They are calling "New Dink" the Yager in the US. A "Dink" in the US is not a positive thing. It has many connotations including a 'jerk', 'goof', "Desperately In Need of Knowledge" and in Canada it is slang for the male genitalia.
As to the comment about the weight, it is not really the much heavier than the other scoots in the same family. The GV is 359#, the P250 is 348# the Xciting is 407#, the new Downtown300 is 367#, the Yager is 308#
IIRC, all of the 250 scooters by Kymco use essentially the same engine and CVT. The weight of the bike has a large effect on the overall performance of the bike. I guess this is why the X250 is known as a slow bike with same engine/CVT as the P250/P250S and 50# more metal and plastic to move, plus the rider, it makes for a slower bike.
Note: # is a symbol for US pounds
