    Race thermostat

    Hi, I’ve been looking for a ‘race thermostat’ or low temperature thermostat as I’m wanting it to aid keeping the engine temperature below 90. I use it on track and run with out a cooling fan. Has any one had experience in this as I can’t find anything online. I do plan to change the radiator too.
    Bike is 2015

    I m just waiting on the radiator price as the higher pressure cap comes with them I think. I couldn’t find the thermostat on alpha racing though

    Don't think they sell them, tbh never seen a race thermostat.

    There is race radiator if you have deep pockets, there is high bar pressure cap, but never seen a thermostat.


    Are you based in exotic hot country ?

    I run 92-94C on Gen4 at Mugello in 30C ambient summer. Bike works perfectly fine.

    Sunny uk.... some might call it exotic hahahah. 1st time out this year at snetterton ambient temp was low around 6C but bike was around 94 when I came in. I know the manufacturer likes to run high temperatures to help with the emissions

    fan on a track bike is pointless apart from maybe when your held in pitlane,other than that will make no difference to yor bikes running temp.

    Totally

    94 when you come in is not a big deal as you shut it off straight away
