ive never seen complete sets like that...but like 305 said, go to ebay and look, i get "all balls" bearings off there pretty cheap, you may get your wheel bearings in a complete set, but youll prolly have to get the swinger and axle bearings seperate...
i jusr replaced the linkage, both wheel and swinger bearings on a bike of mine for under 60 bucks including shipping...there not that pricy, unless ya go to the dealer..lol..then youll pay a small fortune
