These Swingarm Protectors, for Suzuki GSX-R1000 '17- / GSX-R1000R '17- models, fit into the rear spindle and expand to a snug fit, looking great and protecting the swingarm. They are held in place by means of their expanding design, meaning installation is very simple. They help protect core, expensive components found around the swingarm area, such as the brake calliper, disc, sprocket and the swingarm itself!
