High performance cylinder head
The YZ250F has a reverse cylinder head, and features high lift cam profiles as well as large diameter intake valves and strong valve springs. Fitted with a big bore front exhaust, this advanced power-boosting head gives you strong mid to high rpm pulling power for a real advantage from the drop of the gate.
With its high revving design, the YZ250F sucks in tens of thousands of litres of fresh air in a typical moto, and in order to reduce pumping losses, the model features a short intake funnel. Combined with a throttle joint that gives a 5% larger opening into the raised intake port, this highly efficient design gives you more power.
Aluminium beam frame
The YZ250F has an refined aluminium beam frame with a wider area behind the swingarm pivot point, giving higher torsional rigidty for increased handling stability. The steel engine mounting brackets enhance rideability, and the footrests give a roomier riding position with a lower centre of gravity.
High rigidity front forks
The YZ250F’s Air Oil separate (AOS) front forks are regarded as being amongst the best in the class, and they are equipped with high rigidity outer tubes that give great rider feedback. The compression and rebound factory settings are revised compared with the previous model update, and fork oil capacity is set to deliver enhanced rideability.
To handle the power, the transmission has wide teeth and modified dogs. Together with the shift cam and clutch activation, they give smooth, quick and positive shifting. The ECU features such ignition and fuelling map settings, as well as a high rev limit for superb over-rev feeling.
270mm front disc brake
Braking power is just as important as engine power when it comes to reducing lap times, and the YZ250F is equipped with a large diameter 270mm front disc brake and a heat treated 245mm rear disc. This highly efficient system delivers high levels of stopping power with accurate feel and precise control, enabling you to brake harder and later.
