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
- Black colour perfectly matches the black frame
- 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.
