Truly distinctive motorcycles are hard to find these days.
There's no question that the Japanese build motorcycles that are unmatched for
variety and unequalled for cold, calculated performance; nonetheless, there's a
generic similarity about all of them, a certain antiseptic, fault-free sameness
that is absent of any discern-able character. For the most part, they lack heart
and soul.
When viewed against such an homogenous backdrop, Laverda's
RGS1000 Corsa oozes character from every nook and cranny. This triple-cylinder
hunk of Italian exotica has the kind of quirky behavior and rough-edged
personality that is typical of products built by small-volume manufacturers.
Visually, its massive engine and hulking silhouette hint that this is no
namby-pamby motorcycle, and functionally, its high-effort operation confirms
those suspicions.
Indeed, riding the Corsa fast on a twisty ribbon of asphalt
requires more concentration than finesse, demanding the rider's undivided
attention. If the leading Japanese-built sportbikes dissect
the swervery with the precision of a scalpel, the Corsa rips
and snorts down the road like the world's fastest chainsaw. Its suspension is
taut, its steering is heavy, its controls are stiff, and its three-cylinder
engine thunders out its power in a way that never, ever, lets you forget that
it's down there working. In all, the bike is about as subtle as a poke in the
eye, and about as comfortable, too; but those who can look no further than the
Corsa's faults will never see its true—dare we say endearing character.
Unlike Japanese motorcycles, which usually are an embodiment
of the high-volume marketing strategies that emerge from committee planning
sessions, the Corsa is a reflection of what one man, Massimo Laverda, believes a
motorcycle should be. His brainchild is pretty much an anachronism in America,
where stoplight-to-stoplight spurting is of paramount importance and
leading-edge technology is in great demand. But that's okay with him, for he
knows that in Europe, where the vast majority of his bikes are sold, riders
prefer a proven machine that can sustain high average speeds with long-legged
strides and unwavering stability. And it is this bike's appetite for fast,
winding, European-type roads, combined with Massimo Laverda's refusal to build
stoplight racers or please-all appliances, that gives the Corsa its soulful
personality.
This does not mean, however, that Se-nor Laverda lacks the
desire to refine his products, nor that his company has totally ignored the
needs of the American rider. This Corsa is far more civilized and emits much
less mechanical clatter than any Laverda Triple before it; and our test Corsa
launched through the quarter-mile in 11.91 seconds at 112.81 mph, meaning that
it not only is the quickest production bike ever to bear the red, white and
green Laverda logo, it's also the quickest European motorcycle you can buy.
Moreover, the two-valve-per-cylinder Triple produces broad-range power that
extends from idle well past the 8000-rpm redline, with a rush of top-end
horsepower and a willingness to rev freely that are uncharacteristic of previous
Laverda engines.
The Corsa's ability to rev past the red zone like the hottest
Japanese superbikes is due in part to a number of minor, but effective,
weight-paring improvements within the engine's massive sand-cast cases.
Reciprocating mass has been reduced through the use of thinner, lighter
connecting rods, shorter piston pins and forged pistons that are lighter than
the cast pistons used in the previous incarnation of this Laverda Triple, the
Jota 1000. The forged pistons also resist heat expansion more effectively than
cast units, thus allowing smaller clearances that enhance the sealing properties
of the rings, that improve heat-transfer to the cylinder walls, and that reduce
noisy piston-flutter, all of which extend the service life of those
power-producing components.
Most of the Corsa's newfound performance, though, is brought
about by redesigned camshafts and larger intake valves. The combustion chamber
already was crowded, so the exhaust valves were decreased in size to accomodate
the bigger intakes. The valve lift was upped slightly, but the duration of the
cams remains the same as on the Jota.
What these changes mean is that the Corsa produces more power
than the Jota everywhere in the rpm range, with crisp response to throttle
inputs at all but very low revs. Below 2000 rpm, the Corsa's throttle response
is jerky and irregular. We suspect that this ill behavior is a result of a very
abrupt ignition-timing advance that occurs around 1800 rpm, combined with the
lean carburetion needed to get the Corsa past the EPA's emission requirements in
general, and California's even stiffer CARB standards in particular. Beyond that
point, the 981cc engine delivers smooth, steady, uninterrupted power, although
it pulls strongest from around 7000 rpm up to— and well beyond—its 8000-rpm
redline.
