I have purchased items from all the above sites with no problems at all.
Another helpful site is -
http://www.ninja650shop.com/ - although i haven't purchased any thing from these guys so can't give any advice.
I am trying to find infill panels for the plastics around the rear seat so that i can get rid of the heavy handles that never get used. If anyone has any ideas please let me know.
Cheers.
