Built around Yamaha's naked motorcycle platform, the 1972 Yamaha CS5 utilizes a 195 cc (11.9 cu in) twin, two-stroke layout. In factory specification, peak output is rated at 22 HP (16.1 kW) at 7,500 rpm while maximum torque reaches 21.3 Nm (15.7 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 112.8 HP per liter and a 500 rpm working window between peak torque (7,000 rpm) and peak power (7,500 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 CS5 measures 117 kg (258 lbs) dry, translating to a power-to-weight ratio of 0.19 HP/kg (5.32 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,245 mm (49 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank paired with a rated consumption of 2.85 L/100 km provides an estimated theoretical range of roughly 316 km (196 miles) between fill-ups, while factory top speed is listed at 135 km/h (84 mph).
