Driving report Yamaha XT 660 R / XT 660 X
Comeback to the power of two
The fans can breathe easy. Yamaha brings the myth XT back to life? in two model variants.
With all the hype about the new super athletes, it went under a little. The XT is back. And properly. Because who thinks Yamaha still has a couple of 2003 engines
Doing a little cosmetics around is wrong. On the contrary: all about a compact, largely newly designed,
water-cooled single-cylinder with injection and an overhead camshaft that now controls four instead of five valves via rocker arms, the Yamaha engineers have also knitted a new frame made of steel.
And because the trend towards the supermoto is also evident in the Japanese marketing departments, the XT is offered in two model variants. With the abbreviation R as a classic enduro from the old school, as an “X version” with smaller, wide 17-inch rims, a more handling-friendly geometry, shorter suspension travel, tighter chassis settings and more powerful front braking system than Supermoto. Before hardcore fans start screaming: Of course, neither the »R« with its deep-drawn manifold system is a competition enduro, nor does the »X« want to wrestle with thoroughbred Supermoto devices. Both should find their purpose in everyday motorcycle life? like the XT blessed.
An orientation that is reflected in the design of the engine characteristics. The goal was not absolute top performance, but a balanced torque curve and a distinctive single character. And both goals? so much is already clear after the first test drive around Sydney? were achieved convincingly. Despite modern injection technology with a twelve-hole nozzle and a 44 mm throttle valve diameter, the XT single-cylinder is a single of real shot and grain, in a positive sense. It may not have the speed of the BMW F 650 engine, but it is already out of the speed range in a robust manner
and feels in the middle turn-
number range noticeably well. In spite of the two huge, raised stainless steel silencers? XT drivers from the very beginning may wistfully remember the dainty single silencer from 1976? a brilliant single beat, which is accompanied by the characteristic and popular exhaust slap when overrun.
And: with a nominal 48 hp at 6000 / min and 58 Newton meters at 5250 / min, the single cylinder mobilizes enough power at all times to carry out the planned tasks
easy to meet. In strictly limited Australia, after a fairly short attempt, there were highly illegal 160 km / h on the digital speedometer, with a little run you are sure to get more. With an identical, relaxed seating position on the enduro-style, narrow, but somewhat uncomfortable bench seat on longer journeys, the large-wheeled R runs a little
more relaxed straight ahead. That’s what she plays for
X with its 17-inch front wheel, a 15 millimeter shorter wheelbase, three degrees steeper steering head and 28 millimeter shorter caster in narrow country roads and in the city. However, it is not quite as neutral with the wider tires in the lean position. The Supermoto has the advantage again in terms of feedback: the X, which comes with Pirelli MTR 01 tires as standard, reports more precisely what it is taking under the wheels thanks to the tighter suspension setting, while sister R springs and dampens somewhat softer. Even a little more balanced at the back.
Speaking of springs: Both models only have to be minimally with simple-
adjustable spring elements. Only on the shock absorber can the spring base ?? for example with pillion rider ?? adapt to the changed circumstances. Naturally, this does not work with braking systems. And so the Supermoto-XT is not only much better equipped than its enduro sister, especially in two-person operation with its 320 millimeter disc, the Brembo four-piston caliper and an additional stabilizer between the stanchions. It has to be content with a 298 disc and double-piston caliper. The former system brakes o, là là, the latter before
especially when it is cold, well.
After all, the Enduro can use as an excuse that a brutal brake bite on the front wheel off the beaten track is not necessarily an advantage and the rear stopper intervenes decisively. It works well with both XTs and has a solid effect.
Still does XT 660 R im
Series trim recreational off-roaders not perfectly happy? because the aluminum protection, which is urgently needed in view of the manifold underneath the engine, is only available as an extra at an additional cost of 162.50 euros. And a
closer graduation of gears two and
three, which would be very desirable, is not even for both models
Money and good words available.
However, this small mishap does not significantly cloud the positive overall impression of both XTs. Both are more straightforward-
te, solid jokers with a refreshing appearance. Precisely because they forego unnecessary frills and instead offer motorcycling in its original, thoroughly honest form. That should not only inspire old XT warriors, especially since the price of 6350 euros for the R and 6750 euros for the X variant is still well below the good 7250 euros that BMW, for example, charges for the F 650 GS.
