DIY Motorcycle Radiator Guard Material

Updated July 20, 2017

Radiators are devices that transfer heat from one area to another. In motorcycles, and most other vehicles, the radiator is a necessary part of the vehicle's function. The radiator is often left exposed on a motorcycle, given the structure and size of the vehicle. To protect you from the radiator, a radiator guard with holes to vent air will often cover the device. These guards can be expensive, but the do-it-yourself person can build a radiator guard for only a few dollars, saving tens if not hundreds of dollars.

Measure the area to be covered around your radiator with a ruler.

Mark the dimensions of the area on the stainless steel mesh with a ruler and a marker. Cut the stainless steel mesh using the wire cutter. You should cut slits in the mesh so that it fits snugly and around other objects on the bike. If you do this properly, the radiator guard will slide into place and may not need any fasteners.

Fit the edges of the stainless steel mesh with sheet metal edging. The edging will either self-grip or you may need to tighten it with needle nose pliers. The edging will protect you and your bike from the sharp edges of the mesh.

Fit the radiator guard to the bike. If you do this properly, you will not need to do any bending.

Cut thick wire to form a fastener if the radiator guard feels loose. Tie the wire to the radiator guard and to an unnoticeable spot on the bike.


Secure the radiator guard by adding multiple fasteners. Try different colour mesh for a different look.


Make sure the bike is off and has been off for a while when fitting the radiator guard to avoid burning yourself.
