OK What should I say... few thoughts and some feedbacks here I go :
1 - Understand : Zongshen is reaching out all importers/bussinessmen all over the world these days... and your dad is one of there tentative customer just like Xtreme Motor Guys who end up bring one and finally handing it over to Ravi guys.
2 - Superb Idea to gather market Info, but remember PW community depicts a very miniature set of bikers who are educated enough to log on internet as comment on threads here so we are not the real Pakistani Public you will be targeting so keep that in mind.
3 - Remeber the Rule of THUMB : More plastic more failure, the "real pakistanis" dont buy a bigger bike in order to have a shashka but in real they always buy for purpose and they will load it to that extent which is never imagined and all the plastic will tear apart.
4 - Top speed do not matter if you 150cc bike can reach out 110km/h its fine enough but thats not what is going to make a difference, you bike must accelrate better then other 125/150 in the market so that it can reach 110 before other do and you can take off quickly before other do that where tables will turn. 110 speed si already good engouh the question is "TORQUE" will it reach 110 first or the CG or the GS ? if CG then think again before investing.
5- I have been playing with mechnical stuff alot couple of months back I was sitting with a bike magician who just installed a injector and a throtle body from r6 to a 200cc sazgar riskshaw and got 4 HP more from same 200cc and total conversion costed 4k (thats cheap hell cheap and yes sports bike japani injectors too) now he is hired and sits with advising engineers at sazgar rickshaw manufacturing plant. think out of the Box man ab tu mechnics apni bikes abnanay walay hain .. one fine example is Chitta denter who bets that his fine tuned Zongshen/Paiggio 125 cannot be beated by stock CG ... just saw few races in main boulevard few days back and i was more then just impressed.
6 - launch different version,
(i) sporty faty for youngster and speed lovers,
(ii) comuter version whci can tow a truck load with less plastic,
(iii) Awami Bike - a cheap good resale less cc version.
7 - bike with an average age of decade will be enough try to focus on giving constant spare parts and bike will not die in buyers hands ever.
I wich you luck but dont see it happening I dont know Why may be I have become a pessimist after seeing a lot of trolling on PW. but in any case I hope I came handy. bbye
