Built around Mash's allround motorcycle platform, the 2019 Mash Scrambler 400 utilizes a 397 cc (24.2 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 27.6 HP (20.1 kW) at 7,000 rpm while maximum torque reaches 30.6 Nm (22.6 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 69.5 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 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 Scrambler 400 measures 160 kg (353 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (5.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
