Umm, are you meaning the relay in your head that is supposed to tell you not to try to restart your car/bike ?
 ;)

The relay, a diode, and the clutch & neutral switches are there to prevent the starter motor from running
when the driveline is connected to the crankshaft so that you don't press the starter button and launch the bike
out from under you, or off the sidestand.

Makes an interesting sound, doesn't it?  ;)

greetings from a warm and sunny north - we are expecting temperatures up to 86 F this weekend which means that the roads and tires are warm and good for narrow turns at 50 degrees  :) Not the turns but the angle of the r65 from the vertical position when going round the turns

LOL! I do that on occasion with my car, too. Irritating noise and a reminder, "Note to self: Engage brain before operating equipment."  :-?

Beemer, I think you can tell from all of the "hints" dropped here that this is "normal" operation.  I suppose you could rig a circuit that would prevent this this such as looking for oil pressure or ignition pulses, but I guess the engineers felt the operator needed to have  something to do!  ;)

My mid-80's Japanese bike would - a friend of mine really pissed me off one time as he repeatedly stabbed the starter button, thinking it was the
horn.   But, the Japanese starter had a well made, fast-acting over-run clutch, better than in the Bimmer.

I used to do it when the button would hit a loaded tank bag while on a trip.

Now I have accessorized myself beyond full-lock! ;)

(leg shields and G/S handguards.)
