Details are hard to come by, but it is known that Anthony Gobert's on-again, off-again girlfriend Sunni Dixon was killed last week in a car accident in Southern California. Dixon was well known in the Superbike paddock since the late 1990s when she hung out with the Harley-Davidson Superbike team.

Little is known about Dixon's death at this time, other than she was killed in a car accident and leaves behind two young sons.

More info as it surfaces.
