Having just entered the wild world of scooting last year I'm none too experienced so I hope you'll all excuse my cluelessness in most regards

About a year ago I was only commuting about 3 miles on roads with speed limits anywhere between 35-45, so a 50cc scooter was a perfect fit; I'd never once driven on the highway

I really, really like the look and feel of Genuine scooters, and the Blur especially has captured my attention. The only concern is that, according to the review on justgottascoot.com, the Blur 220i only reaches an actual top speed of about 68mph and suffers from an extremely optimistic speedo. Have any Blur 220i owners here experienced anything different? Both of the mechanics at the Boston scooter shop I visited recently ride the new Blur and they love it, but I wonder just how highway-capable it may be. And, even if it does reach the rated 75+mph, is it healthy to push it to its maximum for about a half hour each day? Is there another scooter that you might recommend for this kind of usage?
Any input would be extremely appreciated!
