►The Paris-to-Dakar rally
is like no other off-road race in the world. It starts near the Eiffel Tower,
and ends in Africa, 22 days and 6500 miles later. In the fires of this
mechanical hell, where street engines scream inside dirt-bike chassis, Cagiva
forged its 650 Elefant. The Elefant is a creative collision of street and dirt
technology, combining the best of Cagiva's and Ducati's until now separate
worlds.
Understand, the dual-purpose Elefant on these pages and in
your dealer's showroom is not a look-alike imitation of Cagiva's racer as so
many "replicas" often are: Cagiva's Paris-to-Dakar technology translates
remarkably well to American pavement, making the Elefant far more rugged and
fast off road than any poser need be.
What
happens when a company follows the P-D formula of stuffing a street engine into
a dual-purpose chassis and turns the result loose on the streets and fireroads
of America? First, look at the bike's sheer size: Wheelbase, a touch over 60
inches. Seat height, 35 inches. Wet weight, 454 poundstwice that of a 250
motocrosser. Other street bikes vanish behind the towering Elefant: its seat
hits 600-class sport bikes at tank-top level; its handlebar measures chest high
to a six-foot rider.
For Ducati
lovers, running a desmo engine off road must be akin to burning pieces of the
True Cross for an after-ride campfire. Viewed more objectively, the choice makes
perfect sense. The Elefant's 90-degree V-twin engine (borrowed from the 650
Alazzurra) is a tough unit: desmodromic valve actuation protects the engine from
over-rev damage, and the engine cases proved unbreakable in 6500 miles of P-D
pounding. Though the Elefant and Alazzurra share basic engine specifications-82
x 61.5mm bore and stroke, 10.1 compression, valve sizes and included angle,
8500-rpm redline, and identical transmission ratios spread across five gearsthe
engine needed a little fine tuning for dirt service.
Off-road
engines soak up incredible abuse. Curiously, while the engine is solid mounted,
aluminum mounts and frame sections isolate it from the steel frame rails. We've
seen a similar approach before: Yamaha's old 250G road racer suffered cracked
engine mounts until aluminum plates were inserted between the frame tabs and
engine caseswhen vibration took its toll, replacing those plates was a good
deal less expensive than replacing the frame or engine cases. Though the
Elefant's 90-degree engine layout cancels any primary imbalance, some secondary
shakes, limited to a horizontal plane, remain. This, plus the enormous inertial
loads encountered off road with a heavy engine, make aluminum mounting a
sensible choice. Two alloy arms, extending from the backbone, hang the engine
from above, and an aluminum cross-member, running between the down-tubes,
supports the engine from the front.
The rear
mounting system is even more unconventional. Two huge vertically disposed
aluminum plates fit between the frame and gear case, attached to the frame at
the top and bottom engine mounts. The swing-arm pin runs through the frame
tubes, the plates, and gearcase. A swing-arm pivot through the back of a
solid-mount engine's cases is a great idea for the street, but off-road bouncing
would crack the cases without the reinforcement, and the Elefant's single-shock
rear suspension concentrates its loads in the gearcase-pivot area as well. Thus
the alloy plates not only spread the load on the engine, but provide top and
bottom anchors for the rear suspension.
Last
year's Elefant had relatively mild camshaft timing and smallish, 32mm Dell'Orto
pumper carburetors. This combination gave strong low-end punch but sacrificed
top-end power. Cagiva engineers fortified the '87 model's top-side performance
by fitting longer duration camshafts with more overlap, and larger 36mm
Dell'Ortos. These tweaks, in conjunction with exhaust system and SuperTrapp
spark arrester, improve the engine's breathing performance.
Look
closely at the Elefant's carburetors and you'll swear something's missing: the
rear carb. Ducati twins traditionally had their carbs at the rear of each head;
compared to Ducks of yore, the Elefant's rear cylinder head is backward, its
intake port facing forward, exhaust port pointing back. Cagiva didn't simply
rotate the head 180 degrees; the change required a completely new casting to
accommodate the cam's right-side belt drive.
Why all
the fuss? Cagiva needed room for the Elefant's single-shock rear suspension, and
wanted to give this and all their smaller twins a single air-cleaner housing and
more even intake plumbing. For off-road use, Cagiva had to have an efficient air
cleaner, but where to put it? Mounting the airbox conventionally above the
engine would have swelled the gas tank to grotesque proportions, so Cagiva
tucked the air-cleaner element under the seat and plumbed it to the carbs
through the frame's huge stamped-steel backbone.
