I read your post about giving the ST to your brother with a bit of sadness, I could tell there was a bit of melancholy there, watching/hearing it drive away.
I was actually pleased to be able to pass it on and say - "Here you are". I'd been working on it for my future use for the fork refurb and brake refurb, but then I had to take things off that I needed and prepare it and double check everything for him and I quite enjoyed doing that - getting it ready for its new owner. I thought that the excitement of a completely new machine, looking pristine, and the prospect of a new style of riding would be at the fore front of my mind.
So the feeling of sadness came as quite a surprise.
Looking forward to Friday now.....

Brother has been out on hi new-to-him ST1300 today, and commented on how much better it was in the twisties (than his ST1100).
In the meantime, the garage shelves are being ransacked for all of the things that are stowed away 'in case they come in handy, and never have for the last twenty years. I found and ditched a load of pushbike stuff today: including two Campagnolo end of handlebar derailleur gear changers. I lusted after these when I was about 14 and saved up for ages to get them.
I had them on my road bike(s) for many years - until I was about 40, I guess, oh and an old Brooke's leather saddle that I had broken in, was beautiful to ride with until it started breaking me in. But I couldn't bear to part with it at the time. I've never seen it since, it was tucked away with some other bike junk.
I don't much care for the 'not being one of us' discussion between the three whelers and two wheelers. I'm sure I will get on it and think that I am pleased that we are able to extend our time on motorcycles - and I was very torn between lighter bikes, a bike and sidecar combination and eventually the Spyder. I am very certain that the Spyder will be VERY different to ride. The lack of a front brake lever was obvious as soon as I mounted it. The handling will be way different - but I have made such a conversion before - going from motorcycle and sidecar to a solo ST1100, with an 18 year gap in beween. Countersteering was a brand new concept that I tried to work out. If I push on the left bar, it turns left, not right. Yet if I'm going slowly and want to turn right, I still push on the left bar and it turns right. How does it know. I was contemplating this while practicing on a deserted dual carriageway one sunday morning. I was approaching the roundabout and had to stop. I didn't know what to do !!! I set off again and decided not to think about it - just do it. I am sure that I will have similar experiences on the Spyder. But I still sit on it. I'm still in the elements with my all weather gear and crash helmet. To me I will be riding a motorcycle.
Apparently, in the UK you can ride one of these with a car licence or a bike licence.
