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 1250’s 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.

When impacted by exterior forces, their equally supportive and protective effective ensures that these are absorbed and distributed equally across the segments and force spikes are thus avoided.

The high-quality design and the function of the protectors is rounded off by an inset stainless steel insert.

In the worst case scenario, it protects against grinding of the valve cover and thus avoids the inevitably associated loss of oil.

The protectors thus contribute to avoiding 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 only fit with the BMW standard valve covers.
