Engine Displacement: 155 cc
The ZT155-U1 is powered by a 155 cc single-cylinder, liquid-cooled, 4-valve SOHC engine. It features a remarkably high compression ratio of 12.5:1, which is key to its high power output. The engine also utilizes an all-aluminum cylinder (without a liner) for superior heat dissipation, ensuring consistent performance during long climbs in the Nepalese hills.
Max Power: 19.03 PS @ 9250 rpm
Producing 19.03 PS, this bike holds one of the highest power figures in the 150cc category in Nepal. It offers two distinct riding modes: Eco (E) and Sport (S). The intelligent ECU is programmed to automatically switch to Sport mode if the engine revs pass a certain threshold, ensuring the rider has immediate power when needed for overtaking.
Max Torque: 16 Nm @ 7500 rpm
With 16 Nm of torque, the ZT155-U1 provides excellent mid-range pull. This torque is managed by a Bosch Fuel Injection system that includes an Air Temperature Sensor (ATS), which adjusts the fuel-air mixture in real-time based on altitude—a critical feature for riding in Nepal's varying elevations.
