feels more like it. i have tested a friend's CG125 euro2, which topped at almost same speed.
But above 80Km/h, CG125 start feeling unstable and gripless. You can do 100 on straight road, but when it comes to ups and downs, and turns, CG125 scared me at high speed. Thats where GS comes in. This is the machine actually made to be used at 100Km/h. At 100, it goes like breeze and makes you want even more 10-20km/h speed 
That being said, my bike have done 500Km only, so may be top speed will increase with a bit more mileage on meter.
