Technical Overview
2010 Dafier Roma 50 Technical Analysis & Specification Breakdown
Built around Dafier's scooter motorcycle platform, the 2010 Dafier Roma 50 pairs a 49.9 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.2 HP (2.4 kW) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox. Internal engine geometry specifies a bore and stroke of 39.0 x 41.5 mm (1.5 x 1.6 inches) with a 7.0:1 compression ratio.
On the scales, the Roma 50 measures 78 kg (172 lbs) dry. Rider ergonomics and chassis geometry center around a 1,210 mm (47.6 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 225 km (140 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
