Hi. when I turn the ignition on (keyless ride) there is an audible hum from the bike, is that normal? Bike starts no problem and of course can't hear it with the bike running. Been like it since I bought the bike last month , its a 2017 SE model with 6000 miles on the clock

Yes, most likely the ABS pump but various motors energise when you turn on the bike e.g. fuel pump, suspension stepper motors

Hadn't realised there are so many electric "motors". The noise is easily audible. Cheers.

I always thought that the hum was from the fuel pump pressurizing the FI system.

Key on is usually accompanied by a couple of squeaks and then the hum. Could it be the gyro in the bank angle sensor?

I don't think it's gyros, my bike doesn't have gyros (2015) and it still hums.

No hums from my RT, just a not very loud but high pitched noise from the area of the ECU, very similar to my old RS.
