then how you so sure the quality on par with vespa lol 

on paper, NVX is very impressive i'll give you that , personally i love every bit of it, excluding the 5+ liter fuel tank which for me is too small....
but if you go through the recent yamaha bike in msia , some thing is very wrong especially on the QC side....

as owner of two fz150i, nowadays i dun even dare to recommend other to go and get a fz150 due to this piston ring issue (and unfortunately my newer fz have this issue)...

i use to change every 2000km, but the issue getting worse. and no, motor bike need to change engine oil every 1000km to maintain IS NOT NORMAL AT ALL.

for my bike , it get so bad that weekly checking show that every 500km or less i need to top up ady cuz the EO is not even showing at the dip stick ....
imagine this issue from a brand new motor, this frustrated me a lot....
and what piss me the most is the attitude from yamaha.

i meet up with the wakil yamaha during a survey for all new fz purchase, for some reason the shop i buy that bike selected me.
when feedback my bike issue (my bike even have bad paint quality on the fuel tank, and some part at the fork even start to karat ady), even by terang2 show my proof to the wakil , they still claim that their bike no issue , best seller yada yada....

one of my friend that get the same fz2014, same issue, he even masuk kilang claim warranty, come out kilang , same issue not fix....

one of the co-worker get the new batch fz with gold cover engine, same issue + fork seal pecah at mileage 3000km +
for me , yamaha bike quality is now equivalent to long kang quality ady, and again , this really sadden me to say this cuz i not sure what bike to buy ady at that price.

PCX wins   
Less frequent refuelling. Longer ride distance without any empty fuel tank anxiety 

NVX fuel economy - say if similar to PCX (45km/l), with puny fuel tank (4.6L) then can go up to 200km only...
