When you ride a motorcycle you are carrying all of the weight of the motorcycle through your hips, lover back, shoulders and neck.
Although the bike may seem to weigh very when you are riding it, when you get off, you'll damned well know about it, it's not the actual kerb weight, it's the kerb weight being moved through the certrefugal force as you tip the bike in and out of corners.
As you get older you need a lighter bike, more upright, with a lower centre of gravity if you suffer from dehydrated discs in your spine, or worse still prolapsed discs
I moved from an ST1300 Pan European onto a Transalp in 2012 for this reason, though I always felt the bike upright and comfortable it carried what weight it had high, and the V-Twin caused a lot of vibration above 5000 revs, which was most of the time an motorways and country roads above 60mph.
The NC700 and 750 cure the issues of intertia and weight for older / physically challenged riders. The long stroke parrell twin is low reving and smooth, the centre of gravity is low, and by cantering the cyclinger heads forward you will suffer less from the certrefugal forces when changing the lean angle left to right, both Pistons are moving in the same direction.
Michael Cysk developed a 4 piston engine with the cylinder heads configured like a boxter bit vertical, no certrefugal force at all the test riders said, I will wait for Honda to copy the Douglas twin from the 1930's, with the cyclinger heads opposed but in line with the wheels, bet that would be smooth.
As a motorcycle the NC is rather unique, and it took me a while test riding it to understand it.
The engine is more characteristic of a small car, smooth, laid back, not in a rush, but in a motorcycle frame that translates into quite astonishing performance, at low revs.
It doesn't make much noise, and short shifted gets down the road with remarkable speed, it is just so laid back you don't realise.
It corners well, in fact it wants to tip in and corner quickly, it's just so balanced and quiet, and at such low revs, you don't imagine it will.
What's it like?
It is astonishing, unique and ahead of it's time.
Many bikers will poo poo it, not a proper bike they will chorus, but those that ride it will most likely fall in love with it.
A modern classic in my opinion, and the prototype for the the future of motorcycle engineering
