The axle protectors are essential to protect your swingarm in case of a fall or a slide. This unit absorbs the impact that would otherwise be transferred to the aluminium swing arm of your motorcycle. The two endpoints are connected with a solid steel axle machined on CNC automatic machines. All hardware used is 100% stainless steel and is lifelong rust-free. The endpoints are made in a very dense polymer (not ABS/nylon). The unit is not to be used as a paddock spool mount.
