Having had my VX-1 for 2 years, the fact that I've never seen one out in the wild doesn't surprise me. However, my last two trips to Italy (June 2016, Sept 2017) was delighted I spotted two. My first trip I saw a pretty worn VX-1 in Milan, parked among the other scooters. This last trip (while touring Italy on a BMW C650GT) we had stopped for fuel and a coffee at an Esso station in Salerno. While seated outside enjoying the espresso, I hard a 'whine' vs a scooter engine, looked up and saw another VX-1 go up the hill.
Nice to see some are still out there soldering on. (And to celebrate took mine out for a bit today)
