I had just started trials riding on a bright orange KillerV600, model '96, customised with DH bars and high rise stem. Then I replaced every single bit that failed. The KillerV600 frame cracked after four months and was replaced with a KillerV800 frame (the nicest frame ever...but a weld on the back sloping tube cracked after about two years and a half of abuse).
