All very interesting.....
R1300GSA here (manual) approaching 3,000 miles.
Background, 7th GS/A since 2000, yes before Longway Round changed the World forever! had most variants of the model. Probably well over 500,000 miles completed on all of them combined (Iron butt rider too)
The best bit of the 1300 GSA? is all day comfort and engine power. Yes it's not the best looking, but who remembers the reaction of the R1150GS and it's looks when launched.
Like all of the boxer engines I've owned, getting better with more miles.
How would I sum it up? easy, has a bit of every model I have owned, as said since 2000.
Each to their own, above is just my humble opinion.
TD
PS...lucky to own one as just retired (using the kids inheritance) LOL
