ST125 DAX – 23YM

Honda’s pocketful of mini motorcycles has struck a chord with young and old riders alike. The re-imagined Monkey 125 tugs at heart strings that remember the golden 1970s while  providing thoroughly modern, compact and funky urban transport for riders of any age. The MSX125 Grom serves up left-field, customisable style for ‘Generation Y’ but also as perfect paddock transport in the worlds of car and bike racing.

Model Overview

As it should, the Dax keeps it simple. A steel frame provides strength and houses the fuel tank while 31mm USD forks, twin rear shocks and 12-inch wheels with chunky tyres provide light steering and good suspension performance. Braking is via hydraulic discs front and rear with ABS control.


Robust and fuel efficient, the 124cc SOHC two-valve engine’s power is linear in delivery with smooth torque. A centrifugal clutch manages shifting between the four ratios so there’s no need for a handlebar-mounted clutch lever. It offers twist-and-go simplicity with the added entertainment of changes via a traditional left-foot gear lever.


All lighting is LED and a circular LCD display shows exactly what the rider needs to know. The pillion gets a chromed grab rail, too.
