2011 Zest Z125T-1 Technical Analysis & Specification Breakdown

Engineered by Zest for the scooter motorcycle segment, the 2011 Zest Z125T-1 pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 7.8 HP (5.7 kW) at 7,500 rpm while maximum torque reaches 8 Nm (5.9 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 62.4 HP per liter and a 1,500 rpm working window between peak torque (6,000 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 Z125T-1 measures 89 kg (196 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,075 mm (42.3 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 260 km (162 miles) between fill-ups, while factory top speed is listed at 85 km/h (53 mph).
