Rock Machine is an international motorcycle cub founded by brothers Salvatore and Giovanni Cazzetta in Montreal, Canada in 1986.
The club is infamously known for warring with the Hells Angels between 1994 and 2002.With over 160 deaths, and countless injuries from both sides, the 'Quebec biker war' is the most deadly biker war in history.
After the Quebec biker war, Rock Machine aligned itself with the Bandidos. In January 2001, the majority of Rock Machine decided to patch over to the Bandidos.
In 2008, the original RM brothers decided to come together and resurrect the club. The Rock Machine were back bigger and stronger. The club has since expanded across the globe and is now one of the largest motorcycle clubs in the world.
