Lifting the rear of a CB500F, CBR500R and CB500X is uniquely challenging. The swing-arms have no threaded holes for spools and are at an angle. Without spools the bike can be difficult to lift with a stand. Once lifted, it can be unstable. The angle on the swing-arms makes it worse. It can cause the bike to slip off the stand and fall. T-Rex spool adapters are made to meet this challenge. They are designed to securely attach to the swing-arms and allow safe lifting of the rear wheel using a paddock stand.
