Daytona 955i

1999 Triumph Daytona 955i Technical Analysis & Specification Breakdown

At the heart of the 1999 Triumph Daytona 955i sport motorcycle, Triumph features a 956 cc (58.3 cu in) liquid-cooled in-line three, four-stroke configuration. In factory specification, peak output is rated at 128 HP (93.4 kW) at 9,900 rpm while maximum torque reaches 100 Nm (73.8 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 133.9 HP per liter and a 2,400 rpm working window between peak torque (7,500 rpm) and peak power (9,900 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the Daytona 955i measures 224 kg (494 lbs) wet (curb), translating to a power-to-weight ratio of 0.57 HP/kg (1.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.9 L/100 km provides an estimated theoretical range of roughly 305 km (190 miles) between fill-ups, while factory top speed is listed at 253 km/h (157 mph).
