verv, not to dampen your desires but I had the worst accident of the lot on a Honda PCX125. My take on it is you're the least respected/seen/looked out for road user. A 30mph crash is a 30mph no matter what you're on. I only had the moped to save fuel going 15 miles each way into central London for work but since then I've vowed to never touch a moped again ever. Not fun getting cut out of your clothes on a mini roundabout because some idiot was texting while crossing it. White boxers in November on the bike? Never again . I did see him coming and knew he was going to t-bone me so twisted the throttle but the bike was too low power to accelerate me out of danger.
Not that you'd go and buy an R1200 GSA but on my GSA I never have to beep, I never have to flash and although I rev while trying to weave in and out of traffic at 5mph people nearly always see me and move first. The road presence is unreal.
Something like the the 400cc Ducati Scrambler which was on SC recently would be lovely and isn't built for speed so won't be a "dangerous" bike. With what they look to be going for on autotrader the price looks like it could be put on a 0% credit card via PayPal and because the initial hit on depreciation has been taken your residuals would hopefully be better.
