Panda, I can see you went back and clarified your decision considerations and so forth. My response looks like I have trouble with reading comprehension (although Iím not sure today is any different than any other day).
I think Keith and Paddlefoot gave great advice.
I wouldnít be put off so much by the low mileage. I just had a 2015 899 Panigale evaporate under my eyes...it only had 476 miles on it. Probably a dentist or an accountant bought it and decided it was too much bike. Anyways, find the shop it was serviced at, ask questions, etc, etc.
I will say based on your description of intentions, I think the SS will hit the sweet spot.
Iím probably lending to your confirmation bias but sometimes that isnít a bad thing.
So, lemme get this straight.
I twist this little tube, it gets loud, I go forward really fast and it makes me smile...is that how it all works?
