These spindle sliders mount directly through the rear spindle axle of the Zero FX '19- and DSR '19- providing both crash protection to the rear components, protecting the swingarm and components, like the brakes and drivetrain in the event of a crash or drop but also functioning as paddock stand bobbins, allowing the bike to be lifted up on a Rear Paddock Stand for cleaning and maintenance. 

The best of both worlds!
