I ride the same model bike.
The fan comes on around 105-106C.
When it was low on coolant (rad leak) it would come on at 110 and stay on.
An easy solution is to wire up a switch and turn it on manually and keep an eye on the engine temp. ____________________ Spain 2008France 2007Big one 2009 We all die.

Check your coolant levels. Not sure about your bike specifically but the fan switch and the thermostat are not always the same thing or necessarily in the same place. it's possible the coolant level has dropped leaving one or other switch partially uncovered.
Dirty contacts on a temperature sender can also lead to spurious temeprature readings. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

I would say no, that is not normal.
Has it been consistent with the warmer than average weather?
Check the fan/radiator for damage. Check all coolant pipes for leaks, give the pipes a squeeze for any air locks. When was the coolant last fully changed?
Get a workshop manual for your make/model of bike to identify where the relevant sensors are. Give EVERYTHING a good clean and ensure it is in full working order. ____________________ Like a Yorkie - I'm not for the girls |

You usually just need to earth a fan on the switch side for it to come on. Like horns, fans are usually live. So you can have the manual switch in paralell with the standard thermal switch and it will come on with either. If it's this type, the fan switch will only have one wire connected to it. To test the fan, simply short this wire against the head of a bolt on the engine/frame. if there's more than one. Don't do this.
That said, a CBR6 shouldn't need a manual fan switch. Something is wrong with it. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Worth re-checking the coolant level too now you've given it a run. If there is a blowing head gasket, it can pump it straight back out of the expansion tank again. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.