In the interest of appeasing American riders, who aren't as
likely to compress their riding days with 90-mph-plus jaunts on the backroads as
the Europeans might be, the first three gears in the Corsa's five-speed
transmission have lower (higher numerical) ratios, with two more teeth on the
rear sprocket compared to the Jota. This makes it easier to keep the Corsa
spinning in the meaty part of its powerband without having to exceed the
national speed limit by a factor of two; and it also has reduced what once was a
sizable gap between ratios.
These changes, with the aid of extensive sound-deadening
refinements inside the engine, make the Corsa a more live able and civilized
motorcycle. The engine cases are now thicker and incorporate more ribbing to
baffle engine noise, and the crankshaft and transmission mainshaft no longer
turn in bearings located in the outer cases. Instead, these shafts run in caged
rollers supported by outriggers bolted directly to the engine block, thus
reducing the amount of mechanical noise transmitted to the outside world. In
addition, the Jota's triplex primary-drive chain has been superseded by two
separate single-row chains that run much more quietly.
Still, the greatest improvement in the Laverda's civility is
the result of the most radical departure from the Triple's original design: the
adoption of a conventional (for a three-cylinder engine) 120-degree crankshaft
rather than the unusal 180-degree crank used previously. The 180 crank—with its
two outer pistons moving up-and-down in unison and firing alternately, and the
center piston phased 180 degrees apart from the other two—virtually eliminated
the rocking couple that is present with a 120 crank, but caused considerably
more primary and secondary imbalance, enough, at times, to rattle the rider's
fillings loose. Not so the 120 crank, which produces a much smoother power
delivery and, aided by the evenly spaced power pulses and rubber engine mounts,
also passes less vibration up to the rider.
But while the Corsa's engine is certainly more agreeable than
the Jota's ever was, it's still not much of a utilitarian workhorse. There's a
noticeable amount of vibration felt through the handlebar and footrest and seen
in the smallish, fairing-mounted mirrors. And despite having an improved
shifting mechanism, the gearbox clunks during gear changes and the shift lever
requires a long throw. European riders may not be as bothered by these traits,
however, because the Corsa smooths out considerably once it is locked in top
gear and dialed up to stratocruise speeds.
To be sure, the Corsa devours huge chunks of country landscape
with remarkable ease. Its steering garners high marks for precision and response
at triple-digit speeds, with its firm suspension, sturdy frame and sticky
Pirelli tires providing confidence-inspiring stability and sure-footedness.
Compared to the Jota, the Corsa has a frame that is lower in
the rear to bring down the seat height, but sub-six-footers still will find it
impossible to plant both feet flat on the asphalt. This change has, however,
positioned the rider a little closer to the ground, which also lowers the
overall center of gravity. That's why the Corsa is a bit easier to flick into
turns than the Jota was, especially for riders who don't hang off when cornering
in full-sport mode. Nevertheless, the Corsa still steers more heavily and slowly
than any of the current Japanese superbikes.
Other chassis refinements include a juggling of the frame's
backbone tubes to facilitate easier engine removal, along with recalibrated
Marzocchi suspension components. Though still using twin, gas-charged rear
dampers and a front fork incorporating 38mm stanchion tubes, the suspension now
features softer springing and less rebound and compression damping than on the
Jota. The result is a noticeably smoother ride and quicker response to sharp
bumps. Compared to the best Oriental offerings, and to the more closely related
BMW K100RS, the Corsa's supension still is too unyielding to offer much in the
way of all-day comfort. Riding the Laverda at a pace it seems most comfortable
with fast but fluid the suspension is too harsh to insulate the rider from
small- to medium-size bumps, and it lacks sufficient rebound damping to
complement the firm springs.
It's not until you begin to push the Laverda to its limits
that the suspension and steering geometry make much sense. Despite the effort
required to initiate a turn on the Corsa, the steering remains dead-neutral at
all speeds, and the bike exhibits little tendency to sit up when the rider
brakes deep into a turn. Once the desired line through a corner has been chosen,
the bike settles in nicely and shows no tendency to bolt, even when the rider
momentarily relaxes.
At a more sedate pace, the Corsa feels long, tall and
top-heavy, especially when you're trying to herd its 558-pound heft into a tight
turn or through city traffic. Laverda has experimented with steering-head angles
ranging from 27 to 30 degrees throughout the Triple's lifetime; and it is
obvious that the Corsa's numbers 29 degrees, with 125mm of trail cater
more Euro-riding than to American preferences. On the wrong road generally
one with a lot of tight corners the Corsa demands constant attention. You find
that it will wear you out quickly if you ride it extremely hard, and that snap
transitions can be made only if you plan ahead and use a decided
grunt-and-force-it technique.
