The Necessity of a Twin Cam Derby Cover
As a motorcycle enthusiast, I have come to appreciate the importance of having a well-functioning engine. And one crucial component that helps maintain the performance and longevity of a motorcycle’s engine is the derby cover. Specifically, for twin cam engines, using a twin cam derby cover is necessary for several reasons.
Firstly, the derby cover serves as protection for the inner workings of the engine. It shields the cam gears and other internal parts from debris, dust, and other contaminants that can cause damage or decrease efficiency. This is especially important for twin cam engines because they have more moving parts that need to be protected.
Moreover, the derby cover also plays a role in maintaining proper oil circulation within the engine. As it covers the primary chaincase, it helps keep oil from splashing out while riding and prevents dirt or debris from entering. This ensures that clean oil is consistently circulating through the engine, keeping it lubricated and running smoothly.
Another reason why a twin cam derby cover is necessary is its contribution to aesthetics. A well-designed derby cover can add a touch of personality to your motorcycle while also enhancing its overall appearance. With various designs and finishes available in the market, you can easily customize your bike
My Buying Guide on ‘Twin Cam Derby Cover’
As a motorcycle enthusiast, I understand the importance of finding the right parts and accessories for your bike. One crucial component for any Harley-Davidson Twin Cam engine is the derby cover. This cover not only protects the clutch assembly, but it also adds a touch of style to your bike. In this buying guide, I will share my personal experience and provide you with important factors to consider when purchasing a Twin Cam derby cover.
Material
The first thing to consider when buying a derby cover is the material it is made of. The most common materials used are aluminum, chrome, and stainless steel. Each material has its own advantages and disadvantages.
- Aluminum: This is a lightweight option that offers durability and corrosion resistance. However, it may not be as visually appealing as other materials.
- Chrome: Chrome derby covers are known for their shiny finish that adds a sleek look to your bike. However, they require regular cleaning and maintenance to prevent rusting.
- Stainless Steel: Stainless steel covers offer both durability and a polished look. They are also resistant to rust and corrosion, making them a popular choice among riders.
Design
The design of the derby cover is another important factor to consider. You can choose from various designs such as plain, engraved, or custom-made covers. Plain covers offer a simple and clean look while engraved covers add a unique touch to your bike. Custom-made covers allow you to personalize your derby cover with graphics or text of your choice.
Fitment
Twin Cam engines come in different sizes (88ci, 96ci, 103ci) so it is crucial to ensure that the derby cover you choose fits your specific engine size. Improper fitment can lead to issues with clutch engagement and potential damage to your engine.
Budget
Twin Cam derby covers come in different price ranges depending on the material, design, and brand. It is important to set a budget before starting your search so that you can narrow down your options and avoid overspending.
Brand Reputation
Last but not least, consider the brand reputation when purchasing a Twin Cam derby cover. Look for brands that have been in the market for some time and have positive reviews from customers regarding their products’ quality and durability.
In Conclusion
Purchasing a Twin Cam derby cover may seem like an overwhelming task at first, but with these factors in mind, you can make an informed decision that suits your budget and preference. Remember to always double-check fitment before making a purchase and opt for reputable brands to ensure quality and longevity of your new derby cover.
