Yamaha’s 2012 model YZ250F now available in Australia

Heavily revised Yamaha YZ250F has been released in local dealers.

Yamaha has announced that its new 2012 model YZ250F is now available in Australian dealers.

The world’s first modern era four- stroke 250cc motocross bike has copped a host of revisions aimed at placing the new model at the top of the winner’s rostrum.

Following a successful press launch at Stanmore MX track in QLD, the new YZ250F hits dealers showrooms today with a revised frame, engine and suspension offering a lightweight, sharp handling package.

The 2012 YZ250F has revised frame, front end geometry, engine and suspension. The result is more mid to top end power with sharper turning and increased stability.

Yamaha’s YZ250F retains its carburettor design which is one of the main reasons for this model retaining its status as the lightest bike in the 250cc class. However, the carb size has been beefed up to 39mm and the optimised engine pumps out more power in the 8000 to 12,000 rpm range.

This increased hit combines with outstanding throttle response thanks to new crankshaft webs, a new vibration-reducing counterbalancer, new connecting rod, and low-friction piston rings – as well as a new piston, piston pin, and clip assembly.

The piston setup alone is over eight lighter overall than before. The lighter piston spins up superbly and minimises friction- based power losses.

To take full advantage of these advancements, there’s also a new CDI mapping and the bigger 39mm carb breathes freer thanks to a larger air cleaner cage.

Added to the new frame and suspension refinements, this latest engine gives YZ250F amazing balance – a powerful, light-handling and sharp handling machine that appeals to pro riders but is also easy to ride.

The new-for-2012 Bilateral Beam frame has revised rigidity balance for superior cornering performance as well as great stability on rough, high- speed straights.

Beefy new front KYB suspension components plus revised rear shock internals and more rigidity in the swingarm axle block area give this new machine a serious handling advantage with light, quick steering and zero headshake.

Despite the large number of revisions, the 2012 model YZ250F goes on sale today at the same price as the outgoing 2011 YZ250F.
