Yes, there are multiple names for this bike. I wish they printed the average of all the bikes so they were easier to compare. I look at the midrange, and also the highest mpg averages.
That little XV looks good to me too. Probably about the narrowest bike out there (except some thumpers), very low seating, the handlebars are tall but that is easily and cheaply corrected, and the bike is very light. And the undersquare engine, along with a single carb (I think) for the two cylinders making carb adjustments easy. Skinny but largish diameter wheels minimizes rolling resistance. Air-cooled means faster engine warm-up.
I wonder with some radical pullback bars, if the seating position could end up like some recumbent bicycles?
