Takegawa oil temp thermostat for the CRF50 CRF70 KLX110 special die cast magnesium and aluminum manual clutch covers allows your engine to heat up to optimal temperature before opening and allowing oil to pass through to your oil cooler. Shape memory alloy spring allows rapid response to temperature change, only allowing oil to pass through to the cooler above 70 degrees C. When closed, oil is forced through a return passage directly to the engine.

Note: Previous blue versions of this thermo unit have been discontinued
