Speed Twin 1200 Specifications

The Triumph Speed Twin 1200 runs a 1,200cc liquid-cooled parallel-twin with an 8-valve SOHC head and a 270° firing order - the configuration that gives every big Bonneville-family twin its offbeat, almost V-twin exhaust note. Output is 103.5 bhp (105 PS) at 7,750 rpm and 112 Nm at 4,250 rpm. That torque figure is the headline: it peaks barely above idle-plus-fast-cruise revs, which is why the bike feels so relaxed in real use. A six-speed gearbox and a wet multiplate slip-and-assist clutch handle the transmission, and the RS, Cafe Racer Edition and TFC add Triumph Shift Assist, an up-and-down quickshifter.

The chassis is built around 43mm Marzocchi upside-down forks with 120mm of travel, paired with twin Marzocchi rear shocks that use external reservoirs and adjustable preload, giving 116mm of wheel travel. Step up to the RS and both ends become fully adjustable, with Öhlins units replacing the Marzocchi shocks at the rear. Dimensions are 2,070mm long, 792mm wide and 1,140mm tall on a 1,413mm wheelbase, with a 805mm seat height on the standard bike and 810mm on the RS.

Braking is handled by twin 320mm front discs with four-piston radial calipers - Brembo Stylema M4.30 units on the RS and above - and a single 220mm rear disc with a two-piston caliper. A new IMU underpins lean-sensitive traction control and cornering ABS on every variant.

Wheels are 17-inch front and rear, running 120/70 R17 and 160/60 R17 tubeless tyres: Metzeler Sportec M9RR on the standard bike, stickier Metzeler Racetec RR K3 rubber on the RS. Riding modes number two on the standard variant, Rain and Road, with the RS gaining a third Sport mode. The round instrument pod combines an LCD and TFT panel with Bluetooth, turn-by-turn navigation and a USB-C socket, and lighting is full LED throughout.
