My opinion , had both GG and KTM , KTM better fit and finish,more available after market everything, 08 and up handle very well and are reliable.KTM downs are :5spd trans, wider at the tank,300's tend to heat easy. GG not as good of fit and finnish but are getting allot better, super good woods handling,6spd trans, power valve adjustability not as easy as KTM , stay cool in extreem conditions, resale values are horrible, very easy to get parts fast through Go-fasters.
