2021 Guzzi V7 Special

Most of the Guzzis (and many others) with spoke tube type wheels have "tubeless tires" but with inner tubes in them in order to hold air. Some people (even dealers) mistakenly read "tubeless" on the side of the tire and believe the wheel/tire must be tubeless.

... yes, I have seen this, particularly with the thinner profile of front tires.

Back when I worked at a bike shop you bought either tubeless tires or tubed. Now I hear most are labeled tubeless and you can use tubes if the wheel calls for it. The tires themselves designed for either.

I was told traditionally tubeless tires omit the step of smoothing the inside because it's not necessary whereas tube type tires do not omit this step. More recently, rather than make both types, they just make tubeless and say use a tube if mounted on traditional spoke wheel. Are they polishing the inside of *all* these tires now? If so not very well, at least on the tubeless Dunlop Trailmax that were fitted on my 2016 AT. I probably should unmount the tires on my AT and Tenere' and refit with heavy duty tubes for peace of mind.

Peace of mind could also include an Outex treatment on both V7 spoked rims.

Since I recently contacted one tire manufacturer (since the tire shop had no straight answers), I have one piece of information to add, for whatever it's worth to you. This company said that in order to use TL tires with tube, rims have to be of type MT, and the (new !) tube has to come from the same manufacturer as the tire. So, there are three pieces to match each other.
The CB1100 (spoked wheel or not) has MT rims, as you can easily check on the side your rims.

Peace of mind could also include an Outex treatment on both V7 spoked rims.

... or the so-called "basic conversion" from the Bartfactory, a company in Italy.

It is my understanding the design of the rims used to be different for tube vs tubeless - now.... not so much. This is what drove the change to duel use tires.

Now I'm not really sold on the same manufacture of the tube must match the tire (as a parts manager that would be a nightmare to keep in stock! So it would probably be a special order in most cases), so I'd be interested in the rational for that (other than monetary).

When visiting a Guzzi dealer, I saw one bike with tubeless spoked wheels, not a conversion, OEM design.
It looked like this:

202x Honda Africa Twin AS models have similar rims, in keeping pace with the BMW ADV models.

Honda's version of the rim has seen rim failure at the spoke endpoint.

Anyway, if every used on a MG V7, due to its tame power and rider usage, I doubt it would become a problem.

Those tubeless spoke wheels look just like what BMW has been offering for over 30 years now. I haven't looked closely at the ones HD offers on the Pan Am, do they use the same design?
The ones Yamaha uses on their Tenere' 1200 incorporate a raised flange allowing the spokes to be attached closer to the center of the wheel rather out at the very outer edge.

The KTM 1090 I had used a more conventional spoke wheel with some kind of sealing band to make them tubeless but recommend it be replaced every so many years.
