Engine crash bar with sliders – BMW R12 & R nineT

Engine protection bars with sliders – BMW R 12 & co.

The robust and elegant solution to protect your flat-twin, with simplified installation and replaceable sliders

Protect your engine with a solution designed for the real demands of the road. These engine protection bars for BMW R12 (all variants) adopt a redesigned architecture to better dissipate efforts, particularly during frontal impacts. The design directs the load towards high strength fixing points of the frame, instead of relying on simple plates that can deform prematurely.

Made in 304 stainless steel with a 28mm diameter tube and 2mm thick, these crash bars benefit from a multi-step surface treatment (phosphating, electrophoresis, powder painting) for durable corrosion resistance. At the interface with the frame, a nylon sleeve protects the paint and reduces daily vibrations.

Each side is equipped with a machined aluminum slider with precise finishing. In the event of a fall while stationary or a slight slip, simply replace the slider, without having to change the whole thing. The assembly uses exclusively the points of origin, avoiding the removal of important engine bolts: you can install the whole in your garage with complete peace of mind.

Advantages compared to the origin:

✔ Structure directing efforts towards reinforced framework points
✔ Better resistance during frontal impacts
✔ Replaceable aluminum sliders to reduce repair costs
✔ Paint protection thanks to nylon rings
✔ Simplified installation, without intervention on the engine mountings
✔ 304 stainless steel and multi-layer treatment for increased durability

Why improve the original part?

Many original or generic crash bars rely on thick plates (5–8 mm) which become the weak link during an impact. Result: the plate warps, the bar deforms and the protection ceases to be effective, sometimes to the detriment of the engine body.

• Binding plates that bend quickly under load

• Suboptimal force distribution in the event of a frontal impact

• Lack of replaceable sliders, higher repair cost

• Installation sometimes requiring loosening of engine bolts

• Insufficient frame paint protection

This protection bar corrects these weaknesses: the main tube is anchored directly into the high-strength frame points, the aluminum sliders act as consumables in the event of a slight fall, and the nylon ring preserve the finish. You get more protection rigid, durable and economical in use.

Ideal use:

• Daily urban commutes with exposure to low-speed maneuvers

• Travel and tourism, to protect the engine when parking and turning around

• Secondary roads and light off-road connections (Scrambler/Urban G/S versions)

• Aesthetic and functional preparation of BMW R 12/R nineT oriented roadster or classic

• Motorcyclists looking for reliable protection, clean assembly and simplified maintenance
