Built around Triumph's custom - cruiser motorcycle platform, the 2020 Triumph Rocket 3 TFC relies on a 2458 cc (150 cu in) liquid-cooled in-line three, four-stroke powerplant. In factory specification, peak output is rated at 182 HP (132.8 kW) at 7,000 rpm while maximum torque reaches 225 Nm (166 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 74 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Rocket 3 TFC measures 290 kg (639 lbs) dry, translating to a power-to-weight ratio of 0.63 HP/kg (1.59 kg per horsepower). Rider ergonomics and chassis geometry center around a 773 mm (30.4 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 8.11 L/100 km provides an estimated theoretical range of roughly 222 km (138 miles) between fill-ups.
