I kept ZXMCO for five years, it was not this model it was the imported lot from China with alloy rims and Disc brakes, One thing i can tell for certain is that I sold that bike after 56k on the ODO, its average was at 60 when i sold it, Oil change was at 4500KM, no smoke. And the original parts that were installed were of excellent quality and far better than even what Atlas Honda offered. Only problem i faced was that original part were not available and I needed to move to 4 wheels. The friend who owns it now is still using it on sealed engine and 72K.
Now the ZXMCO available in Pakistan i cannot comment, But if it is original ZXMCO chinese than use it and it will serve you well.
Best of Luck for the purchase and Enjoy
