Yamaha WR250F - Enduro 1

Aboard the Outsiders Yamaha Official Enduro Team’s WR250F racing machine, Jamie McCanney secured five class victories and another eight top three results in 2017. Taking his battle for the coveted Enduro 2 World Championship to the very last GP, the Manxman wrapped up 2017 with a solid runner-up class result. For 2018, Jamie will race the updated edition of the WR250F in the revised 250cc Enduro 1 category.

Using Yamaha’s ultra-light and competitive WR250F stock platform the Outsiders Yamaha Official Enduro Team started the development of their 250F machine way back in 2014. Assuming a leading role in the development of the bike since the very beginning has been highly-experienced racer and current Team Manager Marc Bourgeois. Testing the WR250F machine in all conditions Bourgeois has claimed the French Enduro 1 Championship in 2015 and 2016.

With Jamie McCanney having demonstrated his speed and consistency aboard the WR250F machine, the team have their eyes set on battling for the coveted Enduro 1 World Championship in 2018.
