Description BMW R 1300 GS Radiator Guard

The LOBOO CHW131 radiator guard protects both side radiators of the BMW R 1300 GS from stones, insects, and debris. The package contains two panels, one for each side: both radiators are covered with a single purchase.

Honeycomb-perforated aluminum

Each panel is made from 2 mm aluminum alloy sheet with a honeycomb perforation: dense hexagons across the entire usable surface, a solid perimeter frame, and mounting tabs formed from the same piece. It measures 169.2 × 217.9 mm, and the stated weight is 220 grams.

LOBOO calls this geometry “air conduction design” and states that it accelerates airflow toward the radiator, improving heat dissipation. This is the manufacturer's claim, which we report as such: no public source provides a measured value.

Oxidation and sandblasted finish

The surface is treated with an oxidation and sandblasting process, giving it a matte texture that matches the motorcycle's finishes and resists corrosion and washing.

Installation without drilling

It attaches to the mounting points already present on the motorcycle. The manual calls for removing some original components to clear the work area, with reversible procedures: once installation is complete, the removed parts can be refitted. The parts list contains only the two panels, without hardware, because the original fasteners are reused.

The manufacturer advises against fully tightening everything immediately: make all adjustments first, then perform the final tightening using BMW's specified torque values for the original components. Installation is identical on the right and left sides.

Compatible motorcycles

BMW R 1300 GS from 2023 and R 1300 GS Adventure from 2024, with the same code. For the R 1250 GS and R 1250 GS Adventure, the code is CHW082 instead.

Not to be confused with radiator covers: those are the carbon-fiber side coverings that replace the original plastics. They are a different product, are installed in a different location, and both products can be used together.

Why choose it
  • Balance between protection and airflow:the mesh pattern stops stones and insects without hindering cooling.
  • Stiffened edges:prevent vibrations and resonances at highway speeds.
  • Anodized aluminum or stainless steel:depending on the variant, with a finish resistant to corrosion and washing.
  • Mounting on original points:without drilling or modifications to the motorcycle.
Who is it recommended for

It is useful if you ride your R 1300 GS on gravel roads, follow other vehicles in traffic, or ride many miles on the highway: these are the three situations where stones and insects hit the radiator.

A bend or a puncture in the radiator core results in an expensive repair, often requiring complete replacement.

Do not confuse it with the air ducts: those are the side panels that channel the air and replace the original plastic parts. They are a different product and both can be installed.

Documents and manufacturer

Assembly and Notes

  • Fixing on original points, without drilling or permanent modifications.
  • Periodically clean the grille of insects and mud: a clogged mesh significantly reduces cooling.
  • Check tightening after initial use.
  • Verify make, model, and year before purchasing.

How does it work, in detail?

A honeycomb pattern formed in sheet metal

A honeycomb pattern formed in sheet metal

The panel is a 2 mm aluminum-alloy sheet perforated in a honeycomb pattern: tightly packed, closely spaced hexagons, with a solid border around the edges and attachment tabs formed from the same piece.

LOBOO calls this geometry “air conduction design” and claims that it accelerates airflow toward the radiator, improving heat dissipation. This is the manufacturer’s claim, not a measured value: we do not convert it into percentages that no one has published.

Two panels, one per radiator

Two panels, one per radiator

The R 1300 GS has two side radiators, and the package contains two panels, one for each side: the manual’s parts list shows one item for two pieces.

Each panel measures 169.2 × 217.9 mm and is 2 mm thick, and the installation is identical on the right and left.

Two millimeters of aluminum, 220 grams

Two millimeters of aluminum, 220 grams

The sheet is made of 2 mm aluminum alloy: enough to stop a stone thrown up by the wheel of the rider ahead, without weighing down the front end of a motorcycle that is already heavy enough.

The stated weight is 220 grams. The surface is treated through oxidation and sandblasting, with a matte texture that looks good alongside the finishes of the R 1300 GS.

A stone, and the radiator has to be replaced.

A stone, and the radiator has to be replaced.

A bend or puncture in the radiator core requires costly repairs, often involving complete replacement.

