I've got that issue and just had a look back over it. GG got a good rap. Marzocchi CC forks heaps better than previous Sachs forks. Ohlins 888 shock always good. Motor was a bit faster and snappier than KTM, comes with a map switch, racier and not quite as easy to ride as Kato. GG looks cool, build quality better than previous.
Grouches were that the steering lock is restricted by the frame spars (nothing you can do about it) and seat was rock hard (personal preference?). Also air filter access involved seat off and swing battery out of way.
Summed up Kato still more sorted as a package (8.7 kg lighter too!)Gas Gas much closer overall and more exciting power.
