Description
The 2025+ Kawasaki Z900 delivers an incredible riding experience straight from the factory, but there's plenty of untapped performance hiding beneath the surface. That's where our TST WORX engineers step in. Using our in-house dyno, we've developed a custom ECU bench flash that optimizes engine performance and delivers substantial power gains throughout the RPM range. How substantial? We're talking over a 34% increase in top-end power, more than 8% additional power in the midrange, and a 4% boost in peak horsepower compared to a Z900 equipped with an aftermarket exhaust and stock ECU tune. The result is a more responsive, powerful machine that delivers the performance you want, whether you're carving through corners or opening up the throttle on the straights. Unleash the true potential of your Kawasaki Z900 with a TST WORX Performance ECU Tune and experience the difference for yourself!
AFTER TUNE: Please be aware that the Check Engine Light will be on and the Riding Mode and KTRC will flash after reinstalling the ECU. All of these will clear after one or two rides of at least 35-45 MPH.
