So I have already posted this somewhere else, but no one has seen it. I am probably buying a GPX, but would like to know before how it is throttled and how much fun it costs me? Are there still things that I should consider when buying this machine? What is the average consumption for normal driving and sports? And last but not least, what is a decent price for a GPX 600 EZ: 07/90 and about 20t km down, is in a good condition? mfg.8ball12355
