At the heart of the 2019 Mash TT 40 classic motorcycle, Mash relies on a 400 cc (24.4 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27.6 HP (20.1 kW) at 7,000 rpm while maximum torque reaches 29.8 Nm (22 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 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 TT 40 measures 151 kg (333 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.47 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
