Yamaha’s once-popular YZ450F has been slipping in the polls of late, a situation the factory seems bound to rectify with this newest version that should propel it back into the top tier in the motocross world along with Honda, KTM, and Husqvarna. The 2018 YZ450F sports updated looks to go with its updated features such as the new engine, wireless engine tuning and improved suspension just to name a few. A teeny-tiny battery and lightweight starter system eliminates the old kicker (and the peasants rejoice!) with a new push-button cold-start feature that helps with starts and warmups. For all intents and purposes, this should be considered an all-new machine, so let’s check out what Yammy has going on over there and see how it stacks up against the other big boys.
