Technical Overview
1975 Puch MC 125 Technical Analysis & Specification Breakdown
Positioned in Puch's cross - motocross motorcycle lineup, the 1975 Puch MC 125 pairs a 125 cc (7.6 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 19 HP (13.9 kW) at 8,700 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 152 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the MC 125 measures 103 kg (227 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.42 kg per horsepower). Rider ergonomics and chassis geometry center around a 840 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,355 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry.