All it takes is a stone kicked up by the car ahead or from the surface of an unpaved road: it’s common damage that can be completely avoided.

It also fits the R 1300 GS Adventure

LOBOO lists the CHW131 for the R 1300 GS from 2023 and for the R 1300 GS Adventure from 2024: it is the same code for both.

If you have another GS, this is not the right part: for the R 1250 GS and the Adventure, the code is CHW082. Write to us and we’ll point you in the right direction.

It mounts onto the motorcycle’s existing mounting points.

No drilling. However, the manual calls for removing some original components to clear the mounting area; these operations are reversible, and the removed parts can be reinstalled once the work is complete.

The manufacturer asks you not to fully tighten everything immediately: make all adjustments first, then perform the final tightening to the torque specifications BMW provides for the original components. The manual does not state any torque values of its own.

Don't confuse it with radiator covers

Don't confuse it with radiator covers

On the R 1300 GS, there are two different products: this guard, which sits in front of the radiator and stops debris, and the carbon-fiber radiator covers, which are the side panels that replace the original plastic ones.

They serve different purposes, are installed in different places, and are not alternatives: anyone who wants both installs them together.

Polishing it is part of maintenance

Polishing it is part of maintenance

A grille clogged with insects and mud really does reduce cooling: it’s the only way this product can cause damage.

A visual inspection after long trips and regular cleaning are enough to keep it working efficiently.

FAQs

For more information, please see our FAQ.

Does the cover reduce engine cooling?

The manufacturer claims otherwise: it calls the honeycomb perforation “air conduction design” and maintains that it accelerates airflow toward the radiator, improving heat dissipation. This is a LOBOO claim, not a measured value, and we report it as such. What always matters is common sense: a panel clogged with insects and mud impairs cooling, so it should be cleaned.

Does it fit the R 1300 GS Adventure?

Yes. LOBOO lists the CHW131 for the BMW R 1300 GS from 2023 onward and for the R 1300 GS Adventure from 2024 onward, with the same code. For the R 1250 GS and R 1250 GS Adventure, you need the CHW082 instead, which is a different product.

Do I need to drill or modify the motorcycle?

No drilling. However, the manual does require removing some original components to clear the mounting area; these operations are reversible, and the removed parts can be reinstalled once the work is complete. The manufacturer asks you not to fully tighten everything immediately: make all adjustments first, then perform the final tightening using BMW's specified torque values for the original components.

How many pieces are in the package?

Two panels, one for each radiator: the R 1300 GS has two, one on each side, and installation is identical on the right and left. The manual’s parts list includes only the two panels, without any hardware: reuse the motorcycle’s original hardware.

How much does it weigh, and how big is it?

Each panel measures 169.2 mm wide by 217.9 mm high, with a thickness of 2 mm. The manufacturer’s stated weight is 220 grams; the specifications panel does not indicate whether this refers to a single piece or the pair.

How do you clean it?

With a visual inspection after long journeys and periodic cleaning of insects and mud. A clogged panel is the only way this product can hinder cooling instead of helping it. The manual also recommends periodically checking the mounting screws again.

What’s the difference compared with carbon radiator covers?

They are two different products. This guard sits in front of the radiator and stops stones and debris. Radiator covers are the side carbon-fiber panels that replace the original plastic parts and primarily serve an aesthetic and aerodynamic function. They are installed in different locations, and you can have both.

Is the product covered by a warranty?

Yes: all LOBOO products sold on Endurrad are covered by the 24-month statutory consumer warranty. In the event of a lack of conformity, we will handle the claim with the manufacturer.

Can I return the product if it isn’t suitable?

Yes, you are entitled to return the item within 14 days of delivery under online purchase regulations. The product must be intact and in its original packaging: contact us and we’ll guide you through the process.

How does shipping work?

Tracked shipping throughout Italy: the product is carefully inspected and prepared before leaving our warehouse. The mounting accessories included in the original package are included.

Can I pay in installments?

Yes: at checkout, installment payment services are available directly among the payment methods, with no additional paperwork.

Is it an original LOBOO product?

Yes: we sell exclusively original LOBOO products, new and in the packaging provided by the manufacturer, with official documentation.
