Technical Overview
2008 Super Motor New Spyder YB50QT Technical Analysis & Specification Breakdown
Engineered by Super Motor for the super motard motorcycle segment, the 2008 Super Motor New Spyder YB50QT relies on a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 4 HP (2.9 kW) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 39.0 mm (1.5 x 1.5 inches) with a 12.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 3 L/100 km provides an estimated theoretical range of roughly 267 km (166 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
