Actually I’ve owned four boxers and a parallel twin GS in the last decade.
The RT was a BMW recall because it was (quite literally) a death trap. The 1200GS had at least three recalls that I can remember (fork shims etc). The 1250GS had those foot pegs that kept falling off. The 850 had failed switchgear and leaky auxiliary lights (a problem that the RT and the 1200GS also had).
The only one that has “worked perfectly” is the UGS. I still have it and like it a lot.
As for the 1300, apart from the GSA having looks that only a mother could love, you don’t have to read far on here to get to tales of woe about failed switch gear and panniers that either fall off or don’t work - and that’s after you’ve waited 18 months for them to be delivered. Even replacement engines on factory-fresh bikes.
I’m no GS hater but I am bored with being a factory Beta-tester so I’ve switched brands.
Turns out you can still buy bikes that don’t have to go back to the dealer umpteen times a year and that the paint still sticks to after more than a few days in the rain…
