I had the head cover chrome plated, which cost around 40,000 yen. I'll explain the process, including various important precautions.

Is it okay to chrome plate a motorcycle head cover?

In my opinion, it’s fine to chrome plate the head cover on a CBX1000. The reason is that the CBX1000’s design allows the engine to be easily visible, unlike many other motorcycles where the head cover is more parallel to the ground and less noticeable. The CBX1000 appears to be designed with the concept of showcasing the engine. While chrome plating may slightly reduce heat dissipation, I still chose to have it done. The prominent visibility of the head cover means that it has a design setup that naturally enhances the air cooling effect.

Although chrome plating does reduce heat dissipation to some extent, it doesn’t eliminate it entirely. For example, Kawasaki’s Z1 only has the sides of its head cover painted silver, which enhances its aesthetic. Chrome plating should be considered based on both the owner’s preferences and the design of the motorcycle. For fully faired motorcycles, chrome plating the head cover doesn’t serve much purpose since it’s hidden.

In terms of functionality alone, avoiding chrome plating is generally the better choice for motorcycles. However, if it’s a visible and decorative part of the bike, chrome plating can enhance the appearance.

Important Note – Points to Consider

[Part 1] Head Cover Types
There are two types of head covers for the CBX1000, as it comes in three models with slightly different head cover designs. You may need to make slight modifications to fit certain covers. The models are as follows:

・CB1
・SC03
・SC06

Only the CB1 has a different head cover shape, while the SC03 and SC06 share the same design. If you're planning to purchase a spare cover for plating, please be aware of these differences. Although it’s not a guaranteed method, CB1 head covers typically lack an engraving on the underside, whereas SC03 and later versions have one.

[Part 2] Types of Chrome Plating
There are two types of plating: chrome plating and sputtering (sputter coating). When ordering from a plating service, confirm the type they provide, as some shops offer both. Sputter coating is a form of plated painting, which has lower durability and tends to peel easily, making it unsuitable for motorcycle parts.

[Part 3] Tachometer Cable Cap
Don't forget to chrome-plate the cap for the tachometer cable as well. Neglecting this part might lead to regrets later on.

[Part 4] Head Cover Bolts
CB1 and SC03 and later models have different part numbers for head cover bolts. SC03 bolts are about 2 mm longer. The CB1 uses 38 mm long bolts for the long type and 32 mm for the short type, while SC03 and later models use 40 mm long bolts and 34 mm for the short. Always check the parts list when ordering, as using the wrong bolts can lead to oil leaks or damage to the cylinder head.

Specific Differences in Head Cover Shapes

The head cover with the number 2 and engravings is the SC03 model. There are also slight differences in the shape of the bolt insertion points. I am comparing the head covers removed from my CB1 and SC03 engines. It’s likely that the SC03 and SC06 share the same design features.

Before Ordering Chrome Plating

I have several head covers on hand. I will choose the previously mentioned CB1 model head cover for the order. I have also placed an order for chrome plating the handlebars.

Finished Product

The items have been completed. The finish is very good. When I placed the order, the delivery time was about two months. I feel that chrome plating the head cover was a good decision. I prefer to avoid customizations that are unrelated to performance. Excessive dress-up modifications are not ideal. However, a little customization can add cleanliness and beauty to the motorcycle.

Installation on CBX1000

As for my CBX1000, the chrome-plated head cover doesn't look bad at all. Since there are many silver reflective parts like the wheels, muffler, and front forks, it doesn't feel disjointed. Outsourcing the plating process often takes time and can lead to missed deadlines. I try to purchase spare parts whenever possible to facilitate my orders.

Customizations involving chrome plating can be divisive. 

Some people believe that
"chrome is poor for heat dissipation."

However, with the layout being conducive to airflow, it shouldn't be a problem. Engine temperature is an important consideration. Make sure to monitor temperatures, especially when waiting at signals with an oil temperature gauge installed.

Once you start repainting or chrome-plating an old bike, it can feel like there's no end in sight. Customizing can be challenging for someone who only has one bike. Additionally, dress-up modifications won't make the bike faster, regardless of how much money you invest. Painting or replacing bolts with new ones can be very satisfying as a custom touch.

When it comes to bolts, please consider carefully where to use stainless steel and titanium bolts.

See you again!
