What is a derby cover

A derby cover on a Harley-Davidson bike is a metal plate, which is usually made using sheet steel. A derby cover is used for covering the clutch of your Harley-Davidson motorcycle. The main utility of a derby cover is to protect the workings of the clutch from possibly harmful dust, dirt, and other possible contaminants. 

The origin of the derby cover can be quite difficult to identify. The term “derby cover” isn’t even listed in the Oxford English Dictionary. It might have been named after the derby hat, which is also an ornament of expression. The conjecture is very likely to be a possibility, since the first Harley-Davidson models were manufactured around the same time that derby hats were in fashion in the United States. These hats were used by eccentrically lavish individuals who used to attend the Kentucky Derby horse race during that time.

Since derby covers come in many different and unique designs, it can be quite difficult to choose the one that is perfect for you. If you are not particularly intrigued by the idea of following the pack, a good idea would be to design your own derby cover and get it custom engraved. There are many derby cover engravers on the Internet who have extensive experience when it comes to dealing with a Harley-Davidson derby cover.

Derby cover designs and models

Typically, derby covers come offered in three-hole or five-hole models, which will depend on the specifications of the motorcycle that it is connected to. This five-hole cover will offer more durability and protection. Since there is a wide assortment of derby covers that you can choose from, there will also be a wide range of prices. The lower-end derby covers are available for around $7 whereas the higher-end derby covers can go as high as $400, especially if they’re gold-plated. Derby covers serve a number of functions, such as holding license plates.

Custom-designed derby plates are pretty common on Harley-Davidson bikes, as they promote the individuality and free spirit associated with these bikes. The design engraved on the plate will be typically selected by the motorcycle’s owner with a special symbolic expression in mind. For example, if the Harley-Davidson rider is a die-hard Harley-Davidson aficionado, there’s a wide selection of chrome derby plates that comes engraved with assorted Harley-Davidson insignias. The classic derby cover is made up of simple smooth finished chrome and is free of any engravings.

How to change the Harley-Davidson derby cover

Since derby covers come situated in an easily accessible part of the motorcycle, they are rather simple to change. Motorcycle mechanics should always remove the derby cover when they are checking the internal mechanics of the transmission. For example, if you want to check if the throw-out bearings have to be changed, it’ll be important to remove the derby cover of your bike first. If, accidentally, your motorcycle’s derby cover is damaged or not reinstalled, the workings of the transmission can be seriously compromised.

One common mistake that most Harley-Davidson bikers make is that they replace the O-ring under the warped derby cover without changing the cover. Usually, a warped cover can be almost as bad as a damaged one, or in some cases, not having a cover at all.
