The Graves pieces really woke up the FZ-10. While we were definitely happy with the top-end increase of 16 hp (from 131 to 147 hp), there was a major boost in low-end and midrange power as well, making the Yamaha even more fun to ride. And the beauty of the Flash Tune ECU FZ-10 setup is that there’s no need to send in your ECU; the Bike Side Tune Kit allows you to tap into the ECU without removing any bodywork, download various maps with an internet connection, and make any tuning changes easily with a laptop. With your base map set, the Active Tune AFR setup then continually fine-tunes the fueling for changing ambient conditions. The Auto-Blipper Shift System was sort of a superfluous add-on, but we will say it was fun to use with its flawless upshifts and downshifts without the clutch.
