Description
The 2020+ Yamaha YZF-R1’s crossplane engine has a sound all its own, and with a full-system aftermarket exhaust, there’s still more performance to unlock. The TST WORX Performance ECU Tune is developed to take that setup even further, with optimized ECU parameters that result is substantial power gains throughout the rev range, increasing peak power by 16% compared to stock and around 11% compared to the aftermarket exhaust alone. It also delivers massive gains near the red line, smashing a 33% increase compared to the stock setup and up to 20% compared to a bike with just an aftermarket exhaust and the stock tune. You’ve already got the sound and the exhaust, now give your Yamaha R1 the power to match!
AFTER TUNE: Please be aware that a temporary Check Engine Light may appear on the dash, during which the Mode selction will not be functional. This is completely normal, and these issues will clear after two or three ride cycles.