Reversing
the Elefant's cylinder head both complicated and simplified its exhaust.
Positioning both exhaust headers on the right allowed the two-into-one exhaust
system to mount high, out of harm's way. The front pipe snakes beneath a
protective plastic bash plate under the engine, then climbs to join the rear
header just in front of the muffler/ spark arrester assembly. Unfortunately, the
Elefant's restrictive exhaust plumbing nicks horsepower off the top end: At the
strip, the Elefant posted a best quarter-mile run of 13.65 seconds at 95.3
mphunderwhelming for a street bike, while still impressive by dual-purpose
standards.
Since
off-road speeds are far lower than street velocities, the Elefant pays
particular attention to its cooling. Its rear cylinder is largely isolated from
the main air stream, so to cope with the additional heat, the bike uses a
seven-tier oil cooler located in front of the fuel tank. The cooled oil runs
directly to the single overhead camshafts in both, front and rear cylinder
heads. Oil capacity is also up over the Alazzurra.
Altering
the desmo engine for off-road duty was a cake-walk compared to building a
chassis rigid enough to house it. The Elefant's steel square-section,
double-downtube, full-cradle frame is quite a different approach from the series
of slender pipes that form the ladder-type frames in Cagiva's street bikes. Well
it shouldthe 650's engine weighs 133 pounds bone dry; that kind of weight
pounding across rough ground can crack a frame in a hurry.
The
Elefant's answer to this stress is mass: Everywhere in the Elefant's frame,
massive sections buttress massive sections. The box-section backbone measures
4.5 inches across its widest (rearmost) point, tapering down to 2.3 inches at
the steering head. Vertically, the backbone flares in the opposite direction,
smaller at the rear, over nine inches tall at the steering head. The main frame
tubes are 1.2-inch square, and the right downtube unbolts to facilitate engine
removal. The rear subframe, constructed of smaller square tubing, bolts to the
main frame and mounts a small luggage rack at the rear.
Positioned
vertically- behind the twin alloy swing arm/engine/shock mounting plates is an
aluminum-bodied Ohlins damper, with separate, external controls for compression
and rebound damping, and adjustable collars for spring preload. The top shock
eye mounts directly to the plates, but the bottom eye hangs on linkage, which
connects to the box-section aluminum swing arm and forward plates, and pivots on
a self-lubricating bushing. This shock itself is first rate: compression damping
is infinitely adjustable, the rebound adjuster offers 15 settings, and the
linkage provides eight inches of progressive-rate wheel travel.
The
Elefant's front suspension and running gear are equally impressive. Thick alloy
triple clamps hold an air-adjustable 43mm Marzocchi fork which strokes through
nine inches of travel. Straight-pull spokes lace alloy rimsa 17-inch rear,
21-inch frontto lightweight hubs carrying Brembo brakes.
The front
brake combines a 10.2-inch floating disc and four-piston caliper; the rear, a
solid-mounted 9.4-inch disc and dual-piston caliper. Does a dual-purpose bike
really need such serious brakes? If it weighs 454 pounds and generates as much
speed as the Elefant, it does.
The
Elefant likes to run in wide-open spaces, across the desert, down fast, sweeping
fireroads. The desmo engine is a powerhouse off roadsmooth, torqueyand the
rigid, long-wheelbase chassis provides unshakable highspeed stability. This,
combined with powerful brakes, excellent steering, near-perfect suspension
calibration and grippy Pirelli tires are the ingredients of a formidable
fireroad flier. Pitch the Elefant into a turn, and the front end bites. Feed in
some throttle, and the rear kicks into an easy slide. Take your pick: turn the
handlebar and steer with the front tire, or twist the throttle and aim with the
rear, dirt-track style. Either way, the Elefant is remarkably trustworthy,
stable, responsive.
An Elefant
is nevertheless a unique experience to ride. Size gives it a street-bike
presence off road; other dual-purpose bikeseven 600cc thumpersfeel tiny by
comparison. Tight, rocky trails exaggerate the Elefant's scale; fireroads put it
back into perspective. Sliding the Elefant through turns, you feel as if you're
riding a tall street bike- and getting away with murder. Terrific fun, yes, but
be warned: when 454 pounds of motorcycle gets away from you in the dirt, the
chances of snatching it back are slim.
