Wellcome Qasim bhai...
CG is known to vibrate at higher RPM in even the given models, but rest assured the new EuroII CG is better and has less vibrations, better Exhaust note, and highly responsive, you must give it a try, I can bet my 2cents on New CG its totally worth it, they also addressed and improved CAM, Rokker, and many internal improvements to engine
Hope it helps;
Stay Safe, happy Riding.
