SyedMoazzam bro, as you may have noticed no one has showed much interest in the subject yet. So I am hoping the plan is on a halt for now. Nevertheless, I am still interested in doing it and wish some GD guys in particular and other riders in general would come forward and help make a successful trip in the coming days.
Maybe our friends here are waiting for this layer of intense heat to subside and then think of going out, rightfully so. Meanwhile, if you have any guys in Lahore or elsewhere who may be interested in a trip to Murree, do call them in and let's plan it.
Good luck with your purchase, brother. You might not enjoy the tempting fuel economy of Suzuki Sprinter in Suzuki GD 110, you will surely find it more comfortable and a quality product (not undermining the quality of Sprinter, I hardly remember anyone EVER complaining about any issues in Sprinter besides its well-known hard seat issue - no engine complaints ever, remarkable!)
And if you are to consider any other machine alongside Suzuki GD 110, then let that be Ravi Piaggio; please keep the other names you mentioned out of your list. These two are really good contenders for your next bike in my point of view.
I hate to do it, but let me highlight an issue I am facing my GD now a days: it struggles to "breath" as I push the throttle. It seems to have lost its high-end power. Its pick is good at lower speeds - it goes from 0 to 60 km/h in a reasonable amount of time, but accelerates sluggishly beyond that mark. I talked to a Suzuki mechanic and he said its air filter might be chocked up, but I cleaned its air filter only a few weeks ago. He further said I should bring it to him on next oil change and get it tuned. So I am waiting for the next tune up and see if the problem is fixed. The last resort would be to open up the fuel supply (enrich the mixture) to its already fuel-thirsty engine.
