    Description


    Wunderlich ULTIMATE Engine Protection Bars

    Available in: Black or Red

    These Wunderlich ULTIMATE engine protection bars have been specifically designed for adventure riding.

    They provide reliable protection not only for the cylinders and valve covers, but also for both lambda sensors. This comprehensive protection concept enhances passive safety and, with it, riding enjoyment. In the event of a crash or the motorcycle tipping over, the forces generated are optimally distributed through the protection bar structure to the robust mounting points. This prevents peak loads and torque stresses, effectively reducing mechanical stress on the components.

    The engine protection bar structure is manufactured from 25/22 mm precision steel tubing. The tube sections are formed using CNC tube-bending machines and then cleanly welded together. Visually, the protection bars integrate seamlessly into the motorcycle's design, complementing its distinctive appearance. Our ULTIMATE engine protection bars have also been designed with ease of maintenance in mind: The oil drain plug and oil filter cartridge remain fully accessible for an oil change, without having to remove the engine protection bars.

    With our protection bars, protective performance and product design are our top priorities. The engine protection bars enhance your BMW with a premium-quality finish. The surface features a Blackpowder coating.

    Function and product features
    • Wunderlich ULTIMATE engine protection bars are uncompromisingly designed to provide maximum protection for adventure riding – including for the BMW R 12 G/S, which has established itself as an adventure bike alongside the R 1300 GS
    • Maximum protection thanks to additional structural braces that significantly increase the rigidity of the protection bars even further
    • Optimum protection for the cylinders, valve covers and both lambda sensors reduces the risk of costly damage to the motorcycle itself
    • Even distribution of forces across four mounting points on each side of the motorcycle
    • The bars are precisely shaped to follow the contours of the boxer engine
    • No reduction in ground clearance
    • Maintenance-friendly: The engine oil and oil filter cartridge can be changed without removing the engine protection bars
    • Plug & Play fit: Straightforward installation with detailed fitting instructions included
    Compatibility
    • In addition to the BMW R 12 G/S, the Wunderlich ULTIMATE engine protection bars also fit the BMW R 12, R 12 S and R 12 nineT.
