  • Mylers Aluminum Radiator

    Mylers Aluminum Radiator

    Adam in CO

    Stronger than OEM but horrible fit

    This radiator is obviously more stout than the OEM radiator, but the fit leaves quite a bit to be desired. The radiator cap barely clears the tank and the overflow nozzle is way too long to clear the tank. The overflow nozzle did however shear right off when I tried to unscrew it. On top of the poor fitment the threaded plug for the radiator shroud to bolt to immediately came loose and spun, making it extremely hard to bolt on the radiator shroud. This radiator seemed like it was not designed for the KTM and was simply slapped on as an after thought.

  • Works Connection Aluminum Radiator Braces

    Works Connection Aluminum Radiator Braces

    Justin in NV

    They're okay.

    I've tried Works connection, Devol and Enduro Engineering. By far I am most impressed with the Enduro Engineering radiator cages. These Works Connection braces are better than nothing, but the cages are the way to go.

    KTM Radiator Fan Kit

    I have lost no coolant since I put the fan on. It seems to come on when it is needed. It works like it should.
