Engineered by Malaguti for the scooter motorcycle segment, the 2009 Malaguti SpiderMax RS500 pairs a 493 cc (30.1 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 40.9 HP (29.9 kW) while maximum torque reaches 40.4 Nm (29.8 lb-ft) at 7,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 83 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the SpiderMax RS500 measures 204 kg (450 lbs) dry, translating to a power-to-weight ratio of 0.2 HP/kg (4.99 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 14.5-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
