Description
We've done a lot of development work on the Yamaha MT-09 and MT-09 SP, but for the most part, we focused on improving the looks...until now. We passed our Yamaha MT-09 over to our WORX Racing Division engineer team to let them unleash their racing and tuning knowledge on the Yamaha CP3. Their engineering and tuning efforts have led our TST Race Team to multiple ASRA National Championships, and have proven that the Yamaha MT-09 can be even more fun with the right tune! By optimizing the ECU with our TST Performance Reflash, you will immediately notice more power output and better performance every time you open the throttle. Not only are peak power figures increased, but we improved horsepower and torque across the entire rev range as well as optimized the MT-09 by adjusting or disabling a wide range of parameters that aid in overall performance and operational improvement. Give your Yamaha MT-09 or MT-09 SP an extra kick of power with the TST WORX Performance Tune.
