188mpg Yamaha retrobike

[DonBarletta]

About this 125cc Yamaha. They officially call it the 2011 Y125 MOEGI. And yes, Yamaha states that it is officially 188 mpg in the US cycle. Yamaha has
also released a short manufacturer's promotional video about it at YouTube entitled "2011 Yamaha Y125 MOEGI Concept at The 42nd Tokyo Motor Show 2011 第42回東京モーターショー " It is interesting to me that Yamaha has gone to the trouble to not only make this finished pre-production prototype, but also their promotional video as well - since they have stated they will never manufacture this motorcycle. Even if they did, it would probably not be sold in the USA, as we all know that almost none of the high-mpg production vehicles currently manufactured, are sold in the US anyway. And why is that? You'll find more about the MOEGI at Gizmag [dot] com, entitled "Yamaha shows retro lightwieght 125cc motorcycle that gets 220 mpg".

I'm pleased that people reckon mountain bike tires would do the job .If they're the right size that would be great .There are some excellent bits of gear out there, rims and tires .

I wonder what speed that 188mpg was at ? 25mph ? It's not very aero especially with a body on it !

188mpg, before hypermiling and streamlining it ...

A quick play with our calculator Aerodynamic & rolling resistance, power & MPG calculator - EcoModder.com giving the bike and rider a total weight of 140 kg / 290 # roughly ,CD of .85, 6 squ foot frontal area ... 35mph gives 192 mpg US .

Probably reasonable for an urban commuter .

Weren't the old Mopeds mpg rated for about 35 mph? Maybe it's same-same for the new bike.