And the
after-effects of even a moderate tip-over can be formidable on the Elefant.
Bailing off an uphill section, one tester was unable to get the bike upright
until help arrived. Our downed Elefant also dribbled crankcase oil through the
breather into the airbox, ruining the paper element and oiling the carbs and
plugs. To its credit, the Elefant survived the crash otherwise unscathed, proof
of the ruggedness of its components.
Canyon
roads are nothing more than fireroads with better traction, so it's no surprise
the Elefant works well here too. If you've never ridden a dual-purpose bike,
you'd be surprised how quickly they can carve the twisties, and the Elefant is
no exception. A wide, motocross-style handlebar makes for light, quick steering,
and virtually unlimited cornering clearance invites steep lean angles.
Conservative steering geometry and a lengthy wheelbase provide the Elefant with
high-speed stability unrivaled in the dual-purpose class. Though geared lower
than the Alazzurra, the Elefant has ratios tall by dual-purpose standards, and
the 650 pulls harder from corner to corner, with fewer gear changes.
Unfortunately, while our Elefant's hydraulically actuated dry clutch offers a
light pull, it dragged during testing, making it difficult to find neutral and
shifting stiff and notchy. The Elefant also uses stiff throttle springs that
pump up a rider's arms on the backroads.
If the
Elefant has a limiting factor in its off-road handling, it's the-Pirelli tires.
Universal-pattern skins strike a balance in on/off road traction, and while the
Elefant's tires are versatile performers, they quickly get skittish when pushed
on the street. Despite this poor traction, the Elefant's Brembo brakes offer
tremendous stopping power and excellent feedback. From 60 mph the Elefant's
shortest stopping distance was 136 feet, only two feet longer than it took to
haul the triple-disc Alazzurra from 60 to zero.
Street
riders will find the Elefant takes some getting used to: You sit high, the fork
flexes under braking, and the softly sprung, long-travel suspension allows
enough up and down chassis movement to have you reaching for Dramamine. For hard
riding, dirt or street, you must set the dampers on firm, but we found the
recommended settingsatmospheric pressure up front, and all rear adjusters in
their middle positionsoffer the best street/dirt compromise.
The
Elefant's long legs offer distinct advantages and disadvantages on the street.
Tall suspension invariably produces a tall seat height, and this makes the
Elefant near impossible to manage in stop-and-go traffic if you're under six
feet tall. The upright seating position feels perfectly natural on the highway;
only at speeds above 80 mph does the rider have to tug on the handlebar against
the wind. The seat is narrow and doesn't provide the support of a good street
bucket, but it offers enough comfort to sit through a full tank of gas, about
174 miles of steady-state running. At 75 mph, the desmo engine runs
effortlessly; though some engine vibration seeps through the gas tank, no
annoying vibes come through the handlebar or seat, and the footpegs feature
removable rubber inserts to damp vibration from the rider's feet. Full analog
instrumentation, and the best switches we've seen from Italy, enhance the
Elefant's highway experience.
Comfortable, versatile, quick, stable, ruggedthe Elefant is all these things,
but is it for you? Cagiva wanted to build a world-class replica of their Paris
to Dakar machine, and that's what they did with the Elefant. Consequently, this
dirt and-street 650 has its own quirky appeal: If your shoulders aren't broad
enough to hoist the Elefant back on its feet, or your inseam long enough to
reach the ground, or your pocketbook deep enough to spring for the $4,632
sticker price for a dual-purpose bike, kindly excuse yourself right here.
But if
you're still with us, picture this scenario: You strap a bedroll to the luggage
rack, dig out a map, and find a stretch of two-lane blacktop that runs out of
town, trips through the mountains, and dips onto a long, sweeping dirt road.
Follow that road until it runs out, then find another, and another in a string
of 200-mile days with lots of detours through dusty, forgotten towns.
Explore.
Ride. If that sounds like frivolity or eccentricity, look elsewhere. If it
sounds like paradise, so should Cagiva's 650. Either way, riding the Elefant in
regions that grow more exotic, more remote, more inaccessible, is the closest
thing to being out there, tromping on long, steady legs at speed across the
Sahara.■ |
