Triumph's TFC concept roadster promises to be the last word on cruisers when it starts limited production later in 2019. The centerpiece of any motorcycle is the engine, and the Rocket TFC packs the largest production powerplant of any bike in the world — a massive 2,500cc three-cylinder, bigger than the motor in some small cars. The details of the Rocket TFC look just as impressive as the engine, with Brembo brakes, USD forks, a single-sided swingarm, and stylish touches like hand-painted gold accents. Familiar twin headlights and an interchangeable solo or duo seat make the bike perfect for a hair-raising ride or a more relaxed cruise with a friend — on one of the most original bikes made. The Rocket TFC will be revealed fully in May.
