Hi Bruce,
There are still a few around in Spain (very few ever made it out). However, they tend to be fairly messed around with and uncared for, unfortunately.
But I get the impression that this is changing. The Spanish classic bike magazine, Motos de Ayer, recently carried a well illustrated article on the Vento - you can see it here

This is late model one, 1982 to be precise.
I can't remember now who the manufacturer of the wheels is, altho' I think it may be FPS - I ought to know, but I don't and I can't go check 'cos the bke is about 1,00 miles away from me at the moment. I don't think it's Speedline, altho' they look similar. Anyways, they weigh an absolute ton, not like the lightweight Speedlines that came on some of the twins. In fact, I've just bought an set of earlier and much lighter wheels which I may get round to refurbishing and fitting one day ...
The bike's all up and running now, altho' I do need to change the clutch which is pretty knackered.
Fun, eh?
Ciao
Craig
