GS is more powerful and it is as simple to calculate as 125 < 150 where was the hardest part to understand this.
GS lacks accelration due to its more weight and 18' wheels and almost same torque figure, many bike enthusiast have tested (see @ansee threads or PM him he can provide you details) and certified that CG is more torque and GS has better cruise top speed.
This discussion of CG-vs-GS has already been done a million times so my friend you are not the new guy to confess, so as this empty road drag story is repeated again and again which leads to early thread closing by mods.
Claims of Junnoon hitting 100kmh, GD 110 going above 110kmh are fantascies... I saw GD struggling at 90kMH many times... so what can I expect from more smaller 100cc class bikes...
