My wife's ST2 is a bit newer than mine, Mine was from the first shipment, hers was bought from a later batch. I've noticed a couple of differences. On mine whenever I change the back tire or rather remove the back wheel, I have to replace the ziptie that holds the wire bundle away from the disk rotor. Hers has a built in metal wire guide so no zip ties needed. As we were riding today I noticed her front LCD lights were off. When we got home the first thing we did was run the updates that had just downloaded(on both bikes). Then when I tried to turn on her lights I realized the Main Menu looked different from mine and did not include light controls along with the lcd controls. On my bike the second option is LIGHT/LCD, on hers it's just LCD. Any ideas how I can turn the light on?
