At the heart of the 2005 Gilera Nexus 500 scooter motorcycle, Gilera features a 460 cc (28.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 40.1 HP (29.3 kW) at 7,500 rpm while maximum torque reaches 43 Nm (31.7 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 87.2 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 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 Nexus 500 measures 216 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.39 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,515 mm (59.6 in) wheelbase engineered for balanced agility and highway composure. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
