BMW cylinder head protectors
There are various options available for BMW cylinder head protectors, ranging from plastic guards to stainless steel covers. Plastic guards, such as the MAM Cylinder guards, are effective in protecting the cylinder head and can be easily replaced if damaged. These plastic guards are also available in tough plastic options, like the MaMo head covers, which feature a rubber shock-absorbing liner. This liner helps to absorb impacts and can withstand minor scuffs and marks from tipping over or sliding.
Stainless steel cylinder-head cover guards, on the other hand, offer excellent protection and are known to prevent scratches and damage. BMW offers a stainless steel guard with a large rubber bumper that perfectly matches their motorcycle models, emphasising the design and contours of the boxer engine.
BMW also offers the Rocker Cover Protectors, made from high-quality materials for long-lasting durability. These protectors are designed for specific BMW motorcycle models, ensuring a perfect fit and maintaining the unique BMW style. They protect the engine from scratches, impacts, and gravel, and come with a 2-year warranty.
When choosing cylinder head protectors, it's important to consider your riding conditions and requirements. For off-road riding, you may need different protection than for on-road or track riding. Additionally, some riders prefer the use of crash bars or engine guards in conjunction with cylinder head protectors for added protection. However, it's worth noting that engine guards may not always be effective in protecting the cylinder heads during a tumble or heavy impact.

BMW cylinder head cover repair
BMW cylinder head covers are made of plastic and are prone to damage. They can be repaired rather than replaced, depending on the severity of the damage.
If the damage is merely cosmetic, with scratches or scuffs, the repair is a relatively straightforward process. The first step is to smooth out the scratches using a fine double-cut file and a single-cut file. This process will help to remove any deep gauges and create a more even surface. The area can then be inspected using scotch brite and 800-grit wet sandpaper to check for any remaining imperfections. Once the surface is smooth, the next step is to bead blast the exterior to prepare it for painting. A suitable paint colour should be chosen, such as asphalt grey, and a clear top coat may be required, depending on the type of paint used.
In some cases, the cylinder head cover may be warped or cracked, and it is important to assess whether the part is still functional. If the damage is extensive, it may be necessary to replace the entire cylinder head cover. The cost of a new cylinder head cover can vary, with prices around £200 in the UK and US$398 in the US.
To prevent future damage to the cylinder head cover, some BMW owners opt for additional protection such as engine guards or cylinder head protectors. These guards are available in plastic or metal and can help to absorb impact and protect the cylinder head during a fall or collision.
It is important to note that repairing or replacing the cylinder head cover may require knowledge of automotive repair and painting techniques. For those unfamiliar with these processes, it is recommended to consult a professional or seek advice from experienced BMW enthusiasts and forums.
