Main features of the 2020 model "YZ250FX"

1) Newly designed engine supporting high combat power in enduro

The new aluminum casting piston has been adopted to achieve improved performance at high speeds. By adding a unique mechanical processing such as taking a deep valve recess (recess at the top of the piston), it stabilizes the compression ratio and contributes to excellent power characteristics.

In addition, the optimum design of the intake side cam profile (change of the working angle, enlargement of the valve lift) is carried out in order to obtain the excellent inhalation efficiency, and a new cam chain guide and tensioner of the specification, and a light-weight design of the transmission and the shift Cam are adopted.

2) New frame that achieves flexible stiffness balance

In order to improve gap travelability, the bilateral beam frame base is shared with YZ250F for motocross. Furthermore, the rigidity of the longitudinal, lateral, and torsional rigidity is increased by about 15% on average by giving exclusive settings for enduro such as stiffening of the engine suspension main bracket (adding stiffener of 6 mm thickness on the front side) and optimization of tension pipe arrangement. Optimize the rigidity balance to the race specification. It contributes to a more light handling and flexible running, calmness and stability.

3) New specification front and rear suspension


190620_24-680x470

The front and rear suspension is based on YZ250F for motocross, and the setting matched to the enduro race was given. The front is an inverted suspension (gas-liquid separation type), which optimizes the rigidity balance of the outer tube and improves the feeling of grounding. The rear adjusts the stroke length of the link type monochromus suspension and the drooping angle of the rear arm, etc. to achieve both good gap absorbability and improvement of operability.

4) Lightweight, compact and easy to restart self-starter

The self-starter uses a lightweight lithium-ion battery for the power supply. In addition, the starter motor is designed to be lightweight and compact, and is placed close to the center of the vehicle, helping to optimize the vehicle's weight balance.

5) Power tuner with engine setting available on smartphone

The power tuners for engine setting change the device from a conventional controller to a smartphone with a dedicated application installed.The setting operation is performed by wireless communication between the device and the vehicle-mounted CCU.The 2-pattern engine map can be saved on the vehicle body, and the mode switch placed on the left handlebar allows you to switch to suit the situation even during the race.

*The smartphone is not included with the main body of the vehicle

6) large-capacity clutch focusing on durability improvement

It uses eight friction plates, which are excellent in heat resistance and durability. We coped with a heavy load situation such as frequent shift changes and half clutch operation performed during a long race. The surface of the plate is knurled (finely dented) to improve friction and spring load, which contributes to a good operation feeling.
