That is the rear cylinder deactivation indicator. Only comes on when stopped and the ambient temp is above some value, then it goes away as soon as you give it some throttle. You can turn that feature off uf you like in the settings.Did you ever find out what the light means? Mine came on today while riding, it only comes on when stopped and I don't see anything in the manuals.
