FEATURES

Yamaha Off Road Motorcycles YZ250F Cyprus

High performance cylinder head

The YZ250F’s reverse cylinder head is all-new for 2017, and now features higher lift cam profiles as well as larger diameter intake valves and stronger valve springs. Fitted with a new big bore front exhaust, this advanced power-boosting head gives you stronger mid to high rpm pulling power for a real advantage from the drop of the gate.

Increased intake efficiency

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 2017 model features a shorter intake funnel. Combined with a new throttle joint that gives a 5% larger opening into the raised intake port, this highly efficient design gives you more power.

Refined aluminium beam frame

The YZ250F’s aluminium beam frame has been refined for 2017, and the area behind the swingarm pivot point is 12mm wider, giving higher torsional rigidty for increased handling stability. The new steel engine mounting brackets enhance rideability, and repositioned 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 for the new model year they are equipped with higher rigidity outer tubes that give improved rider feedback. Compression and rebound factory settings are also revised, and fork oil capacity is amended to deliver enhanced rideability.

Smoother transmission

To handle the increased power, the transmission has been redesigned with wider teeth and modified dogs. Together with the new shift cam and improved clutch activation, these upgrades give smoother, quicker and more positive shifting. The new ECU features revised ignition and fuelling maps, as well as a higher rev limit for improved 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 new 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.
