    It's Cool (ing)

    Great service. Product arrived quickly. Easy install. Does exactly what it's advertised to do. The bike runs much cooler. It hasn't gotten above 7 bars on the coolant gauge whereas it used to go to 10.

    This thing turns the fan on sooner than the stock version. A great upgrade helps the bike stay cool. A must have for So Cal temperatures !! 5 stars. !

    Thermostat sensor upgrade

    It worked perfectly the engine temperature dropped to the middle instead of keeping a three quarter and plus so the thermostatic fan is much more active and does the work.

    Thermostat switch

    Let’s my KTM run cooler, which is always good, especially on hot days with slow technical trails. Yes, the fan runs more often and will often start even after the engine has been off for a bit, but that doesn’t bother me. My engine temp has never exceeded 7 bars since installing. I’m pleased.
