Positioned in Triumph's motorcycle lineup, the 2026 Triumph Trident 660 pairs a 660 cc engine architecture with road-focused gearing. In factory specification, maximum torque reaches 68 Nm, transferring power to the rear wheel through a 6 speed gearbox and x-ring chain final drive. Internal engine geometry specifies a 12:1 compression ratio.
On the scales, the Trident 660 measures 195 kg (430 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,402 mm (55.2 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 4.9 L/100 km provides an estimated theoretical range of roughly 286 km (178 miles) between fill-ups.
