1998 Aprilia Moto 6.5 Technical Analysis & Specification Breakdown

Built around Aprilia's allround motorcycle platform, the 1998 Aprilia Moto 6.5 relies on a 649 cc (39.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 42 HP (30.7 kW) at 6,250 rpm while maximum torque reaches 51 Nm (37.6 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 64.7 HP per liter and a 1,750 rpm working window between peak torque (4,500 rpm) and peak power (6,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Moto 6.5 measures 150 kg (331 lbs) dry, translating to a power-to-weight ratio of 0.28 HP/kg (3.57 kg per horsepower). 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.
