@swapmoto went to Japan last weekend for the All Japan National MX Championship Series opener and was able to catch some video footage of the pre-production 2018 Yamaha YZ450F. CLICK HERE to see the photo report that went up earlier.
The Yamaha team was very secretive about the YZ450FM, which was all new. The team kept the bike beneath a bike cover when it was out in the open, and the team pit area was shrouded with opaque plastic windows which made it impossible to get a clear view of the bikes inside. Of course, there was no hiding the bike when it was being washed in the official wash bay, so that’s where we pounced with our GoPro Hero5 Black!
