Great report as always, Win!
Hope you continue to enjoy the Aprilia. I had an SR50F with the oil-injected DiTech engine which I derestricted and did vario tuning on (this was before I had my bike license). It was a very stable, comfortable, and peppy scoot for a 50, and I still smile when I think back to going down the road in heavy rain on it, a pair of Joe Rocket saddlebags loaded on because I was on a multiday trip, and a Triumph Tiger 2-up passes me. We meet up about 4 miles later at the ferry landing waiting for the boat to Tsawwassen, and the look on his face when he realized it was only a 50, was priceless. It would run a good 90 km/h no problem one up, and 80+ 2-up.
