These fit all 07-2020 ZX6/636 engines. Right side pieces have never been down, clutch cover has been down once, obviously. The skid pad took all of the damage, as you can see in the one side profile picture, damage to the actual case is nothing but cosmetic from rock/debris abrasion. I thought about using black magic marker on it, but I did not want to look like I was hiding anything, but I'm sure that would cover it up enough that to make it not noticeable from more than 2 feet away. Stator and the starter idler gear cover reuse the OEM bolts and gaskets. The right hand side case guard uses the (3) longer bolts, pictured, and are included as well. $260 shipped to the lower 48.
