After the injection problems that let the TT600 down, the Triumph Daytona 600/650's Keihin system’s brand new. And it’s much better. There’s still a bit of a flat spot in the midrange, but it’s not dire, and the bulk of the Triumph Daytona 600/650's power is still very much up top but, in all, the power band’s wide, accessible for most riders and comes with smooth delivery.
