RK XSO Series X-Ring Racing chains - Cut to length
RK racing chains have been the overwhelming choice of FIM World Championship teams for the past two decades! Super tuner & Team Owner Erv Kanemoto has captured 8 world titles as of this writing, and he's chasing number 9. Other prime time factory teams featuring Kevin Schwantz and 5 time and defending 500GP champion Mick Doohan, plus others too numerous to mention, push the RK chain FIM championship total to over 23 since the 1980's alone.
RK chain has also been the driving force behind other World and AMA Superbike/Super Sport teams such as Team Castrol Honda, and countless other teams including Yoshimura Suzuki, Vance & Hines Yamaha and now Vance & Hines Ducati. Fact, RK has won more Roadracing and Drag racing championships than any other competitor in modern times!
