      Rated 5 out of 5 by from Sleek Design Love this Derby cover. Simple, but sleek design. Perfect for my ride. As a bonus, the price was very reasonable. I shopped around, and for the money, this was a great buy.

      Rated 5 out of 5 by from Great quality This finishes out my CVO air flow trim, and this part is top quality just remember to ask for a gasket I would recommend this part to anyone and is very easy to install if you have a center stand.

      Q & A

      Why no Transmission side cover?

      I see most collections have transmission side cover, timer cover and Derby cover. Why the omission of a matching transmission side cover!??!?
      Asked by: LD13
      Hey LD13, Actually, we don't offer trans trim in the majority of our Engine Trim Collections. Only our Live to Ride, Flames and #1 Skull collections offer this type of cover.

      Flat gasket or o-ring style gasket for this cover?

      Asked by: Ultra2014
      Hi Ultra2014, A flat gasket would be required for this Airflow Derby Cover. Thank you for your question.
