Let me give some clarity. The bike was equipd with 3.50-18 Trail tyre that has projection & circumference equal to 4.00-18 plain tyre so the gear ratio was not stock thats why bike was able to hit that speed relatively on less RPM. The ROad smoothenss was one of the best as per my driving/riding experince.(KKH From Gilgit to Hunza). Regarding the stock GS 150 that cud easily hit 110 KM/Hr this figure is as per my own & other PBC members experience with GS 150 without Euro 2 ASV device. I am not sure how the new GS 150 engine behaves.
Another thing which i need to mention is if u r comparing GS 150 with CG 125 classic then in most of the cases u will not be able to beat the CG 125 but GS 150 has its own riding pleasure which is far away from CG 125.
