Got a used SW Motech Engage tank bag.
REALLY nice!!!!
Does NOT touch tank.
Easy off to fill up with gas. Easier ON when done.
Huge Optional map pocket.
Optional GPS / PDA mount...not sure this works too well on the GS as it might block speedo or tach.
Has compartments that keep things apart and one can be moved.
Stiff sides- doesn't flop around.
Bright red liner- can easily see what's inside- unlike the darkness of a black liner/bag.
I will likely also get the "GS" version for trips. Much larger.
Could be better- Cell phone pocket is too small and I'd rather have it fit my I-Pod.
- Front pocket would be nice for the rain coat, but the GSA handlebar crossbar moves the bag back enough where you can't use it.
