Development of Monpal ML200 4-Wheel Scooter

Article of Honda R&D Technical Review Vol.18 No.2


The Monpal ML200 4-wheel scooter has been developed based on the “Smart Package” concept.
Increased static and dynamic stability and greater user comfort were realized by adopting A-arm independent front and floating axle type rear suspensions and by reducing the center of gravity by locating the main parts lower down.
A metal base plate was adopted for the motor controller, while the use of a 3D map system identification speed control and a Honda-manufactured brushless motor with an integrated transmission improved efficiency and reduced drive resistance.
The scooter’s overall electrical consumption was improved by 9% over that of the current Monpal ML100 model, and a running distance of 34.3 km on a single battery charge was achieved.
Moreover, the arrangement of the lights, based on Honda ASV-3 LONG technology, has enhanced visibility.
