The "Radio Knob Mod" mentioned above is simple. Get TWO keys made and the two Knobs Here...I say two keys so you can "Mod" one for the glove compartment key lock that's just as annoying.

Measure the keys when inserted into each lock and cut so you still have enough key to glue inside the knob. Glove compartment key needs to be longer and this key CAN be used in the ignition to unlock the front forks, but won't start the bike.

If I'm feeling cautious, I'll pull the keys out and drop them in the locked tray under the gas tank cap lid.
