General information about the Triumph Bonneville T120 Ace
The 2019 Triumph Bonneville T120 Ace is purely a styling exercise. Underneath all the custom parts is a standard Bonneville T120 Black. That means you get the 1200cc High Torque engine, along with modern electronics ranging from ride-by-wire to a USB charging outlet. However, one could argue that the shorty fender from the Triumph accessory catalog is functional.
A 25.5° steering-head angle and 18-inch front wheel give it 4.14-inches of trail and an eager demeanor in the curves in keeping with its stoplight-racing roots. A 17-inch rear rim rounds out the rolling chassis, and of course, the look of the laced wheels accentuate the dated panache of the bike and mount a 100/90 up front and a 150/70 around back.
