The cylinders on a Boxer BMW are exposed. Stone strikes, falls on terrain or when scraping a plastered wall as you manoeuvre in tight spaces make it easy to scratch the valve cover. On the 1250s shift cam engines there's also the issue that the construction of the shift cam mechanism is extremely elaborate. Since the valve covers are mounted solely using force locking, there is a risk that the valve cover can be displaced relative to the cylinder head after any violent impact and the elaborate valve drive can be pulled along with it in certain instances. This is why the additional protection of the valve cover is of particular importance.

We have developed a set of well-designed protectors for this. These are characterised by the fact that they sit on the valve cover with narrow gap dimensions and accurately fit the contour. This requires precision manufacturing. The protector consists of impact-resistant, durable plastic. On the inside which faces the valve cover, we have constructively integrated segments with an elastic material that is resistant to high temperatures. These segments are dimensioned to be impact-absorbing in terms of Shore hardness*). Its equally supportive and protective effect ensures that external forces and moments, when applied, are evenly absorbed and distributed across the segments, thereby avoiding force spikes. The high-quality design and the function of the protectors is rounded off by an inset stainless steel insert. Even though primarily decorative in nature, it serves as an additional protective element in case of unforeseen circumstances, further reducing the risk of valve cover abrasion and the associated oil loss. In this way, the protectors contribute to reducing, ideally avoiding, the risk of secondary damage. In many instances, they let you carry on riding after the mishap. The assembly kit provided makes assembly easy. Our valve protectors are Made in Germany. That's why we're happy to provide a 5-year warranty.

Please note:

Our valve cover & cylinder protectors are only compatible with the standard BMW valve covers.
