if your gunna buy this thing dont
you can put the same amount of coin into a pit pro and get the silver lifan 125 its a heaps better motor
have a look around this site do your research it will proove my point
do a search for the black lifan motor
The MSO 140s (witch i have) has the gray (GOOD) moter in it and is well bilt i highly recomend it and the service from MSO is unmatched from all other sellers i have delt with if you need any info on there bikes contact them and thay will help ypu out.
will u stop making threads! the pro is much better then the x6r thus why it is so much more expensive!
look... the only difference between the two is the clutch set up! one is start in anygear... one is not... and they may also have different gearing patterns! ohh and the head on the black lifan is cast iron, the silver head is alloy
