One of my neighbours had an Africa Twin but he'd had the VT500 before. He gave me the workshop manual for the Vt500, pretty sure I still have it. There's certainly some family similarities between the VT's and the Africa. Maybe less so with the 750's.
Bought mine for £500 in 2012, commuted between London and Brighton, and it gave me way less reliability concern than the much newer, much more expensive triumph I’m on now
I used to have a VT500, bloody loved it but had to get rid when I moved back to London for a bit and my insurance went up x10
