Built around Dafra's sport motorcycle platform, the 2018 Dafra Riva 150 pairs a 154.4 cc (9.4 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 12.1 HP (8.8 kW) at 8,250 rpm while maximum torque reaches 10.9 Nm (8 lb-ft) at 6,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 78.4 HP per liter and a 1,650 rpm working window between peak torque (6,600 rpm) and peak power (8,250 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 Riva 150 measures 125 kg (276 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.33 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 13.3-liter (3.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
