a trip back in time! That was my first impression when I got behind the handlebars of the XT 125 X, not because of its lines, which are very much in tune with the times, but rather because of the power available, which forces you to anticipate any overtaking manoeuvre like in the good old days of our 5Occ!
Static presentation :
The 2 beasts are lined up in my garage, highlighting the differences in size and look.
The 2 machines are the result of different approaches: on the one hand, the XTX, a funnier presentation of the 125 YBR utility bike, with its 4-stroke, air-cooled, 10 hp/din engine; and on the other, the Supermotard evolution of an old enduro acquaintance: the DT 125 R. The latter features a liquid-cooled 2-stroke single with Yamaha's own exhaust valve. In this case, however, the engine has been deflated to meet car-licensing standards, and now develops just 15hp!
The XTX is much more slender and low-slung (seat height 830mm vs. 880mm on the DTX), but its KTM-esque orange highlights its more contemporary lines.
The DTX, on the other hand, relies more on Supermotard weaponry: excel rims, beefy tires and a 260mm front disc.
The instrument panels are also reminiscent of the original vocation of each bike.
On the DTX, there's a simple analog speedometer surrounded by a series of very square indicator lights, and a trip meter with scroll wheel reset. On the XTX, it's Star Wars! Thanks to a switch on the left commodo, the digital display shows the counters, a rev counter or battery charge + 2 trips, a stopwatch and the time. The operation requires a university degree, but you'll get the hang of it!
Engine! Both machines feature an electric starter. However, only the 4-stroke single has a kick starter.
Contact and choke on the carburettor for the DTX and choke on the handlebars for the XTX. And then, a little disappointment: between the noise of a big moped and the poum poum of a lawnmower, our 2 machines don't flatter the ear!
In the saddle, the first big differences become apparent... the softness of the XTX's seat and suspension contrast with the firmness of these 2 elements on its rival of the day. What's more, the XTX is lower on the ground, which is sure to please future female customers.
On the road, the XTX of the day boasts just 72km on the odometer, which goes some way to explaining its apathy when revving up, and the 30% difference in power between the 2 machines doesn't let its 4-stroke single shine!
The gearboxes (5 speeds for the XTX and 6 for the DTX) inspire no criticism, and the clutches are smooth and progressive.
But what about the DTX's engine?
Having had a DTR in my youth, I remembered its sharp but playful temperament. Yamaha has reoriented the mill towards more smoothness at the expense of top-end power. On the handlebars, you're faced with a machine with a very healthy chassis, armed with excellent Pirelli tyres that allow you to attack without a second thought. Unfortunately, as the engine has lost more than half its original power (from 30hp to 15hp!), you'll have to play with the gearbox to stay within the power range. The DTX's energetic behavior results in a fuel consumption of almost 6l per 100km, which allows a little 140km before reserve!
The two engines distill a different kind of "power", and the XTX's revs will make you wonder why Yam equipped it with a throttle, given that you're always going full throttle!
As for the DTX, the high power output gives you an enjoyable kick in the ass, especially as I'm still a 2-stroke lover!
The XTX rider will take advantage of your runs at the pump to catch up. He'll be happy with just 4l/100km, which means he'll have plenty of room to spare; with a sight glass every 170km, please!
So, let's recap:
The XT 125 X emphasizes its "wise" side:
- wise at the time of purchase, with a difference of nearly 1,200 Euros,
- wise at the pump, consuming 30% less (and let's not even talk about 2-stroke oil!),
- it's wise for short legs, thanks to its soft suspensions that settle more easily, and its 50mm lower seat height,
- wise in terms of its consumables, which are certainly less expensive
This bike is certainly an aesthetic success for such a small size. What's more, if you put a beautiful baby like me on it, with equipment worthy of a grand prix racer, you'll put a smile on every passer-by's face!
As for the DT 125 X, it's more of a "coup de coeur", a first step into the Supermotard sphere. A playful, well-equipped machine (with an excellent headlight, a rarity for an ex-enduro) that will turn all your daily commutes into urban specials!
