here's the bag flipped forward for fueling.
Other optional features are:
Zippered compartment on the bottom to accommodate a tethered rain cover. This may be redundant as I think the bag is fairly waterproof, but some folks need this. The cover has Velcro on the top to attach the map pocket. The second zippered compartment is to hold a back-pack type strap for easy, no hands carrying.
The bag attaches to base using two side-release Fastex style buckles and two strips of Velcro
 
Here's the interior of the bag. It's been electrified with a Powerlet tankbag kit and features two interior zippered pockets in the upper lid.
It's 10"x12.5" so it'll hold a regular sheet of paper. It has a water resistant zipper on the bottom on the right long side. It's attached with velcro and a swivel clip to a D-ring on the front of the bag. You can increase the water shedding ability by using some AquaSeal or some equivalent product on the nylon ribbon on the outer edges.  
Here's the base alone. It has one zippered pocket and one pocket with associated D-Ring for side stand plates.
