Honda's VFR1200F DCT and Ducati's Multistrada 1200 S are leading the
charge with sophisticated electronics packages that turn them into
something new: Smart Bikes.
Honda has chosen to focus on the transmission. A company that has
long been fascinated with alternative methods of transmitting power from
the crankshaft to the road, its fully automatic six-speed Dual Clutch
Transmission (DCT) eliminates the conventional hand- and foot-levers,
and saves the rider the effort of operating them.
Ducati has gone in a different direction with the Multistrada 1200
S. Although mechanically it is relatively conventional, the bike uses
electronics to maximize the capabilities of the motor and suspension, no
matter what the prevailing conditions.
We took both of these motorcycles out on extensive rides, learning
far more from them in tandem than we ever could have individually. What
they had to tell us was quite insightful. Smart Bikes, indeed.
2012 Ducati Multistrada 1200 S
Ducati's "four-bikes-in-one" claim for the Multistrada 1200 is
c
ertainly an audacious one. To make it a reality, Ducati equipped the
Multistrada S (both the Sport and Touring versions) with some dazzling
electronic wizardry that changes the Superbike-derived motor's power
output and delivery, manages traction control (DTC: Ducati Traction
Control) and ABS, as well as adjusts the Öhlins suspension (DES: Ducati
Electronic Suspension) to change the ride and handling.
Ducati has done an excellent job with the stock settings and the
Sport, Touring, Urban, and Enduro presets take a hugely powerful,
lightweight bike with a tall chassis and upright seating position, and
allows you to exploit it in a virtually unlimited variety of riding
conditions.
In addition to the presets, the Multistrada owner can go deeper and
personalize those modes precisely to his own requirements. You can also
easily alter the suspension pre-load (on-the-fly with your left thumb)
by choosing one- or two-riders, and luggage or luggage-free.
While not a sport bike ergonomically, in Sport mode the Multistrada S
will hang in there impressively on fast rides. It feels and reacts like
a sport bike; if it wasn't for the upright ergonomic layout, it could
probably show a clean pair of heels to Ducati's own 848 EVO Superbike.
The suspension is firm, and the torquey 1198cc Testastretta 11˚ motor
pulls hard and revs eagerly to redline. The Sport throttle response is
so cracking that wheelies are enticingly easy, as the DTC is set to a
relatively non-intrusive mid-level 4. Because the Pirelli Scorpion Trail
tires are a compromise for the street, it is not difficult to slide the
rear on aggressive corner exits, so the traction control is welcome.
When not trying to leave rubber on the road, the Touring preset still
gives you access to the 150 horses it does in sport, albeit with a
softer initial delivery. The DTC becomes a little more intrusive at
Level 5, and the suspension gets softer, though not quite plush. When
you ride smoothly, Touring mode is sporting enough that you can still
enjoy some comfort on spirited mountain rides without a significant
handling sacrifice.
In town, Urban mode lives up to expectations. Maximum horsepower is
tamped down to a still considerable 100, with a modest delivery.
Softening the suspension and moving the DTC up to Level 6 allows you to
be aggressive with the throttle and ensures that speed bumps, drain
covers, and other road obstacles are swallowed up without bucking you
off the bike.
We did forget to switch out of Urban for one trip into the canyons.
After unexpectedly dragging the pegs hard in a couple of turns, a look
at the display reminded us that the Multistrada was in the soft Urban
setting. Pushing the turn signal cancel button toggled through the menu,
and once returned to Sport mode the dragging immediately ceased.
Though our dirt excursions were limited to unpaved roads and easy
trails, the Enduro mode did not disappoint either. Traction control is
almost gone at Level 2; the DES lifts the rear end for more ground
clearance, while the suspension remains very compliant. As in all modes,
the ABS can be switched off.
The choice of four types of riding-and within each type, four load
options-should be more than satisfactory for most riders. Of course, in
many cases, Ducati riders are not "most riders." Recognizing that,
Ducati gives us access deeper into the DTC and DES settings.
The highly sophisticated DTC takes speed info from both wheels and,
when a discrepancy is detected, it firstly retards the timing, and
secondly restricts the fuel/air mixture to reduce torque output.
