The 2008 Yamaha YFZ450 is the “civilian” version of the “war” R model: a zero-compromise, no-jokes sport quad, built for top performance on the dirt track. It boasts the same combination of aluminium and steel elements for the chassis, thus improving cornering and shaving off unnecessary weight and boosting the rider's confidence. Nitrogen-charged front shocks provide long travel for comfort in the most demanding of situations, while the motocross-derived linkage swingarm offers even more room for movement.
Electric start and eccentric chain adjuster for on-the-fly tuning are premium features when it comes to convenience, while the parking brake is a valuable addition for after-race peace of mind.
