Tank bag size and position are issues for me.
While I was at the 2-Day Adventure Course at the BMW Performance Center in Greer, SC, the lead instructor took my 2022 G310GS for test ride to check out the mods I had made, mostly the Rally Raid suspension and the KKE-Racing VMX cross-spoked wheels. He was no stranger to the 310GS, having had an early one himself. He said the bike was much better than the OEM version, but that he really didn't like how far forward the foot pegs were compared to the 1250GS.
When I was riding off road at the Georgia Mountain Rally a week ago, I noticed that while standing, my legs/crotch were constantly against my SW-Motech tank bag (see post #5 above); the foot peg position was forcing me that far forward. Before my next ride, I attended a session on Short Rider Tips with Kandi Spangler; one of the things she mentioned was she didn't use a tank bag because it interfered when she stood up and that was on a 1250GS. On my next ride, I put my tank bag in my tail bag to see if no tank bag made a difference; it made it much easier to maintain a standing position. On my ride home, with my tail bag now full, I reinstalled my tank bag and adjusted it as far forward as the handlebars allowed. Being a Pro version SW-Motech's tank bag, this involves loosening four bolts on the underside of the tank bag, sliding the underside base backward, and re-tightening the bolts. With the bag positioned forward, I found the leg/crotch interference while standing to be tolerable.
Because of this, I won't be getting Mosko Nomax tank bag. On the 310GS, it's large size and how far it extends rearward means too much leg/crotch interference while standing for my purposes.
The pics below show, via the vertical blue line, the foot peg position relative to the seat. They also show how little tank bag space the 310GS has compared to the 1250GS. These are studio pictures by BMW with the vertical blue lines added at the center of the foot peg. I carefully maintained the aspect ratio of the originals so I believe the scales are approximately the same in each. The relative lengths of each, 86.9" for the 1250GS and 81.7" for the 310GS (81.7"), supports this.
Anyway, food for thought.
