Not only does Yu Hirata’s YZ450FM not have a kickstarter, it doesn’t even have a plug where the kickstarter should be. The new cases have been made without the kickstarter assembly. That is a lot of work, time and money not to be put into production for 2018.
The 2018 factory Yamaha YZ450FM up close.
Without looking at the 2017 model you wouldn’t think much has changed with the 2018 factory YZ450FM model. Yamaha didn’t throw the baby out with the bath water. They kept a similar look and its reverse style engine. When comparing the 2017 YZ450F below, you can notice that the frame is much straighter and thicker coming up to the head tube. The engine mounts have moved much father down on the frame. The engine also looks as if it has been tilted forward as well.
