This kit is for 2017-2019 KTM450/500 XC-W and EX-C models, as well as the 2017-2019 Husky FE450 and FE501 These are some of the most popular bikes used in the snow, and even have a factory plastic thermostat housing with bypass – but they still run cold because the thermostats are 158°F and don’t totally close off radiator flow when below rated temperature. This is because they have a large bleed hole in the thermostat that is fine when used as a dirt bike, but on a snow bike it becomes an issue as you just can’t afford to send that much coolant flow through the cold radiators. The Thermo-Bob 4 is an aluminum housing with a 180°F (82°C) thermostat inside, has different temperatures available as options, and has a port for a temp sensor with a 1/8 BSPP thread. The aluminum Thermo-Bob 4 fits in place of the factory plastic thermostat assembly. A full technical write-up when used on a Kawasaki KLR650 can be found .
