RX4 overheating

I appreciate if some would shed a light. I suspect a loose fan cable connection or faulty relay? Thanks

My bike does this too, luckily for me I rarely encounter traffic.... Wounder if its the thermostat as well or like you say the relay..... Need to contact CSC and see what they say...

Thinking could be muffler bearing?

So have you checked the fan connection?
