The chain guard is made from tough Nylon and is suitable, for the Rotax Max and other simular karts. The plastic TAG guard is available in black and you should use the long mounting brackets which keeps the guard more rigidly located and helps move the fixings above the exhaust of the Max making access easier.
The guards are wide enough to allow the use of sprocket protectors. Adjustable mid point to allow the sprocket to run centrally in the guard. Easy to cut and modify to fit most engine / kart combinations
