Technical Overview
1963 Montesa Impala 175 Sport Technical Analysis & Specification Breakdown
Engineered by Montesa for the sport touring motorcycle segment, the 1963 Montesa Impala 175 Sport relies on a 175 cc (10.7 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 18 HP (13.1 kW) at 7,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 102.9 HP per liter, 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 Impala 175 Sport measures 100 kg (220 lbs) wet (curb), translating to a power-to-weight ratio of 0.18 HP/kg (5.56 kg per horsepower). The 9-liter (2.4 US gal) fuel tank paired with a rated consumption of 5 L/100 km provides an estimated theoretical range of roughly 180 km (112 miles) between fill-ups, while factory top speed is listed at 131 km/h (81 mph).
