    Derby cover only
Black Fin Derby Cover is rated 4.8 out of 5 by 11.
Rated 3 out of 5 by from Very beautifull but very delicate I have mounted it with new correct gasket (not the OEM O-Ring obviusly) and the cover broke immediatly during the strenght of the screws. I have respected indication of the IFU regarding the load of 10-12Nm and I have closed the screws at 11 Nm. I have noticed the thickness of the bolt seat appears very thin respect the OEM cover, I have bought a new one and the tickness is the same, I haven't mounted it yet because I'm scared of broking it too! Better to leave more aluminum in the bolt seat than to make it so delicate

Rated 5 out of 5 by from Just what was needed. I love my 2016 Low Rider S but it is sooooo black that I'm not sure it is even recognizable as a Harley more than 20 yards away when looking for the derby cover that just faded into the blackness. The horizontal lines on this cover make it clearly stand out as a Harley and the lines work well with the cooling fins on the motor. Just what this particular bike needed. They ought to install them standard but that ain't the Harley way.

Rated 5 out of 5 by from Awesome Look I bought the matching Black Fin timer cover to go with this Derby cover. They both look awesome on my Slim S, and really bring out the engine finish on my 110!
