YAMAHA MOTOCROSS BIKES, 2018

Yamaha announced its 2018 motocross line today and it’s highlighted by an electric-start YZ450F with an all-new motor and frame.

Virtually every part has been redesigned even though the configuration is still easily identified as a Yamaha because of the rearward tilting cylinder and reverse head.  Here are some of the official words from Yamaha:
