Wunderlich Engine Protection Bar PRO for the BMW S 1000 XR - shines with remarkable technical solutions
Function
- The two-piece engine protection bar offers maximum protection and maximum ground clearance with minimal weight
- Slim, integrated form, functional design
- Easy mounting without the need to enlarge or modify existing openings in the fairing
- Simple retro-conversion, since the faring doesn’t need to be modified
- Special silent bearing for vibration-decoupled, form-fitted attachment
- Thus avoids the undesired transferral of vibrations and coupled fluctuations
- The rubber ring elements used in the silent bearing absorb additional energy in the event of a fall or crash
- Simple assembly, incl. the necessary assembly materials
- The original auxiliary light can be mounted on our PRO engine guard using the mounting holes prepared for this purpose

Maximum protection. Maximum lean angle. Minimum weight.
Our two-piece engine protection bar for the S 1000 XR offers maximum protection and maximum ground clearance with minimal weight. Its slim form integrates harmoniously into the design layout and the contours of the new, large XR.
It shines with two more noteworthy technical solutions in the process:
unlike the original protection bar, in our design, the faring doesn’t have to be notched on the upper attachment point on the frame side. The geometry of the protection is designed so that the faring doesn’t need to be cut out to screw it to the frame. Notching or cutting out the faring comes with the risk of damaging the faring so that it may end up requiring costly repainting. All this is eliminated with our protection bar! This lets you easily retrofit the engine protection bar, because is the original shape of the faring is retained.
Special silent bearings for the protection bar of the S 1000 XR
A second significant point is the special, vibration-decoupled attachment of each of the engine protection bars on the top of the frame bottom of the engine. On the frame side, the bar screws on as normal. On the engine side, we use specially developed silent bearings. The lower ends of the engine protection bar are both inserted axially into the silent bearing.
The three-part silent bearing consists of the aluminium bearing screwed to the engine housing and two internal O-rings. An O-ring is positioned inside the bearing for decoupling of vibrations and as an impact absorber. The second is for radial guiding. The Shore hardness of the O-rings is determined such that despite this decoupling, the secure, form-fitted positioning of the engine protection bar is guaranteed.
This decouples the bar - which is screwed to the frame - from the engine in terms of fluctuations and thus avoids the undesired transferral of vibrations and fluctuations.
In the event of a fall or crash, the protection bar rests on the internal stopper of the silent bearing above the O-ring, which works as a fluctuation and stop damper, and absorbs the resulting axial forces. The second O-ring absorbs the radial forces and absorbs additional energy.
