Overview
KTM 640 LC4
Adventure Traveller Edition
Designing the 640 Adventure Travellers Edition,
KTM people intended to obtain a smaller version of the 990 Adventure, so it is
obvious why were facing a ready-to-go-anywhere looking machine.
KTM is a Dakar master so when it comes to Dual Sport machines the fairing and two small headlights
are a must. Aerodynamic looking and ready for the long haul, the Travellers Edition is one uniquely styled bike. The color is, of course, KTM orange.
Like a true desert machine, the 640 features a bigger front wheel (21) for easy dealing with the bumps and the rear wheel (18) is there to provide tractable power in any situations. The rims are black so that they would create a nice contrast fairings color. So is the seat.
Inspired on the much bigger,
Paris-Dakar winning motorcycle (KTM 990 Adventure), the 640 Dual Sport
motorcycle presented by KTM retains only the good features such as
versatility, agility, power and gets reed of the unnecessarily weight and
size, resulting in an easy to ride all around motorcycle with plenty of
power coming from the LC4 single-cylinder engine which proved successful on
many KTM models (the Duke, SMC, LC4).
During the time
Ive ridden KTMs
640 Adventure I
saw a new
face of
motorcycling and I
sure loved it.
Attraction immediately
came as I
jumped onto its
seat and fired
up the
four-stroke 625cc
single-cylinder motor. The
riding position
is perfect for medium sized persons, just like me, and the exhaust note is deep, making the rider well aware of where the rpm level is all the time.
Putting the bike into first gear doesnt involve
any fatigue and the clutch feel is firm and precise. Having
ridden KTM bikes fitted with the same engine, I was now expecting a quick go coming from the single-cylinder, but I must say that throttle
response, although immediate, was tuned towards trail riding so it is a bit smoother and reassuring.
The engine is enough powerful
for almost anything that the off-road will require:
climbing steep hills, passing through
rivers, and spreading dirt. You name it and the 52 horses at 7000 rpm will deal with, problems excluded. It will also be the result of a torquey engine (55 Nm at 5500 rpm) which provides all of the tractable
power that gets you out of trouble and very often impresses
your buddies. I had no problems taking the 640 Adventure in deep mud and then wash it as I passed the river (my feet were already wet and the boots needed to be cleaned anyway,
so what better method?).
Also out on the trails I managed to get the front wheel off the ground by suddenly
twisting the throttle and it was quite a pleasure to do this as the terrain ahead presented
many step-like bumps. Impressive pull
saves the day!
But this type of exploitation
also requires good-performing suspensions and
the WP front and rear units are more than suitable for the job. I did not manage to reach the forks bottom end more than two times and that happened while landing
from an ambitious and optimistic
jump above a thick log.
The front brake played a trick on me (or I may have played a trick on the front brake) on wet grass surface,
determining the front wheel to slip and the rider to taste some muddy grass. It is more of a talent thing than efficiency
as you have to calculate how much to pull the lever, taking in consideration
the fork compression and the grip of the surface youre on. I guess that this is why Ive never seen an off-road rider
with no broken bones. On normal, street use, the performance Brembo brakes which
apply their pistons on two 300mm discs up front and a single 220mm disc at the rear prove very efficient
and confident-inspiring. I preferred using
both brakes because I didnt wanted to taste the asphalt (I reckon that this ride report would have been published
pretty late). Even so, it is steady and confident under powerful braking.
Ive taken the bike down the freeway and up to 80mph so I would get a feel of those harsh
vibrations that tend to make customers avoid it and I must say that evolution
has clearly said its word and even though
present through the handlebars and
footpegs, the vibration levels are acceptable and easy to live with. Would you preferred the engines grunt to fade away concomitant
to the rpm
increase? I dont think so.
Conclusion
A wonderful mix of power, versatility and
fun is what makes the 640 Adventure Travellers Edition a true blast each time you ride it. Prepared for the long run on and especially
off the road, the bike is a true representation of KTMs dedication on
delivering the best performing and
one of the
most agile all-around motorcycles on
the market today.
