I didn't know what a milk float was - thanks for the education!
Back on topic - I can't imagine my transmission making any noises that I would associate with that vehicle, so I'd say - no, it's not normal. But, it's possible that we need to look into the noise and maybe do a better characterization to get to the bottom of this.

Stephen, this vid may not be a good example due to the loud race pipe but if you listen closely you can hear the gears winding as he's gearing down. Is this sort of like you hear? A 'blip' of the throttle to match the engine and transmission helps smooth out downshifts if this is what you hear.
Put it on a rear stand, start it, and see if you can isolate it by placing the end of a flexible tube to your ear, and the other end to various parts of the bike. A member here turned me on to that trick. Like a stethascope for a doctor.
but I'm gessing it's the electric cooling fan that comes on when the bike gets hot.
I think it's the sound you hear when downshifting at speed with the clutch pulled in. Mine does it when you get to first gear and are still coasting to a stop. I have had several bikes in the past that did the same thing so if that is what you are hearing, then it's normal.
