I have lots of experience on the 1100, less so on the 1300 (~ 1000 miles total)- I really like them both. Would I give up my 1100 to get a 1300? Not at this time. I find the 1100 fairly easy to work on (I was originally timid about working on it)- many here have done far more than I ever ventured to do however (but with time, I have learned quite a bit and this forum is of great help when you do have a repair issue- which isn’t that often). Maintenance is very easy (well, for the 1100 with which I have the most familiarity). Every bike is a compromise of sorts and many things can be changed (suspension, bar risers, seat, etc). I would say an 1100 has a price advantage (at least for now) as the 1300 is a newer bike, and likely a little more money but with more mileage. The 14K 01 you specified, if in decent shape (garaged) and as long as it starts right up and runs well might be a good pick for you (and yes, new hoses and such could be considered down the road a bit)- my timing belt was like new at 33K and hoses looked equally good, so if you get that bike, I think you can start assembling the parts for the job, but it‘s not an urgency to do that work right away. I’d do all the fluids (oil, clutch, coolant, brake, rear drive, and new tires) and then ride it for a while.
For either bike, they don’t do anything ‘great/ amazing’ but do all things quite well and competently. They’re larger tour bikes (1100 more tour than sport/ 1300 more sport that tour). You can’t go wrong with either one. My preference now is the 1100 though (caution...thread drift...I have been researching the NC750X as a local toss around bike, so Who knows, maybe one of those in my future??).
I agree...I would look at comparison articles written in the past (many available online) and decide what’s best for what you want.
