Bike: 2018 Yamaha YZ250F

Latest Yamaha MX2 offering revealed internationally.

Yamaha’s 2018 YZ250F, the latest edition of the current Australian Motul MX Nationals MX2 championship-winning machine, was today revealed internationally.

Remaining mostly unchanged for the new year, the 2018 Yamaha YZ250F features a host of tried and tested features to ensure yet another highly-competitive 250cc four-stroke model.

Using the unique reverse cylinder design, the 2018 Yamaha YZ250F features a high lift cam profile as well as large diameter intake valves and strong valve springs.

Fitted with a big-bore front exhaust, this advanced power-boosting head offers strong mid-to-high rpm pulling power for an advantage from the drop of the gate.

Using a short intake funnel, combined with a throttle joint that gives a five percent larger opening into the raised intake port, this highly efficient design allows for more power on-track.

To handle the power of the 2018 YZ250F, the transmission features wide teeth and modified dogs. These combined with the shift cam and clutch activation offer smooth, quick and positive shifting.

The ECU, using optimum ignition and fuelling map settings along with a high rev limit provide an impressive over-rev feeling and competition feel.

Housing the strong 250cc, liquid-cooled, DOHC, four-valve engine is an aluminium beam frame. This frame design has been refined with a wider area behind the swing-arm pivot point giving higher torsional rigidity for increased stability.

Steel engine mounting brackets are also featured to enhance rideability, and the foot-pegs provide a roomier riding position and a lower centre of gravity.

In the suspension department the 2018 Yamaha YZ250F uses the KYB Air Oil Separate (AOS) forks equipped with high rigidity outer tubes for improved rider feedback.

The compression and rebound factory settings are also revised for 2018 and the fork oil capacity has been set to deliver enhanced rideability and on-track experience.

With the 2018 Yamaha YZ250F featuring a strong engine, chassis and suspension package for 2018, the model also uses a 270mm front disc brake for enhanced stopping power.

The large diameter 270mm front disc brake, combined with a heat treated 245mm rear disc, offers high levels of stopping power with accurate feel and precise control.

For 2018, keeping in line with the remainder of the new Yamaha motocross range, the YZ250F receives new graphics and blue rims to give the bike that factory look and feel.
