Enduro2 - WR450F


Heavily based on the World Championship winning YZ450F motocross bike the all-new WR450F features Yamaha’s innovative reverse cylinder head engine and their trademark light-handling, aluminium bilateral chassis.

Benefiting from this advanced engine and chassis technology Outsiders Yamaha Racing Official Enduro2 Team’s WR450F is a high-performance enduro racer ready to take on the FIM Enduro World Championship.

A series of specific modifications bring a further reduction of five kilograms to the team’s racing machine, compared to the production WR450F.
