Actually Not ALL Asian or Import Scooters are that way . Sorry to hijack the thread but I felt I had to respond .
I have a group of friends who actually travelled to the Orient and toured the various scooter plants to possibly be dealers and as a first step did the research . Some better brands such as Kymco , Qlink and now Sym are fully robotic factories and did away with the manual welder assy line workers that used to work in the laundry marts in the Communist countries where you were told what to do aka "Today you are all welders " and Bam , you are . The Korean bikes are of much better quality . Even the scooters in India were actually pretty good .As you stated ,underneath all the swoopy plastic ,the frames are usually the same as well as the standard GY6 engine - a clone of either the Yamaha or Honda bikes. Electronics are usually the same so parts are dime a dozen , shocks ,gauges ,rectifiers ,batteries ,wheels ,belts ,gaskets , cylinders ,valves , solenoids ,pistons , rings - All the same - so I disagree with you there in terms of parts replacement. You will have to do your own footwork to find a source of parts either online or a local dealer and install yourself but All you have to do is figure out what engine you have GY6 QYM139 50cc 150cc 2-stroke (yes there are still a few around) 4-stroke . Note: I would replace ALL hardware (with american nuts bolts screws) They haven't gotten down to that level of producing good hardware - Their foundry skills are severely lacking - ie casting shift on their cases or cylinders - again, not all - Lifan or Hysong(spelling?) is actually OK - Their full sized CVT motorcycle was impressive for a moped and scooter guy like myself .
The Asian companies that went after the US market ,invested the funds to be EPA ISO compliant. They stopped building 2-storke products first of all . Dumped old product - yeah they dumped we bought .
These few companies also invested in training the factory workers from literally the cleaning ,laundry and sewing factories/industries to mechanical assy aka motorcycles scooters and yes ,cars. The ISO compliant factories started actually following the guidelines and kept track of serialized frame numbers and following Quality Control guidelines . Before (remember all those 2-stroke bikes on Ebay during X-Mas 5-6 years ago? ) there were NO serial numbers stamped on frames and they could not be identified in the event of a safety recall hence could not be registered - the old stock was dumped on Ebay -( we bought them ) and the new practices began however the reputation of the Chinese bikes were toast and still is by the uneducated (and I mean that not in a mean way- do your homework on the product ) . They are just now becoming recognized by the educated and growing number of people who did the research to find out which brands are garbage and which are reputable and roadworthy . The garbage manufacturers are finally getting their act together and complying and applying to ISO 2001 standards or die . I have a MadAss clone, did the homework found out the frame is indeed made alongside the original and bought one haven't had any problems except the crappy mirrors .
Point, I'm trying to make is "Do the research" so you can speak, as an educated consumer not a teenage kid who heard from a friend whose bike broke trying to jump off a rooftop and broke his leg and still wants to look tough.
Ask around to someone who actually has a scooter you are looking at for a first hand opinion. You're a mechanic so you can overlook stuff that is not important .
BTW - To offset the cost the bikes will go super cheap on the mirrors , tires batteries bulbs etc . Note :Batteries are not really crap as first thought we figured out that they sat in bikes as tested from the factory then sat in a warehouse then sat in crates on a very slow boat from china then sat in another warehouse etc - guess what? not running a bike sulfates the battery - any battery . Oh crap sorry for the ramble . I'm done .............
