    OK much clear in mind. Now just come to final words. My bike goes to 90 to 95 KM/h on 9 RPM. Is this OK?.
    Also what If I go above 9 RPM that is red highlighted and mentioned in manual that going to 10 RPM will be dangerous for your engine.
    What kind of loss I have to bear? and that mean I have to ride maximum in between 90 to 100 KM/h and not try to achieve further.

    90km/h on 9k rpm is very good if your bike still didn't cover more than 5000km and if have covered your bike needs tuning and yes going to redline will kill you engine very soon

    My Bike ran 1900 Km till now But what about those who attempt 110 KM/h? They don't care their machines or have some kind of alteration in engine or parts?

    Red line will definately harm your engine. If your engines life is 100,000 km for e.g, it will be ruined at 40,000 or 50,000 km if you touch red line daily, because red line shows the last limit of your engines revolution.

    If we multiply 6.5 by 12, we get 78 km per hour, which is quite close to 80, these are mechanical meters and some error is possible. This is for GS-150, your CG125 has different gear ratios, therefore it will run at 80 km per hour at a different RPM. Still, 80 km per hour at 8,000 RPM is low for CG125, you should have it checked out.

    Dear Asad this is the actual way to get results or some kind of tukka? As CG has max 10 RPM so if I multiply 8 by 10, I get 80 km per hour, that my bike is giving already!
    In your opinion what should my CG achieve to get admired? (obviously Below red line)

    I don't think CG red line goes up to 10,000RPM, it used to be 9,500RPM. I have not seen service manual or correct specs for CG so I cannot comment about speed per 1,000RPM or maximum speed.
