The BMW factory bag does not play well when placed on the seat when fueling, so this is a nice change in that regard. The BMW bag has a contoured base plate and four protruding hooks that snap into the frame rail. The long base and prongs do not allow the bag to rest securely on your seat while fueling.
With the exception of perhaps Touratech (and the BMW factory bag) tank bags are not custom made for each bike model, so tank bags have to work across models and brands. As such, there will always be trade-offs. Gas tank shapes and sizes are all over the chart from model to model and manufacturer to manufacturer, and this impacts how bags will mount.
Illustrative of this point, the RTA straps make contact with the angled edge of pained bodywork up front and there's potential for paint wear if the straps aren't tight and they wiggle around.
RKA offers rubber sleeves that the straps pass through to address this potential issue. I would recommend these for the RT. Or you could fashion your own sleeves. RKA's Richard says it's not a problem if you have the straps tight he's never had an issue on his RT. Did I mention I could be a fusspot?One More Thing
If you're like me, and I know I am, you may be particular enough to be troubled by the Y pads that angle differently from the angle the straps take when anchoring on the RT (illustrated in the photos above). This is a result of bags needing to be somewhat universal in design and work across models and brands. It's just a aesthetic issue, but it bothered me enough that for most photos, you'll notice the wings are tucked under the bag.
There are a couple of options here. Leave it and after a few rides, you may not notice it any more.
You can also tuck the flaps all the way under the bag,
My long suffering wife has offered (after rolling her eyes) to do a angled partial tuck underneath and then sew it together so the pad would end up running along the edges of the tank rail.
I think you could also remove the pads entirely easy enough the same material lines the bottom of the tank bag; and remember, the bag is sitting on the tank bag rails. Modifying the bag may void your warranty
, don't come running to me if it does! I'll probably just remove mine - whatever I end up doing, I'll post back.
SENA Owners Take Note!
Here's your reward for sticking around! RKA has a complete library of information and videos to help you solve your Sena/GPS/Phone pairing issues. Want to use your phone to play (lossless or any kind of) music files AND
get audio directions from your GPS AND
make and receive calls, all through your Sena? I must be joking, right?
You know this because you've tried to do just that or some other combination and were probably less than satisfied.
Here's the decoder ring you've been looking for. RKA has you covered with step by step directions and videos. They cover just about every pairing scenario you can imagine. These folks are serious gear geeks. Sena how to
You have lots to consider when looking for a tank bag. Decide what your needs are and have at it. Several bags now have a hard plastic shell vs conventional materials. The shell may provide better protection for cameras, etc when transporting the bag off the bike. It's also possible the hard shell is less forgiving if you have handlebar interference. Pay attention to measurements, remembering the handlebar interference issue the RT has, especially with radio controls.
The RKA 10 liter bag is the right size when condensed (4 liters) for most of my needs from around town and day rides to most longer trips. Expanding to 10 liter for road trips still keeps it out of the way and doesn't interfere with sight lines, standing on the pegs or when getting on and off all drawbacks of the factory bag. If I'm out for a couple of weeks or more, the larger factory bag will probably be called back into action.
There are several good choices available when it comes to tank bags. The 4 liter compact size of the RKA works well for me. That's not to say it's the only choice. I've tried to illustrate how this bag will work on a Hex/Cam RT and I hope you find this helpful as you make you own tank bag evaluation.
Good Luck! http://www.rka-luggage.com/A01%20Products/prod.html
