Few advices from my side
After getting custody of your bike. Better to go for maximum exposure.
1. Make your own website (not just a Facebook page). Including discussion page and suggestion, pics and videos.
2. At YouTube channels, Call haris of "horsepower pakistan" or "datbikerdude" to review your bike and make video (they are having good number of subscribers on youtube)
3. You should have any office or small showroom where people can visit and have a look to bikes, in person.
4. Search all the facebook pages and similar social websites and those websites having serious readers...... Show them what you have.( You can make an article with your website address and paste it). Pakwheels, propakistani.pk, and driver.pk are few of them
5. You can also collaborate with similar bike shops all over pakistan. For orders and delivery to customers in that city. Eg. Sigma motors in lahore (dealing mainly with sports bikes)
6. I personally dont have in depth knowledge about engines but among efi and carburetor better to focus on that bikes whatever the majority of mechanics can understand.
7. Keep your margin to minimum initially (remember whoever will purchase your bike becomes the ambassador of your product.) if he will be happy. He will make you happy by gathering more customers.
8. Put your bike ads regularly at olx with website and showroom address. To get maximum boost
Good luck buddy
