UPGRADE 3.15

The KX 250 F and KX 450 F series represent a well-established reference in the motocross and enduro racing world.

With the introduction of BENCH mode, direct access to the Keihin 21175-11XX ECU is now available without opening the control unit. OBD and BOOT connections are already supported, now completing all operational possibilities on the ECU.

In the workshop, this means being able to work on maps with a fast and non-invasive workflow, adapting engine behavior to track requirements.
