Design: Made of 6061-T6 aluminum alloy, the surface is oxidized, durable and provides longer service life. Knurled screw allows for easy adjustment. Overall length: 1 3.5cm / 5.3". Universal: Fit motorcycle throttle lock, designed for most motorcycles. Easy to install, no tools required. Note: Not designed for tapered grips.
