Following the highly successful launch of the official Yamaha Monster Motocross Team for the 2008 season, Yamaha will be releasing a very limited number of 2009 specification YZ450F Yamaha Motocross Team Replica machines for sale to privateer motocross riders.

During 2008, the Yamaha Monster Motocross Team has proved to be the most competitive outfit, and on Sunday 14th September, David Philippaerts won the MX1 world championship in his first season on the factory YZ450FM.
