Yamaha WR450F 2016

In addition to introducing a new two-stroke model, Yamaha has updated its flagship 4T enduro, the WR450F. The motorcycle used the YZ450F motocross engine layout with the cylinder turned back and the intake and exhaust turned 180 degrees. The engine is housed in a new aluminum frame based on the aforementioned YZ450F.

Stoner explains the tank slapper

Casey Stoner looked all set to win at Motegi, after translating his pole position into an early race-lead. But coming over the crest on the back straight his bike momentarily lost control in a tank slapper. Regaining composure the championship leader was forced to pump his brakes to get the pads back in place, with the rear-wheel bouncing in the air he ran out of time and space to make the 90 degree right hander and was forced to run into the gravel.

No snow here folks!

An erratic work schedule combined with a full season of kids racing means, there aren’t many opportunities during the summer months for the Mackenzie family to grab a holiday. Instead, we tend to save our pennies and head off somewhere sunny for Christmas. I love doing this as it shortens the UK winter but more importantly it means I miss the festive frenzy.  I do like Christmas, but I hate how everyone gets caught up in the retail madness that kicks off just before Halloween, then has everyone stressed (and skint)before Santa has even hitched up his sleigh.
