Arlen Ness Rotor Adapter (manufacturer part no. 300-081)
Designed for riders who customise their front ends, this Arlen Ness Spider adapter allows for the installation of a 320 mm floating disc with spoke mounting on Arlen Ness cartridge hubs. Forged from aluminium and then CNC machined, it follows the lines of the Ness Cartridge hubs while reducing overall weight.
When installed with a 320 mm spoke-mounted disc, the adapter forms a complete and lightweight disc/hub assembly, compatible with standard 5-bolt HD wheels and a 3.25" rim. Important: designed solely for Arlen Ness wheels equipped with cartridge hubs and intended for use on original rims.
Ideal for touring/custom bikes, it particularly suits recent heavy touring models such as the Road Glide and Street Glide 1923. Do not alter geometry or mounting specifications without verification: adhere to manufacturer recommendations for installation and tightening.
