The bike Triumph had available for us to test, the up-spec, sport-focused RS, also comes with additional ride modes, a beautiful and highly functional TFT dash, a quickshifter, top-shelf suspension and brakes, and even a special engine tune to boost top-end power. The RS is the fanciest of the three varietals that make up the 2017 Street Triple lineup, and as such it carries a $12,500 price tag. (The base Street Triple R, which has lower-level suspension and brakes, simplified electronics, a standard dash, and less power, costs $9,900.) Part of that expense went toward lowering the curb weight, which is now just 419 pounds with a full tank. Triumph must have also hired a team of jewelers to scrutinize the details because the fit, finish, and function of this machine are impressive, from the transmission action to the way the levers look and feel. It's polished to a glorious shine.
