They have 4 valve heads and water cooled 172cc cylinders, maybe where Kymco gets their parts?
They also have the latest greatest roller rockers (for the 4 valve), that's what gives the new Honda PCX150
and Piaggio BV350 their fuel mileage efficiency! Hmm they take paypal too. I wonder how much this stuff
costs?
