• Real Protection: A laser-cut 1.5 mm aluminum guard stops rocks, sticks, and debris from puncturing your radiator before they can end your ride.
• Airflow Preserved: Each louver is sized to block debris while keeping air flowing freely to the radiator, so your engine stays cool on hard trails.
• Rigidity Built In: Louvers add structural stiffness to the guard itself, and 14-gauge stainless steel flanges handle the long reach to the recessed mounting points.
• Radiator Clearance: The guard sits at least 12.7 mm away from the radiator face, creating an air gap that further supports cooling even when the guard is taking a hit.
• Simple Install: Mounts with included hardware and no modifications required.
• Material: Laser-cut aluminum (guard); 14-gauge stainless steel (flanges)
• Thickness: 1/16 inch (1.5 mm)
• Finish: Anodized silver or anodized black
• Radiator Standoff: Minimum 1/2 inch (12.7 mm) from radiator face
• Hardware: Included
• Weight: 0.7 lbs
• Dimensions: 16 × 12 × 1 in
BMW F 750 GS (2018-2026), BMW F 850 GS (2018-2026)
A punctured radiator ends your ride and can end your engine. On rough trails, rocks and sticks find the radiator fast. This guard stops them before they get there.
The louvered design is not a compromise. Each louver was sized after careful study to block debris while keeping airflow unrestricted. The louvers also stiffen the guard itself. The guard sits a minimum of 12.7 mm off the radiator face, keeping an air gap even under load.
The mounting points on the F 850 GS sit deep and recessed, so AltRider used 14-gauge stainless steel flanges to bridge that reach without flex. Installation uses the included hardware with no modifications to the bike.
Compatible with the BMW F 850 GS and F 750 GS in Standard and Rallye trim. Available in anodized silver or black.
• Radiator Protection: Laser-cut 1.5 mm aluminum plate blocks rocks, sticks, and road debris from puncturing your radiator.
• Airflow Preserved: Each louver is sized to deflect debris while keeping enough air moving through the radiator to prevent overheating.
• Standoff Design: The guard sits at least 12.7 mm away from the radiator face, leaving a clear air gap for cooling even on slow trails.
• Easy Install: Mounts with included hardware — no special tools or modifications required.
• Material: Anodized aluminum
• Thickness: 1/16 in (1.5 mm)
• Radiator Standoff: Minimum 1/2 in (12.7 mm)
• Weight: 0.7 lbs
• Dimensions: 16 × 12 × 1 in
BMW F 850 GS (2018-2026)
A punctured radiator ends your ride — and replacements are expensive. This guard puts a solid barrier between your radiator and whatever the trail throws at it, whether that's rocks, sticks, or kicked-up road debris.
The louvered aluminum is precision laser-cut to balance protection and cooling. Each louver is sized after deliberate study — enough coverage to stop debris, enough open area to keep air moving freely. The guard is also held off the radiator face to maintain that airflow gap even at low trail speeds.
Available in silver or black anodized finish. Both are durable and built to handle the same conditions you ride in.
• Radiator Protection: Laser-cut aluminum guards the radiator from rocks, sticks, and road debris that can puncture cooling fins and end your ride.
• Airflow Preserved: Louvered design and a minimum 1/2-inch gap between the guard and radiator face allow cooling air to flow freely so the engine runs at the right temperature.
• Added Rigidity: The louvered pattern stiffens the entire guard, so it holds its shape and keeps protecting even after repeated impacts.
• Lightweight Build: 1/16-inch anodized aluminum keeps the guard strong without adding unnecessary weight to the front of the bike.
• Quick Install: Designed to go on easily with included Loctite and first class manual
• Material: Aluminum
• Thickness: 1/16 in (1.5 mm)
• Finish: Anodized — silver or black
• Radiator Standoff: Minimum 1/2 in (12.7 mm)
• Weight: 0.7 lbs
• Dimensions: 16 × 12 × 1 in
BMW F 850 GS (2018-2026)
A punctured radiator ends a ride immediately. In remote terrain, it can end a trip entirely. The AltRider Radiator Guard for the BMW F 850 / 750 GS puts a purpose-built barrier between your cooling fins and whatever the road throws at them.
The louver size was determined after thorough testing — large enough to block sticks and rocks, shaped to avoid restricting the airflow your engine needs. The guard mounts with a minimum half-inch standoff from the radiator face, which adds another layer of airflow protection on top of the louvered coverage. The louvered pattern also stiffens the guard itself, so repeated impacts do not deform it over time.
Anodized finish holds up to weather and debris. Included hardware covers everything needed for installation.
