Additional protection for the valve covers and cylinders of the BMW R 12 boxer is of particular importance as the cylinders of a BMW boxer are exposed. A fall, slip, or scraping against a plastered wall while maneuvering can easily cause mechanical damage up to and including grinding through the valve cover, or at the very least, cause annoying scratches.

Function and Product Features

• Reliable protection of the valve covers against the consequences of tipping over, slipping, or scratching, e.g. when maneuvering in tight spaces
• Reduces or avoids the risk of expensive consequential damage, especially those that would prevent further riding
• Precisely manufactured, contour-accurate with a minimal gap
• Reduces or avoids the risk of the valve covers shifting under impact and the danger of damage to the valve mechanism or cylinder head threads
• 16 mm thick integrated grinding pad, providing protection against grinding through the valve cover in the event of a crash
• Prevents force peaks by evenly distributing occurring forces on three solid mounting points
• Structurally integrated, internal, shock-absorbing segments
• Integrated design that blends into the layout of the motorcycle
• Protector for both the right and left sides, including a mounting kit

Notes

• Our valve cover & cylinder protectors are compatible with both the standard BMW valve covers and the Option 719 valve covers.
• When combined with the GUARD engine protection bar #31472-00X, the extension kit #31475-002 is required.

Reliable: Reliable protection of the valve covers against the consequences of tipping over, slipping, or scratching, for example, when manoeuvring in a garage

The cylinders of a BMW boxer are exposed. A fall, slip, or scraping against a plastered wall while manoeuvring can easily cause mechanical damage up to and including grinding through the valve cover, or at the very least, cause annoying scratches. Since the valve covers are exclusively mounted with friction fit, there is a risk that the valve cover will shift relative to the cylinder head under any impact, potentially damaging the complex valve mechanism or mounting threads. Therefore, additional protection for the valve covers is of particular importance. We have developed a set of highly effective protectors. These are characterised by their precise fit, lying snugly against the valve cover with a minimal gap. This requires precise manufacturing.

The protector is made of high-strength aluminium. Its protective stiffness results from its three-dimensionally bent shape and generous material thickness of 3 mm. On the inside, facing the valve cover, we have integrated segments made of a high-temperature resistant elastic material. These segments are dimensioned to absorb shocks with respect to their Shore hardness*). Their supportive and protective effect ensures that external forces are evenly absorbed by the segments and distributed over three solid mounting points per protector, preventing force peaks. The high-quality design and function of the protectors are complemented by a 12 mm thick integrated grinding pad. In the event of an accident, it serves as protection to prevent grinding through the valve cover and the inevitable oil loss that would result. In this way, the protectors help reduce or avoid the risk of consequential damage. In many cases, they allow uninterrupted riding after an incident. The mounting is simple with the included mounting kit.
