Ok so u need a cheaper and economical bike to gift it to someone.. But u need re sale too.
Hmm... Well Honda cd70 is the answer for you, else you can check with local mechanics and market people about the quality and resale of other local brands..
All 70ccs sell quick bcoz theres alot of market 4 them, but make sure u buy the right one.
DYL 70 wasnt much successfull at first but they removed its faults in newer models and now it works f9... check DYL first as its the most old and experienced company in local bikes...
Metro is f9 too bt nothing gr8,
pak hero is crappy,
sohrab is a ****.. my frnd has it.
Superpower is f9 too...
But ill sugest u 2 go 4 CD70, a used one is btter than a new local bike.
