@@steberg341993 i bought the ktm fan with the readout on it. The cheaper fan without relies on the in bike thermostat and relay. xc models don't have either so the fan would always have to be on or off using a switch. the readout is honestly super nice especially for the injected two strokes since they take so long to warm up properly. worth the couple extra $$, you do need the battery harness for it though.
