Awesome find for us older bike folk! Except that R&G seems to be based in Europe...was hoping for a US based shop.I found Sliders that fit the 95-97 ZX6R's finally, R&G Racing sells them (google for website). They also sell spools.
The sliders are great, they come with a replacement watertank too, so everythign fits correctly.
For other stuff liek farings, mirrors, for the older bikes this website is sooooo soo cheap. (Click on metric bike)
