It takes more than 15 minutes to get a feel for a bike IMO, I will agree the GS does have what some people refer to as "character".
The Yamaha has grown on me, and with a couple of (relatively) cheap mods is massively improved - but to a degree you are correct, but nobody has had any major problems with one.
As for GS recalls, I understand there have been at least three:-
1. Problem with oil pumps (before anyone even took delivery!)
2. Problem with "forks" not being tightened properly
3. Problem with Traction Control modes
Plus it seems a fair few clutch issues, some problems with switchgear (indicators and hazards having a mind of their own) and several oil leaks.
I am sure it is a fantastic bike to ride, and probably is better than my Yamaha in some ways, but my bike goes well, handles well and seems pretty much indestructible with many bikes now past 50k, one bloke up at 85k and many more in the 20k - 30k bracket with no more than a few rusty spokes and a couple of blown fork seals reported in hundreds of thousands of miles of use.
Sorry for the hijack, please get back to reporting on the new GS, which I do not doubt for one minute is an awesome machine to ride
