A 70s or 80s 2 stroke trail bike might suit you well. TS, RT1, DT etc. Buy and Import from the states and register it or buy one that is already over here.
Cool for days, great on smaller roads, can be taken on the lanes, relatively easy to look after at home, more than powerful enough, low stand over, super easy to ride, light.
Drums are the only questionable area but they aren’t that bad when set up and you adjust your riding accordingly. Not as comfortable if you are doing big days in the saddle in comparison to a newer bike but more than happy to sit at 60-70 if you get a bigger capacity one. The smaller sub 250cc will happily do 50-60 constant.
