My PCX has always given great mpg - it dropped to 129 (actual fuel in/trip) in the colder months but this morning the meter was showing 142mpg! (now on the last 3rd tank). It has always been within a few mpg as the fuel drops from full tank so when I next fill up I expect to get a real figure of 135mpg-ish. Warmer temp and perhaps the fuel moving back to summer fuel(?) has helped.
Other benefit in the UK is being able to filter through traffic, so rather than over an hour through London traffic (or 1hr30+ when traffic is not moving) it now takes little over 30 minutes going home during peak hours as I mix filtering with being safe and law abiding (not taking too many chances and not sitting in cycle boxes or filtering over zig-zags like many bikers do, which only saves a few more minutes anyway).
Great riding in good weather, a bit of a drag in cold/rainy times, but manageable.