Depending on the situation, this happens transparently (much of the
first stage) or quite audibly (in the second stage). To make sure you
appreciate the DTC, a red circle flashes around the mode display when it
is active.
Specially designed in partnership with Ducati, the electronically
controlled Öhlins suspension (DES) is an industry first and fully
integrated into the riding modes. Servos built into the forks and rear
shock fine-tune rebound and compression damping, and also manage the
spring preload on the TTX shock.
With all these systems working in harmony, the result is thousands
of possible combinations of DTC and DES settings. Only four Modes in
total can be saved, and the preset names cannot be changed. Fortunately,
if you over-correct the settings and the result is unsatisfactory,
Ducati has a reset option that returns everything back to stock.
The Ducati Multistrada S is a smart bike, imbued with the full brain
trust of a staff of test riders whose collaboration gives us four well
thought out standard modes. It is also a bike that is willing to learn,
as those are but a starting point. - Don Williams
Honda VFR1200F DCT
The VFR1200 DCT (Dual Clutch Transmission) is at the zenith of
Honda's technical prowess. Even the new paint process and patented
layered fairing are technical tours de force. After a white-knuckle
scare on a sand-covered road, I can also confirm that its anti-lock
brakes work flawlessly and prevented an expensive and embarrassing
tipover.
However, the DCT is a polarizing topic of conversation between
riders. Yes, one can easily dismiss the DCT with the "If it isn't
broken, don't fix it" argument. Still, from a technical perspective, it
is intriguing.
Essentially two gearboxes integrated together, one clutch handles
ratios 1, 3, & 5, and the other, ratios 2, 4, & 6. The
electronics flip between the two gear clusters, and because the next
gear is pre-selected, changes are seamless, smooth and swift.
There's no torque converter, so the engine is mechanically connected
to the rear wheel. Every revolution of the crankshaft equates to
incremental movement at the rear wheel, and that translates into feel at
the throttle and engine braking into corners. The VFR acts like a
normal motorcycle, not an automatic transmission car.
Operation is simple. No foot movement is involved, as a thumb switch
on the right side selects and toggles between Drive (D), and Sport (S)
as desired. Moving away from a standstill requires no more than careful
use of the throttle; the centrifugal-type mechanism engages
transparently and super-slow maneuvering can be accomplished with ease.
All gear changes are then (by default) automatic, and although first and
second clunk a little due to some transmission slop, the process is
generally much smoother than a human could achieve.
D mode short-shifts into top as quickly as possible; you will almost
find yourself in sixth before leaving the parking lot. Fortunately, the
engine is so torquey it doesn't make much difference to the actual
riding experience around town. If you are just pottering around then
leave it in D and focus on the driver texting/tweeting/phoning in front
of you.
When you need some sudden acceleration, you must grab a big handful
of throttle to make the gearbox downshift-it doesn't notice subtlety and
takes its time. That split-second delay prevents you from instantly
accessing the hefty 95 ft/lbs of torque the VFR puts out. If you start
riding aggressively in D mode, the bike doesn't necessarily downshift
into corners, and the lack of engine braking can be a little
disconcerting if you're hard on the brakes.
S mode is more suited to twisty roads as the lower gears are held
longer, and the system downshifts when you brake strongly. For spirited
riding it works well, but once you are straight-line cruising, the
transmission uses fifth as top gear and so the motor feels a bit busy.
At that point, it is easy to switch into D mode or manually select
sixth.
You can toggle between Manual and Automatic shifting using the
forefinger pull switch on the right handlebar, and the VFR1200 will stay
in Manual without defaulting back, even if the motor is held at
redline. Manual mode is also selected by using either one of the gear
change switches on the left handlebar-thumb button for downshifts, and
forefinger switch for upshifts. The switches are light and intuitive to
operate. I was surprised how quickly I adapted, although I confess I did
mistakenly hit the turn-signal cancel a couple of times.
