To elaborate on what I had said before:
You had an Almax series III chain, so 16mm.
You can check on the Sold Secure website:
https://www.soldsecure.com/approved-pro ... _types=165
but only 22mm and 25mm chains are rated sold secure motorcycle diamond.
The 13mm, 16mm and 19mm ones are rated motorcycle gold.
But the 22mm and 25mm cannot be carried around and won't fit most wheels.
So I thinks the best security remains a tracker (maybe monimoto) + diamond ulock, which you can carry around, possibly combined with a gold chain to be left fixed outside your home or office.
This still leaves you exposed to the risk that they may come with a van, cut the gold rated chain there and then, load it onto the van, and worry about the motorcycle diamond rated ulocks later. Possible? yes. Likely? I doubt it - unless you have an MV F4 Serie Oro

You can look at the video review at the bottom of: https://www.bennetts.co.uk/bikesocial/r ... y-security
With a mains-powered grinder, it took more than 5 minutes and 6 discs to open one of these u-locks. On a battery-powered one, it would take longer, but most thieves do not carry multiple batteries and multiple discs.
Imagine having 2 u-locks of that kind - a thief would need about 12 discs and who know how many batteries!!!
On Trackers: Bennets has a good page here: https://www.bennetts.co.uk/bikesocial/r ... le-tracker
I would personally not put a tracker connected to the battery on a scooter, unless I can connect the scooter to a battery tender when I'm not using it for more than a week. if you want to do that, the Datatool draws less battery than the Biketrac. Actually, a good alternative could be to use a solar trickle charger; Oxford covers have a pocket meant for the Oxford solar chargers, and they work quite well.
With any tracker, you must be careful to place it somewhere where it's hidden enough but not so hidden that metal etc will jam the signal. One thing you could do is to consider a fake decoy tracker, this could be an airtag or something similar, placed somewhere easy to find, plus a real one, better hidden. But this won't fool the thieves who steal a bike and leave it somewhere for 24 hours just to check if it has a tracker or not.
On DCT bikes and shoving: I think shoving another scooter is easier from a lighter scooter with a low centre of gravity than from a Honda DCT bike. I'd also presume most gentlemen engaged in this noble art are more familiar rising scooters than motorbikes, and maybe not all know what a DCT even is, but that''s just a guess.
Any more questions, just ask.
