This is interesting, went to see if any info on KPT400 on the American Lifan site, and noticed these:

Motobi was an Italian brand, apparently part of the Benelli group that QJmotor purchased. So we have QJ, Benelli, Motobi, Lifan, all have lines of bikes. Lifan to my knowledge is a separate corporation.

That mpg figure might be due to a test of a pre-production vehicle?!
