Engineered by WT Motors for the scooter motorcycle segment, the 2021 WT Motors Miami Grandvolum 250 features a 244 cc (14.9 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 7,000 rpm while maximum torque reaches 19 Nm (14 lb-ft) at 3,250 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 60.7 HP per liter and a 3,750 rpm working window between peak torque (3,250 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 Miami Grandvolum 250 measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.78 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 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
