HONDA CRF450 R/L ECU Remap – KEIHIN STAGE 1

More power and torque for your Honda CRF450 R/L. The tuning software has been carefully developed and specifically calibrated for the 450 engine.

For the 2025/2026 CRF450R models, we can also create RWE (Works Edition) software. For this setup, an aftermarket exhaust system (Akrapovic, Yoshimura, etc.) and a TwinAir air filter should be installed.

Option 1: RWE US Version

Option 2: RWE EU Version

Optimized parameters include:

1. Ignition
2. Fueling
3. Rev limiter (according to customer requirements)
4. Lifetime up-to-date software – we are constantly working to improve our software, and our customers always receive the latest tuning software updates free of charge.

All functions of the map switch remain unchanged.

After the optimization, we recommend using SHELL V-Power 100 octane fuel or racing fuel such as VP Racing Fuel, etc.

For this offer, the ECU must be sent to us for programming.
