Riding a production-based YZ250F, Tony Cairoli’s phenomenal
record in the 2007 MX2 series underlines this awesome bike’s
unbeatable potential.
Running a higher 13.5:1 compression ratio, and offering lower
reciprocating weight and reduced frictional losses, this GP-developed
design allows the high-revving engine to run even harder and faster.
And to handle the extra performance we’ve fitted an uprated
clutch with an increased oil supply. New lightweight forks deliver
quicker turning – and a revised linkage and new shock settings
ensure superior handling and even quicker lap times!
