KESS3 Protocols Releases
Alientech expands its coverage dedicated to the off-road racing world.
29.10.2025 — Upgrade 2.54
With this update, KESS3 allows you to work on Honda CRF 250 and 450 models from 2020 up to the latest 2025 version, equipped with Keihin 38770-MKE ECUs, offering full support designed for professional race bike tuning.
Thanks to the OBD connection, you can read and write the ECU directly through the diagnostic port — quickly, precisely, and completely safely.
A key advantage for those working in motorsport: optimise torque curve, improve throttle response, and customise power delivery according to the track and the rider’s style.
The protocol is also available for Powergate, the perfect solution for teams and riders who want to manage their own bike tuning independently, with the same level of safety guaranteed by Alientech technology.
Expand your workshop services and offer professional technical support to racers: maximum performance, reduced intervention times, and absolute reliability — even in the most extreme conditions.
