Rizoma rearsets are the cats teets! They have individual components that can be replaced if you crash...as opposed to having to replace the whole rearset. They are Italian so you should be able to get them over on your side of the pond.
However, if i were you, I'd at least contact
www.pjsparts.com and see what they can do. They get pretty dam good deals on Rizoma stuff! Maybe they can waive the shipping fee and have it sent to you directly while still in Europe prior to coming to the USA.
Paige and PJ are top notch people!
