This purchase is for a pair of spool adapters for the models above. Lifting the rear of FZ-07 quite 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 safely lifting of the rear wheel using a paddock stand. The aluminum brackets are lined with UHMW-PE (ultra high molecular weight polyethylene), a tough plastic with good strength and wear resistance. This plastic keeps the aluminum brackets from scratching the swing-arms. The spools are made of UHMW-PE. If you want anodized spools, please specify during checkout.
