Woodcraft RSV4 LHS Stator Cover Protector Assembly Black: Aprilia
The patented replaceable stainless steel (or Aluminum) skid plate adds wear resistance in the most vulnerable area and can keep your cover both functional and looking good through multiple crashes. The plate is internally bolted so that you don't have to worry about trying to remove bolts with the heads ground off.
Note: This is an engine cover protector. It bolts over the stator cover protecting the lower half that is vulnerable in a crash.
