You are looking at a twisted grooved Spiked bungee cord frankenstein bolt set. This 2 piece set is manufactured from 300 series stainless steel and polished to a chrome, mirror finish. 300 series stainless steel WILL NOT tarnish or oxidize and will always keep its chrome like shine. A perfect way to customize the Hayabusa.
We also manufacture mirror block-off spikes, and our fairing bolt dress up kits that compliment this set.
