Wunderlich Engine Protection Bar GUARD BMW R 12 nineT - stainless steel

Wunderlich GUARD Engine Protection Bars -

Perfect, effective protection for the engine of BMW R 12 models

Function and product features

• The Wunderlich GUARD engine protection bars for the R 12 models offer the perfect compromise between maximum protection and minimal weight
• Carefully integrated, subtle design that follows the contours of the Boxer engine
• The proven, compact construction ensures high structural rigidity and effective protection
• Reliable protection for cylinders, cylinder heads, and valve covers, reducing the risk of expensive damage to the motorcycle
• Even distribution of impact forces across three mounting points per vehicle side to reduce peak loads and stresses
• No impact on ground clearance or lean angles
• The stainless steel construction provides a striking contrast
• No need to remove the engine protection bars for maintenance work
• Plug & Play fit: easy installation, including mounting hardware and a detailed installation guide

Note and recommendation
Our expansion kit for the engine protection bars (#31475-002) allows the combined installation of the Wunderlich GUARD engine protection bars with:

• Wunderlich valve cover & cylinder protectors (#36611-002) or
• Option 719 cylinder head covers

This shifts both halves of the engine protection bars outward, creating the necessary space for the protectors.

This GUARD engine protection bar offers the perfect balance between maximum protection and minimal weight

During the development of the Wunderlich GUARD engine protection bars, the focus was on achieving the perfect balance between maximum protection and minimal weight.

Its compact geometry provides reliable protection for the cylinders, cylinder heads, and valve covers without compromising ground clearance or lean angles. The two-piece engine protection bar hugs the contours of the engine closely and gains additional stability and rigidity through its specific structure – all while keeping weight optimised. The bars on the right and left sides are securely bolted to three pre-existing mounting points on each side. In the event of a fall or crash, the forces are optimally distributed across the protection bar structure and onto the robust mounting points, minimising peak loads and reducing material stress. This proven all-around protection concept increases passive safety and enhances riding confidence.

The engine protection bar structure is made from 25-millimetre precision stainless steel tubing. The tubing segments are shaped on CNC pipe bending machines and then cleanly welded.

Visually, the protection bar integrates seamlessly into the motorcycle’s design, complementing its distinctive look. The high-quality stainless steel construction enhances the appearance of the R 12 models with a striking contrast.
