Built around Sachs's naked motorcycle platform, the 2001 Sachs Roadster 125 V2 utilizes a 124 cc (7.6 cu in) v2, four-stroke layout. In factory specification, peak output is rated at 13.6 HP (9.9 kW) at 9,500 rpm while maximum torque reaches 9.9 Nm (7.3 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 109.7 HP per liter and a 500 rpm working window between peak torque (9,000 rpm) and peak power (9,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Roadster 125 V2 measures 133 kg (293 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.78 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 1,495 mm (58.9 in) wheelbase engineered for balanced agility and highway composure. The 20-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
