Three ride modes, like the FJ- and FZ-09, are designated Standard, A, and B. There is no actual change in the fueling, Yamaha explained, the mode simply changes how quickly the throttle plates open. On the FZ-10 Standard is the softest, with A as the medium setting, and B the most aggressive. I tried all three and preferred Standard—considering how much power is on tap, there’s simply no reason to rush into it with super snappy response, but it’s there if that’s what you like. Beyond the power, the FZ-10’s engine is just so buttery smooth. It purrs along in the lower third of the revs, snarls in the middle, howls up top, and does all of it on command. It will be as calm or as rambunctious as you like.
