Paddock stand bobbins by R&G Racing for Kawasaki Ninja ZX-10R / ZX-6R.
The cotton reel is mounted to a special, black-anodised aluminum bracket (included with the kit).
The product will give protection to the swingarm area in most crashes.
Also the bike can be lifted on the cotton reels, using a paddock stand with hooks (suggest R&G code SH0001).
