Wi-Fi tuning comes to 2021 Suzukis

Looks like bold new graphics and the new Wi-Fi tuning system is all that’s new on the 2021 Suzuki RM-Z range. The tuner is also backwards-compatible to the 2020 450 and 250 models and 2019 RM-Z250 too.

Included with the 2021 RM-Z250 and RM-Z450 is Suzuki’s MX-Tuner 2.0 that provides the ability to easily adjust the fuel injection and ignition system settings for optional race performance.

The 450

Using a smartphone application that wirelessly connects to the MX-Tuner’s compact transceiver, fuel delivery and ignition timing can be quickly changed. The MX-Tuner application can pre-program personalized settings into the ECM that can be activated by plugging in one of the supplied fuel couplers.
Racers and tuners can easily change settings to match performance-related updates. The application can save a number of settings for different tracks or weather conditions, plus settings can be exchanged with other racers.
Real-time engine data and run-time information are accessible to help you stay on top of bike maintenance.
