Welcome to the forum.
So you want a cruiser ala Harley Davidson?
Well, It depends on a lot of variables... Such as: your experience with motorcycles, your budget limit, and most importantly your intended purpose i.e on what type of roads you intend to ride your cruiser.
I'm from Lahore, and over here, I often see Suzuki Savage 650's here on sundays. It's not your typical Big Inch V-Twin Cruiser though. It's a 'tiny' (Its a 650cc which is indeed tiny in The World of Cruisers) simple SOHC single cylinder air-cooled twin valved Thumper (if I remember right) hence local mechanics won't have much trouble rectifing a minor or even a moderate problem. What's more? Older ones are fed by a Carburretor! Whereas Its latest incarnation, Suzuki S40 has an EFI (I think).
A guy on an S40 passed by me once and it sounded like a vintage VW Beetle! So, it sounds good for a thumper.
Alternatively, you can look-up Honda Shadow 600 or 650 or maybe even the latest 750 if your budget permits. But keep in mind that Shadows are powered by a 'proper' engine i.e its a V-Twin which means twice the work. And secondly, they're water cooled which adds even more complexity hence you better find a mechanic whose 'specialisiation' is big complex engines!
The reason I recommended them is because these are by far the MOST POPULAR cruisers in Lahore and you'll often see them over OLX.
