High speeds on the open road may be easier to enjoy on a motorcycle, but without the proper protective equipment on your bike, you could be risking the service life of your vehicle. Without a radiator guard, one well-aimed pebble projected upwards from the road by your wheels can take a radiator out of commission. Radiator guards also cut down on the dirt and mud that can build up around your radiator and weaken performance. Instead of purchasing a brand name guard for a few hundred dollars, you can quickly create and install your own for less money.

  1. 1

    Cut a piece of steel wire mesh large enough to fit across the opening exposing your bike's radiator with tin snips. Steel wire mesh can be purchased from a metal cutting service or an auto parts store specialising in grille customisation. Do not worry about cutting the mesh piece too large as it can be folded back onto itself to save space.

  2. 2

    Place the steel wire mesh over the opening to the radiator. Sometimes, a bike has a radiator shroud in this position for cooling purposes. If there is no radiator shroud, make sure that the distance between the mesh and the radiator is at least 30 millimetres during installation.

  3. 3

    Attach the homemade radiator guard to your bike. If your motorcycle includes a radiator shroud, use cable ties to secure the centre and sides of the radiator guard to the shroud. Bikes without a radiator shroud will have holes to accommodate mounting bolts for a shroud or guard. Use tin snips to cut a hole or incision large enough to accommodate the bolt. Thread a washer over the bolt and then use a socket wrench to tighten the bolt into place. Reference your motorcycle owner's manual for more information about compatible mounting bolt sizes.

  4. 4

    Fold any excess mesh material around the perimeter of the steel wire mesh backwards onto itself. Use pliers to prevent steel points from breaking your skin.
