  1. Hi,
    I am mainly just bored atm...buuuut

    I have noticed that my CBR125R, when I am warming it up (2005 model), when I turn the throttle the headlights become brighter, and when I release they dim. This normal?
  2. Yep, totally normal.

    It's just the increase in voltage from the alternator as the revs rise
    (that's what charges the battery).
  3. Thanks.

    Iwas worried about the battery as it was just replaced.
