I'm about ready to pull the trigger on a Reflex. Any problems with 6'2" and 240lbs? Seems I read somewhere (maybe here) that the bars hit the knees on taller guys in tight cornering will this be a concern for me? It will be used mainly for commuting but will also see some road work. Think 600 miles/day a few times per month. Can this scooter maintain runs of 60mph or so w/o a problem given my size? I'm also considering an older Helix (Honda fan - sue me). Is there more long distance back support on this model compared to the Reflex? Thanks for any input.
