Description

Unleash real performance from your 2025+ Yamaha MT-07 with a TST WORX ECU Tune developed specifically for full system exhausts. Engineered in-house and tested across multiple exhaust setups, this ECU flash tune delivers gains where it counts the most. With up to 9% more peak power and over 13% increase in the top end before redline, you'll feel the difference with every twist of the throttle. Expect stronger torque throughout the rev range, more aggressive throttle response in Power Mode 1, and a 400 RPM bump in the rev limiter, enabling you to push your MT-07 harder. With optimized fuel maps, advanced ignition timing, and smart ECU tweaks, like disabling the top speed limiter, decel fuel cut, and more, this tune transforms your ride while maintaining safe and reliable engine operation. Just pick your exhaust from the dropdown, send us your ECU, and experience the difference.

AFTER TUNE: Please be aware that a temporary Check Engine Light will appear and the Mode button will be temporarily disabled after reinstalling your flashed ECU. These issues will clear after two or three ride cycles and the dash will return to normal.