There are other incentives to keep the Corsa off of
ultra-twisty roads and out of city traffic. Though hydraulically actuated, the
clutch pull is quite stiff, requiring a strong hand for repeated usage. The
throttle-return springs fitted to the DeirOrto accelerator-pump carbs are stiff,
as well, and the twistgrip requires about 30 degrees more rotation than usual,
forcing the rider into all sorts of right-wrist gymnastics to reach full
throttle. And while the Brembo front brake is powerful, it, too, requires high
lever-pressure to be fully utilized.
Aside from those high efforts, though, the brakes are hard to
fault. The European version of the Corsa doesn't have the floating-type brake
discs found on the American model (but does have more-radical cams and taller
final-drive gearing); and unlike the European brakes, which lose much of their
feedback when they get hot, the floating system on the U.S. model allows the
discs room for heat-expansion so the brakes can continue to send the rider clear
messages when the going gets fast. The rear brake, though, could be a bit more
sensitive to inputs from the rider.
So, too, could the Corsa's seat be more sensitive to the needs
of the rider. The seat is high-crowned, hard and, after more than an hour or so,
excruciatingly painful to sit on. But otherwise, the Laverda's ergonomics are
roomy and comfortable. True to the bike's Continental sport-touring heritage,
the seating arrangement makes the rider bend at the waist and rest most of his
upper-body weight on his hands. This position can be tiring at low speeds, but
out on the highway enough wind sneaks around the frame-mounted half-fairing to
push on the rider's torso and take some of the weight off of his hands. Yet at
highly illegal speeds, there is not enough wind noise or buffeting behind the
fairing to be disturbing, and weather-protection is excellent, as well.
RG Studio in Italy (hence the RGS designation) designed the
fairing, along with the unique, smooth-top gas tank that has its filler opening
behind a trapdoor at the right-front of the fairing. RG also supplies an
optional cowling that fits over the passenger section of the seat and turns the
Corsa into a solo machine. The cowling allows the rider to brace himself against
a padded butt-rest, which takes some of the effort out of hanging on during
spirited backroad workouts, and it also provides storage space for small items.
Equally clever are the Corsa's adjustable footrests. Carried
on circular plates mounted to the aluminum footpeg/muf-fler brackets, the rider
pegs can be rotated 360 degrees (and thus moved back-and-forth or up-and-down)
by simply removing an Allen bolt on each side and loosening the lock-nuts
securing each peg. All in all, the system provides nearly two inches of vertical
and horizontal adjustment of any size.
Laverda also offers a host of options for the Corsa, including
a higher handlebar with accompanying hardware, a set of color- and style-matched
sport-touring luggage, and a 3-into-l exhaust system. We used the stock 3-into-2
exhaust for part of the test (including the gathering of the performance data),
but spent most of the time with the optional system in place. It seems to
bolster the Corsa's power a bit in the midrange while not making a noticeable
performance difference anywhere else. It is lighter, though, and at
full-throttle, a bunch louder.
But that's right in keeping with the Corsa's imprudent overall
personality. Despite its ongoing refinement, the bike still is fundamentally a
crude device compared to the best the competition has to offer. Most Japanese
sportbikes not only can outgun the Corsa on the straights and through the turns,
but also are more comfortable, less quirky and a bit cheaper, to boot. Based on
past performance, though, at least a Corsa owner can expect his trusty mount to
endure, for Laverdas have proven mechanically bulletproof if nothing else.
So those who ply their skills on Oriental weaponry undoubtedly
will find it easy to assassinate the Laverda no matter what. The bike is like a
Roman warrior who headed into battle sheathed in steel armor: He was hard to
pierce but an easy target nonetheless. So it seems logical that the average
rider will find dis-couragingly little about this beast from Breganze to admire.
But the not-so-average rider, the person who stays as far away
from mainstream motorcycles as he possibly can in favor of something with more
individuality, just might find a good friend in the Laverda. See, the RGS 1000
Corsa is more of an end in itself than it is a means to another end like so many
other motorcycles. It's a traveling companion, not a transportation contrivance.
It's appealing because of what it is, not because of what it can do.
That's simply another definition of
