This is a small and economical step-through motorcycle. Not quite a scooter and not quite a motorcycle, it is somewhere between the two.
The C90 is powered by a 90cc engine that's mated to a semi-automatic gearbox. There are 3 gears, which are engaged using a centrifugal clutch. This arrangement means there is no need for a clutch lever.
The slightly unusual gear shifter configuration can be counter-intuitive to seasoned motorcyclists. Shifting up requires you to push down on the gear shift, with another pedal behind your foot to shift down.
