I use a CB500x every day for commuting and site visits.
It’s as dull as ditch water but after 4 years and 36 thousand miles it hasn’t let me down and is as cheap as chips to run.
I guess a NC750 would be just as reliable but even duller.
Honda do reliable, like generators and lawnmowers, just not much interesting stuff.
I think you’re making too much out of chain adjustment. The reality is a chain and sprocket set should be be good for 30 - 40,000 miles, replacing at around 1 to 1½% stretch, in real life that’s no more than about 19mm or ¾" which equates to adjusting the rear axle less than 10mm or ⅜".
Tensioning intervals are dependant on how you ride and quality of chain/sprockets. Ride sensibly, as you would commuting in heavy London traffic and a decent DID chain and JT sprocket set shouldn’t give you any trouble. The 250’s DID/JT chain and sprocket gets properly adjusted from day one, used and abused, regularly lubed especially after being exercised in the rain and I cant remember the last time I had to adjust it, maybe at 8,000 intervals.
The boy is back. Honda NC750 is a dream to commute on. I’ve had them as courtesy bikes and they are really easy to live with. Loads of storage and a low revving engine (Half a Civic engine) it just glides along like like Diesel car.
I’m not very good at adjusting my chain so I just get it done when the bike is serviced every 4,000 miles. When Essential Rubber was still open I asked Mick about a Scott Oiler. He said a can of lube and some discipline was better. Once a week and every time it rains.
It’s 2 minutes work with a paddock stand, even less with a centre stand. You can retrofit a centre stand to an NC750. It already has the brackets in the frame.
Funnily enough I moved out of London so needed to change my SV650 as the long commute on that was starting ttake it out of me so I bought a dullsville.
It is not an exciting bike but you’ll know that, bit it is great for the job I bought it for. Low maintenance, plenty of storage, ok on fuel etc.
The chain thing, you’ll can get the mileage NT mentioned but one thing is the maintenance on it, I got to the point where I was having to clean and grease the chain weekly which became a bit of a chore.
Fwiw mine is a 2007, I had to apply for the Certificate of conformity but I can ride it through London (for the moment at least) without paying Anu of the charges.
