The Ninja250 is a great pocket canyon racer for the money but I actually see it as a poor bike to start with for hypermiling. The only reason they are so popular on ecomodders is the cheap price and availability. And it is one of the few bikes sold in the US with less than 600cc's so there aren't many choices. It is a super sport bike with peaky cams. If someone made fuel mileage cams for it and you installed the dual channel, programmable, wide band fuel injection kit from the group buy at Ninjette.org it would be much better. 70mpg stock versus 85 for the CBR250R is already making my point. The Ninja is far from the best choice from a hypermiling competition stand point. The best hypermiling motorcycle that can be ridden on real hiways as a daily driver is the CBR125R. A +1 on the front sprocket is all that is needed to have a 90mpg commuter that can top out at 75mph. Still a real bike for a solo rider with gorgeous, functional bodywork. Sadly, not sold in the US. I am going to import one eventually. But, air cooled will beat water cooled. Not for longevity but it will be more fuel efficient. Water pumps waste power. Any of the air cooled 125cc cheapos from India get way over 120mpg right out of the box but can't reach beyond 60mph. Until you change gearing and add a full streamliner fairing. Used bikes in India would be in the $6-800 range. Not anything to go touring on, like either of the 250"s are, but a great start for a competition vehicle.
