1998 MuZ Mastiff Technical Analysis & Specification Breakdown

Engineered by MuZ for the enduro - offroad motorcycle segment, the 1998 MuZ Mastiff relies on a 660 cc (40.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 50 HP (36.5 kW) while maximum torque reaches 57 Nm (42 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 75.8 HP per liter, 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 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.31 HP/kg (3.2 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.
