Built around Mh's scooter motorcycle platform, the 2023 Mh Viro 350 relies on a 350 cc (21.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW) at 7,500 rpm while maximum torque reaches 28.5 Nm (21 lb-ft) at 6,500 rpm. With a specific output of 77.1 HP per liter and a 1,000 rpm working window between peak torque (6,500 rpm) and peak power (7,500 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 Viro 350 measures 163 kg (359 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (6.04 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,548 mm (60.9 in) wheelbase engineered for planted straight-line stability. The 17.4-liter (4.6 US gal) fuel tank paired with a rated consumption of 2.3 L/100 km provides an estimated theoretical range of roughly 757 km (470 miles) between fill-ups.

Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
