The Monkey is equipped with an engine designed to ride and have fun on; 124cc, SOHC with 50mm bore, 63.1mm stroke and compression ratio of 10.0:1. It produces peak power of 6.9kW @ 6,750rpm with peak torque of 10.7Nm @ 5,500rpm.
A correcting plate manages the path of fresh air drawn in and feeds an intake duct inlet and connecting tube designed to smooth airflow. The shape of the airbox also promotes smooth airflow, smooth torque output and flexible drivability. EURO5+ compliance has been applied via revised ECU settings, updated catalyser and additional O2 sensor.
The 5-speed gearbox spreads its ratios apart for longer journey ease and provides a more relaxed cruising ability. Top speed is 91km/h. Manual clutch operation imparts a full-sized motorcycle experience while 12-inch wheels deliver agile around-town response. Naturally, the Monkey’s small stature and assured low-speed balance allow it an easy passage through jammed traffic.
It’s also an economical engine, returning 1.5 litres/100km (WMTC mode) by using low-friction technologies, such as an offset cylinder and roller-rocker arm for the valve gear. Sophisticated PGM-FI guarantees highly efficient combustion.
