Scooters and small motorcycles

I was amazed at the low prices for scooters and small motorcycles on sale at Soriana. 150 - 250 cc ranging in price from 20,000 to 24,000 pesos, or ballpark $1100 - $1300 US or $1400 - $1700 Canadian. They are likely all manufactured in Mexico. Quality may be a question mark, but their low price explains the proliferation of these vehicles on Zihua's roads, which increasingly look like Saigon/Ho Chi Minh City.
Back home I ride a 2007 "super scooter" 650 cc Suzuki Burgman, but a new one there runs $13,000 or more, Canadian.....and a small 50-150 cc Honda or Yamaha scooter would likely be three or four times as expensive as one of these Mexican models. We're apparently getting ripped off.
