BILATERAL BEAM ALUMINUM FRAME
The new YZ450F features a lightweight, Bilateral Beam Frame with over 16 different pieces made up of Extruded, Forged and Die-Cast Aluminum. Developed with the goal of being the ultimate cornering motocross bike the unique double S-bend shape of the frame plays a key role in the positioning of the new engine layout as well as the overall nimble handling feel of the bike. Hitting inside lines, carving through deep ruts and making quick direction changes are no problem for the 2010 YZ450F new chassis.
Yamaha prides itself on great out of the crate suspension and the 2010 YZ450F features the same KYB SS Forks that have garnered much of that acclaim. To work with the new chassis the forks have been lengthened 10mm and re-valved with a new dampening character.
The KYB Shock features a new Piggyback design thanks to the additional room that the new engine layout allows. The shock is now centrally mounted in both the bilateral beam frame and swingarm, which allow for the shock to better absorb the rigors motocross throws at it.
SIMPLE SERVICE ACCESS AND RIDER COMFORT
The all-new YZ450F has the benefit of years of Yamaha Factory Racing experience – one resulting highlight is simple race prep and service. Common bolts and nuts are used from most engine and plastic parts. The oil tank is integrated with the crankcase so servicing the engine is a snap.
The YZ450F also boasts ProTaper® handlebars with four-position adjustability, allowing riders of any size to find a comfortable setting. The seat design is very flat, allowing plenty of freedom for the rider to be able to slide back and forth to get in the right body position on the bike.
The new YZ450F comes in a standard color Team Yamaha Blue/White or in a second color White/Red.
