All of our covers are 100% CNC machined from 6061 Aluminum billet to give you both great looks and exceptional strength with internally bolted replaceable skid plates. Woodcraft 2-piece engine covers are designed to offer replaceable stainless steel or aluminum skid plates which add wear resistance in the most vulnerable area to keep your bike oil tight in the event of a crash, often allowing for multiple crashes. Give your bike a custom look that will make you stand out in the crowd. This is an engine cover protector. It bolts over the stator cover protecting the lower half.
