YZ450F - Undisputed MX1 class leader
With Josh Coppins leading the '07 MX1 series - and the bike's unrivalled track record from '06 that includes winning 27 out of 30 heats - the YZ450F is officially today's most successful MX1 bike!

For 2008 season the undisputed class leader's engine gets a number of significant improvements - including reshaped intake ports and cam profiles, reduced piston tolerance and modified transmission backlash. And the YZ450F's lightweight aluminium chassis runs with a shorter headpipe, lighter forks, compact new front caliper, and modified rear suspension - which makes the 2008 bike accelerate better, turn quicker and feel lighter, for an even more dominant package!
