Suitable for the Kawasaki Z800 ('13-).Are they cotton reels or spindle sliders? Well they are both really!!The Cotton Reel is mounted to a special, Stainless steel block, replacing the existing chain adjuster brackets. The product gives protection to the swingarm, rear disc and chain areas. Also the bike can be lifted on the Cotton Reels, using a paddock stand with hooks (suggest R&G code SH0001).
