ST DAX SERIES: Quirky or what!

- WORDS: Steve Cooper

Not that long ago folk who were into small-wheeled, semi-children’s, not-safe-on-the-road motorised two-wheelers were looked upon as being certifiabl­y mad. But there’s plenty of fun to be had at the small end of the biking spectrum. That’s where Honda’s DAX comes in. Steve Cooper breaks down what you need to know about the Monkey bike’s less desirable brother.

Only the truly loopy really ‘got’ the lure and appeal of such strange and perverse devices. These were the true devotees who willingly would pay bonkers money for a machine with no suspension and the handling characteri­stics of a chinchilla on meth amphetamin­e! Most of us Brits really couldn’t grasp why you’d want to ride any motorcycle with tyre sizes less than 16 inches, let alone 10-inch ones, and fewer still could get their heads around paying serious dosh for what looked like a commuter bike that had shrunk in a hot and aggressive wash.

Things began to change back in the late noughties when we went into a recession and enthusiast­s were still keen to restore something, anything in fact, just to stay ‘on the tools’. Folk began hoovering up projects and spares for the Honda Chaly, Suzuki trail Hoppers, Kawasaki KVs and the like. Even this numpty got caught up in the giddy spiral of Japanese mini-bikes and restored a Yamaha Chappy. The seeds had been sown and gradually these quirky little motorcycle­s gained grudging acceptance. Things took a dramatic turn a couple of years ago when John Lennon’s Z50A Honda was sold at auction for a jaw-dropping, poke-mein-the-eye-with-a-stick-please, theymust-be-raving-mad, £57,000. Yes, obviously The Beatles’ provenance had a lot to do with it, but suddenly ‘monkey bikes’ had come of age!

Our subject matter this month represents the higher middle ground of pseudo-simian motorcycli­ng; unquestion­ably more prestigiou­s than the later Chaly’s, but significan­tly more affordable than almost any of the iconic Z series. The bike in camera is a mid-1970s Honda DAX, also marketed as the ST70, Trail 70 or CT70, depending upon which part of the world you were buying it. Designed in the late 1960s and launched globally in 1969, the range offered 50, 70 and 90cc variants depending upon market preference­s, targeted age groups and local licencing laws. Rather than attempting to reinvent the wheel (something Honda would later actually do with the Comstar hoops) the firm utilised exhausting power plants from its series-C commuter range with two transmissi­ons, again dependent upon market. Your DAX (the Japanese market model designatio­n) could either utilise the convention­al, proven, tried and tested, semi-automatic, crunch 3-speed or a 4-speed manual gearbox with convention­al clutch.

Even if the DAX/ST vaguely aped (sic) the original monkey bikes in general profile there was a raft of important changes applied that, in reality, totally distanced the new model from its predecesso­rs. Most obvious was the T-bone or pressedste­el frame that ousted the earlier basic tubular constructi­on. Next up was the suspension – it actually got something that worked. Rear shocks and vaguely compliant forks took the DAX/ST variants several leagues ahead of the previous offerings, which meant rider comfort was no longer entirely dependent upon bouncy balloon tyres. A semi-sensible dual seat and pillion footrests added a touch of convention­ality to the bike, even if it was only the maddest who actually used one two-up!

Despite being what many would perceive as something of a novelty machine, the ST range ran from 1969 through to 1982 for certain models, with the ST50 coming back on line from 1995 to 2000 for some markets. One of its key appeals has to be the way Honda chose to paint the bike. Earliest examples are generally in candy colours and for once not just red or blue. Both the gold and burnt orange variants really stand out along with the ivory white version here. Subsequent colour schemes attempted, and largely managed, to keep up with the times, employing flat silver, bright blues and vivid greens counterpoi­nted by lurid decals… no one could ever accuse the model range of being dull!

So what are they like to ride, you ask? Simply, totally and utterly unlike anything else you have ever experience­d. You don’t just sit with your feet flat on the deck, your legs are bent at right angle from the hips. Although there’s only sub 10bhp to hand, the lack of mass and proximity to the ground more than makes up for absence of brute power. Things seem to happen much faster than you’d expect and, with a minimalist wheelbase, you find yourself negotiatin­g bends much faster than you’d expect or possibly even like. The first few rides on any monkey bike can be a heady mixture of overt surprise dosed with manic hilarity. And if riding a DAX doesn’t have you smiling and giggling at the absurdity of it all, you probably need to have a word with yourself!

 ??  ?? There’s a centrifuga­l oil-filter in the middle of the clutch which needs occasional cleaning. If ignored the motor’s lifespan can be significan­tly reduced.
OEM is always best, but there are lots of pattern and go-faster options out there.
Split covers often result in rotted out seat pans, so check underneath for terminal corrosion.
Laid-up examples can suffer from air-filter foam crumbling and falling inside the carb. Best to check before firing up!
Poor maintenanc­e/servicing can lead to flailing cam-chains. If the motor sounds thrashy, find a better example or be prepared for a rebuild.
Check the oil on any potential purchase. If it’s like treacle or full of shiny particles, walk away! 1. ENGINE 2. EXHAUSTS 3. SEAT PAN 4. CARBURETTO­R AND AIR-FILTER 5. CAM-CHAINS 6. OIL
