At the heart of the 1993 Yamaha YZF 750 SP sport motorcycle, Yamaha relies on a 749 cc (45.7 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 125 HP (91.2 kW) at 12,000 rpm while maximum torque reaches 79.8 Nm (58.9 lb-ft) at 9,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 166.9 HP per liter and a 2,500 rpm working window between peak torque (9,500 rpm) and peak power (12,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the YZF 750 SP measures 191 kg (421 lbs) dry, translating to a power-to-weight ratio of 0.65 HP/kg (1.53 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 19-liter (5 US gal) fuel tank paired with a rated consumption of 6.25 L/100 km provides an estimated theoretical range of roughly 304 km (189 miles) between fill-ups, while factory top speed is listed at 270 km/h (168 mph).
