Even though I love my NT1100 I would be interested as likewise I dislike cleaning and oiling the chain
Yes, so keep that to a minimum, or less.
Well oiled chains, especially if too oily, leads to collecting dirt and dust, leads to cleaning. Sometimes less is better; that's the approach I took with my last chain drive bike, the Honda CB1300.
Got it at around 28,000km, previous owner said that it was due for a new chain and sprockets. Pfft, I think it was and around 50 or 60,000km that I changed them. In the meantime, it had a clean and oil before and after every long ride, that was about once a year or at around 5000km intervals. The chain and sprockets were changed again at around 110,000km (when I sold it).
This strectched the chain and sprocket maintenance intervals out quite a bit, but the chain and sprocket longevity was probably no less / worse than normally expected.
I had a mate that was (probably still is) obessed with chain maintenance. On a couple of interstate trips he would oil his chain on his Suzuki Bandit 1250 at the end of every second (~500km ) day. Other mates and I would spend our end of day time more wisely, sitting in a bar.
Another mate installed a Scott oiler, all good until it had some sort of hissy fit and made an awful effing mess. I think it got tossed into the bushes on the side of the New England Highway somewhere north of Armidale.
I think it's simply because a shaft drive is very low maintenance, but on the other hand a chain drive does not soak up as much of the engine power. On my long trips with my XJR1300 chain drive bike, I found the regular chain cleaning and oiling to be rather tedious.
Imagine how fast a chain drive ST1300 would be.
