The Kawasaki Triples Club is a real good bunch, they can be found
hereI would also highly recommend the Worldwide Z900 Owners Group - they have members all over the place, especially in the US. They can be found
here. I reckon these guys would be one of the best 'Global' groups around. Fergo has Z900 history !! (just a bit

), so this group, and their global links, might be very handy......
Of course, don't forget about our mates over at the ZX12R forums, they could be particularly helpful if needed. They can be found
here. I think these guys are pretty much US-based, but may be able to help with racetrack experience ?? There are a lot of ZX12 drag-racers on this forum as well....
That should do for starters, hopefully there will be a few more added from other members soon.
