I agree Ebay is NOT a good source for kymco, but if you shop different o.e.m. dealers for price you will find as much as 20% diff. on the part. Also by researching you can use DIO or GY6 parts, and there are loads of performance parts for these. 60 on an Italian scoot? is that kph, or mph? my zx runs 65-68 mph, verified. But I try not to beat it all the time. It's my primary ride
60 mph, 50 cc, 2 stroke. NRG mc3 from 2003, old model, stock, 5.5 hp.
http://bikes.88000.org/wallpapers/99/Piaggio_NRG_MC3_DD_Super_Scooter.jpgIn the past I owned NRG extreme 50 LC from 1999 that I had tweaked (new carb, ZX Leo Vince exhaust, 72 cc kit), it did 120 km/h. Of course, subtract at least 10 %, but still respectable - it could measure up with lots of heavier 125-200 cc scooters.
Also the way 50 cc Italian scooters corner is unmatched by anything produced by Kymco - on the contrary, Kymco's People 250 S has way better handling, cornering and braking than Piaggio Beverly 200 or 250!
So, this talk about this scooter or that scooter brand is pretty much a question of personal preference, geographic location and what you really need. For people in USA customer support for European scooters is bad, for people in Europe, spare parts and support for Italian scooters is much better than for Kymco or other products from Far East. Usually you will not get best sports performance from Kymco scooters in economy class. Kymco makes great economy scooters (less than 200 cc) but when they try to make 400, 500 or 700 cc scooters, they become just as expensive and not quite as good as their Japanese or European counterparts.
Personally, I think that Kymco is not on the good track. Chinese competition has started gaining reputation and it is closing in. Take a look at Keeway that has several great models (Outlook 125/150) for example, good dealership and it is 25 % cheaper than Kymco.
I still think that both for Kymco and a lot of European and Japanese premium brands the profit margins are quite high and they are earning on hype, and I am telling that as owner of two Kymcos.
