Welcome to the madness from a member that used to live in Sydling St Nicolas
I was a Trout Farmer in the late 70's / early 80's and enjoyed an old Bultaco 250 (DLG 49F) long gone.
I'm in the same dilemma as yourself and am probably going to sell my KTM 990 Adv for the same reasons!
I have purchased a nice Montesa.
I can tell you it is the way forward.
But be ready to kick start again!
(For that reason I didn't go the Bultaco route as left leg kicking is a no no for me ( lol))
Plenty of good bikes around if you want to go back to your youth
OR, Try a Beta Alp 200 with a nice electric leg, these are very underrated bikes
Good luck
