We offer advanced ECU tuning solutions for 4-stroke Kawasaki motorcycles equipped with Keihin engine control units. 

On this page, we present the binary calibration file (XDF) for Kawasaki KX250F, KX250X, KX450F, and KX450X, compatible with TunerPro software. This allows for optimizing engine performance, enhancing power and torque without compromising reliability. 

Discover more about tuning options for your model.

Also available WinOLS OLSX mappack.

Supported all motorcycles from year 2012 to year 2023.

Some of the supported bikes:

  • Kawasaki KX250F
  • Kawasaki KX250X
  • Kawasaki KX450F
  • Kawasaki KX450X

Knowledge, experience, calibration studies and bench tests are the starting point for the development of the above mentioned bin definition files (xdf).

A free tuning software combined with competitive prices (80 euro) are the milestones of our philosophy.

Through the definition files, the remapping software TunerPro identifies the engine working parameters which allow to obtain the maximum power and torque without affecting the degree of reliability.

TunerPro is a binary files editor, not able to read and write the engine control unit. To do this, you need an external tool. We don’t provide information about these tools.
