2020 Triumph Bonneville T100, Wow! Great Looking Air Cooled, Fuel Injected Bonneville! This bike has only 8,933 Miles on it!!!! They have taken one of the most famous name in motorcycling and gave it some extra 60s style. Still distinctly a Bonneville with its smooth pulling, fuel injected 900cc parallel twin. This is the "Blacked out" model. Triumph has added some visual tweaks like twin peashooter exhausts, Blacked out engine covers, black instrument surround with tach, a Triumph logo on the seat, two-tone paint, spoked wheels and fork gaiters. What a classic, Retro look!!! So, it still looks, sounds and feels like a proper motorcycle should. And it still connects you to over 50 years of heritage but is built with everything that comes with modern engineering too. Features include: Engine The iconic, air-cooled parallel twin sits proudly at the heart of the Bonneville T100. Setting the style for the entire bike. Exhaust Twin, Black, peashooter exhaust pipes give this bike extra 60s style. Wheels Classic spoke, Blacked out wheels for great looks and easy handling. Seat Different in style from the standard Bonneville, It has been given the 60s look with smooth topped seat with the Triumph logo on it. Performance From day one the Bonneville have been built to be ridden, not just to look good. Today, this 900cc parallel twin puts out a healthy amount of horsepower, and lots of torque available at low revs so you get most use out of it. The fuelling is controlled by a sophisticated management computer programed for clean emissions and a smooth, predictable throttle response. So there’s enough performance to be fun for experienced riders but not so much that will intimidate riders with fewer miles behind them. Configuration A pair of cylinders still stand upright and proud at the heart of the Bonneville T100. With a wide bore and short stroke that adds up to 900cc for high levels of efficiency and low wear, with four valves per cylinder for the best breathing and power. There are balance shafts tucked away inside the crankcase so you’ll notice very little vibration for a parallel twin and, being air cooled, there’s no radiator to spoil the view. Frame All of Triumphs extensive chassis experience and technology has gone into the Bonneville T100’s simple tubular steel construction. Providing easy, neutral steering and exceptional balance even at low speeds. Suspension Looking good while working hard isn’t easy. But the 1960s style twin shocks fitted at the back come with a chrome finish and modern damping internals. As do the traditional-looking forks. And that makes the ride of your Bonneville T100 smooth and controlled, even on bumpy roads and cornering at speed. This bike is just as clean as a new one, It has only 8,933 Miles on it!!!
