2001 Sachs Roadster 800 Technical Analysis & Specification Breakdown

Positioned in Sachs's naked motorcycle lineup, the 2001 Sachs Roadster 800 features a 805 cc (49.1 cu in) v2, four-stroke configuration. In factory specification, peak output is rated at 58 HP (42.3 kW) at 6,000 rpm while maximum torque reaches 71 Nm (52.4 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 72 HP per liter and a 2,000 rpm working window between peak torque (4,000 rpm) and peak power (6,000 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 Roadster 800 measures 226 kg (498 lbs) wet (curb), translating to a power-to-weight ratio of 0.26 HP/kg (3.9 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 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 175 km/h (109 mph).
