2001 MZ Mastiff Technical Analysis & Specification Breakdown

At the heart of the 2001 MZ Mastiff enduro - offroad motorcycle, MZ utilizes a 659 cc (40.2 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 50 HP (36.5 kW) at 6,500 rpm while maximum torque reaches 57 Nm (42 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 75.9 HP per liter and a 1,250 rpm working window between peak torque (5,250 rpm) and peak power (6,500 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 Mastiff measures 175 kg (386 lbs) dry, translating to a power-to-weight ratio of 0.29 HP/kg (3.5 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 165 km/h (103 mph).
