Honda ST 125 Dax

From a press release issued by Honda:

Honda’s pocketful of mini motorcycles strike 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.

In 23YM a new bike joined the fold. The ST125 Dax fully owned the genuine authenticity of the 1969 original* but brought thoroughly 21st century performance from chassis, engine and ergonomics. The most recent version of the Dax was produced from 1995 to 2003 for the Japanese market; the more recent European success of its siblings hastened its return, and its mischievous charm and easy-going riding proposition bless the ST125 Dax with an extra layer of desirability.

Of course, nostalgia plays a part in the Dax’s appeal to riders now in middle age – riders who may have owned one in their youth and are pleased to see it again. Equally, ‘retro’ is important to younger owners; that’s real retro, not faux. A certain style sets some machines apart and the Dax has just that in abundance thanks to the form of its iconic T-shaped frame. Which is also how the bike got its name: extending from under the seat to the handlebars, and sitting atop the small 12-inch wheels, the look is reminiscent of the universally adored Dachshund, or Sausage Dog, to give it its everyday English name…

For 25YM, the Dax gained EURO5+ compliance to futureproof the icon, which rolls in to 26YM basically unchanged other than a revised new paint line up. This small bike carried on as before, which means it’s unique, easy, usable and great fun. Just as it has always been.

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. EURO5+ compliance was achieved for 25YM.

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. Accessories available include a clock and gear indicator display, rear carrier, side bag support, immobiliser alarm, USB socket and heated grips.

The 26YM Dax will be available in the following colour options:
- Pearl Horizon White
- Candy Energy Orange
- Pearl Shining Black

Key Features
Styling & Equipment
- Chrome high-set handlebars and upswept exhaust muffler are Dax signature pieces
- Full LED lighting and LCD instrument display
- Chrome passenger grabrail

While the ST125 Dax is small, its proportions provide enough room to be comfortable for two adults to ride.

The styling really is the frame; everything is attached to, or held within it, giving the Dax its unmistakeable retro look. As do all the other parts; the thick dual seat – seat height is just 775mm – chrome high-set handlebars and the 1970’s dirt bike-inspired upswept muffler with drilled, slotted and chromed heat shield.

The frame’s mid-section wears a black stripe with ‘Dax’ picked out in quirky font, right next to the classic Honda Wing logo that marks its special heritage. A unique finishing touch comes in the form of a cartoon image of a Dachshund.

A chromed mudguard leads and sits below the evocative, circular headlight. To add extra charm to the light, signature round LEDs are used and the front indicators/position lights sit snugly in between low and high beams. The compact instrument display is a round, negative LCD while the rear taillight and indicators take their cues from the headlight and are also LED.

There’s a neat chrome grabrail for the passenger to hold while a cover seals the drive chain away from weather and loose clothing.

Chassis
- T-shaped pressed steel frame integral to handling and looks
- 31mm USD forks, twin rear shocks and 12-inch wheels provide a smooth ride
- Hydraulic disc braking front and rear with ABS

The iconic T-shaped frame design houses the fuel tank, is authentic in aesthetic detail and constructed in pressed-steel with modern engineering know-how. Rake and trail are set at 24.9°/84mm with wheelbase of 1200mm. Wet weight is just 107kg.

31mm USD forks provide supple suspension response and, combined with the wide upswept handlebar, easy steering. Twin rear shocks are tuned for smooth compliance, even with a pillion. Blacked-out 12-inch rims (from the super-cool MSX125 Grom) wear fat, balloon-like tyres; a 120mm wide front and 130mm rear. They add sure-footed grip allied to nimble agility.

Single-channel ABS manages braking force. Hydraulic front and rear calipers grip 220/190mm diameter discs respectively.

Engine
- 124cc, air-cooled SOHC two-valve design produces 6.9kW and 10.8Nm
- Stress-free centrifugal clutch and four-speed gearbox

Drawn from the Super Cub C125 – so flexible, efficient and durable – the 124cc air-cooled engine features a SOHC two-valve cylinder head, with relatively long stroke and high compression; bore is set at 50mm, stroke at 63.1mm with compression ratio of 10.0:1. Peak power of 6.9kW arrives @ 7,000rpm, with peak torque of 10.8Nm @ 5,000rpm.

The engine’s strong performance means that even two-up a 90km/h cruising speed is achievable, with smart acceleration from low speed – just what’s needed for lively around-town amusement.
On the left-hand side of the bike the distinctive oval air box, filter and connecting tube ensure smooth, efficient airflow through the clean side, delivering crisp throttle response and driveability. The upswept muffler and heat shield is evocative of that golden motorcycling era of the ‘70s. An uprated catalyser, new ECU settings and addition of an OBD2-2 sensor ensured EURO5+ compliance was achieved for 25YM.

In keeping with the laid-back, easy to ride feel the gearbox is a 4-speed unit (with neutral at the bottom) operated via centrifugal clutch, without the need for a clutch lever. At standstill the rider simply selects the gear required with the left-hand foot lever and, as the throttle is opened, the clutch operates automatically and does so through each ratio change, up or down.

Various low-friction technologies, like an offset cylinder and roller-rocker arms in the head, ensure impressive fuel economy of 66.7km/l (WMTC mode). This gives the Dax a range of approx. 250km from the 3.8L fuel tank.

Accessories
A comprehensive range of Genuine Honda Accessories is available for the Dax. To boost everyday useability, a rear chrome luggage rack is available alongside a deep, left-hand side canvas pannier completed with an included waterproof black fabric inner bag.

For added peace of mind in all weather, heated grips and a USB socket to keep personal devices charged are available.