Fully committed riding requires Manual mode, as Automatic shifting
typically chooses ratios one too tall for my taste. So, Manual mode is
where the DCT really shines. The VFR changes gears swiftly and with only
the tiniest of finger/thumb movement at the handlebar. I found it
especially useful through fast left corners when I was leaned over hard
and had to change up through the gears. Instead of having to unweight my
left foot and hook it under a lever, all I had to do was flick the pull
switch.
When you are preoccupied with a road that is rapidly unraveling in
front of you, the VFR's functionality in Manual mode is extraordinarily
useful. It is the normal motorcycle we are used to, albeit with a much
more efficient, and smooth, method of changing ratios.
Downshifting gives engine braking as normal, and the interaction
between the two clutches obviates the need for blipping the throttle; it
is uncanny how well this system works. Coming down from high speed into
a very slow corner, you cannot thumb down several ratios rapidly as
with a conventional gearbox and slipper clutch, but that didn't bother
me on the street.
Your feelings toward the DCT will depend on how you are riding. You
can never select the wrong mode, per se, but in an unsuitable one you
can find yourself wanting-and waiting-for a different ratio. Typically,
this is more irritating than scary.
When you match the mode to your riding, the DCT is awesome. It makes
in-town riding a simple no-brainer, and fast canyon riding an easy
adventure. If you are fully dedicated to riding hard, then Manual mode
helps you focus on the road conditions. It saves on labor without
sacrificing any control-that is what we want, isn't it?
The VFR1200F DCT's technology is impressive and the transmission is
genius, though Honda could add traction control to help contain some of
that prodigious torque output. Having lived with it for a while, I began
using it as naturally as a conventional transmission, and when I got
back on a "normal" bike, I missed the Honda DCT-very much. - Arthur

Conclusion
Ever since Monsieur Michaux attached a small steam engine to his
velocipede, motorcycle technology has steadily developed-sometimes by
leaps and bounds. Pushrod twins in the 1960s were crushed by Honda's
overhead-camshaft four; '70s-era two-strokes blew away the four-stroke
multis; and the '80s saw the advent of grippy radial tires that opened
the door to serious performance.
In recent years, motorcycle development has plateaued somewhat.
Sure, every manufacturer points out how this year's whizz-bang model is
so much better than last year's old nail, yet the truth of the matter is
that modern sports motorcycles are, in general, so powerful and so good
that only professional roadracers can fully exploit their capabilities.
The power of microprocessors has brought another leap forward, and
manufacturers are able to enhance rider safety with the use of
electronic aids-fuel maps can be changed to curb horsepower and soften
delivery; anti-lock braking systems are often transparent in operation;
traction control is so sophisticated that competitors can adjust it
incrementally during a race.
Both the Ducati Multistrada 1200 S and the Honda VFR1200F DCT
motorcycles are indisputably technologically impressive. In each case,
the technical option adds to the price, and a cheaper, simpler version
is available should you prefer it. So the big question is: do these
technical advancements actually bring something really worthwhile to the
rider, or are they just fanciful experiments that only an engineer can
appreciate?
Our initial expectation was that we would write off the DCT as the
answer to a question no one had asked. Why do we need automatic shifting
when the conventional version works so well? We were surprised, shocked
even, to discover that not only did we appreciate the DCT the more we
lived with it, but eventually-gulp-we preferred it!
We developed the same affection for the Ducati's multiple riding
modes and electronic suspension. Much of the staff grew up in the '70s
where the handling of a bike was changed by how you rode it, and any
vagaries were just ignored. So we suspected we would gravitate towards a
favorite riding mode and then pretty much forget it. Nothing could be
further from the truth.
With varied roads and continually changing traffic conditions, we
found ourselves frequently taking advantage of the Ducati's
adaptability. The differences between the modes are obvious and
significantly affect the Multistrada's performance. Confidence increased
and, on more than one occasion, we were kept safer as well.
Man actually needs very little beyond food, shelter, and air.
Happily, modern society has brought us some astonishing technologies
that help make our lives easier, safer, and more comfortable. Although
motorcyclists have typically been less than welcoming toward some of the
technological advances, if we do not sacrifice control, then we suggest
that advancements on motorcycles should be greeted with enthusiasm.
