Positioned in Triumph's sport motorcycle lineup, the 2005 Triumph Daytona 955i pairs a 955 cc (58.3 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 149 HP (108.8 kW) at 10,700 rpm while maximum torque reaches 100 Nm (73.8 lb-ft) at 8,200 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 156 HP per liter and a 2,500 rpm working window between peak torque (8,200 rpm) and peak power (10,700 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Daytona 955i measures 191 kg (421 lbs) dry, translating to a power-to-weight ratio of 0.78 HP/kg (1.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,426 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 16.6-liter (4.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
