Built around Tomos's sport motorcycle platform, the 2005 Tomos Streetmate relies on a 49 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 3.1 HP (2.2 kW) at 5,700 rpm while maximum torque reaches 4.7 Nm (3.5 lb-ft) at 3,800 rpm. Internal engine geometry specifies a 10.0:1 compression ratio.
On the scales, the Streetmate measures 64.9 kg (143 lbs) dry. Rider ergonomics and chassis geometry center around a 787 mm (31 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 3.48-liter (0.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
