Road Test 1989
Before the first Virago hit U.S. shores in 1981,
Japanese motorcycle companies had followed an unspoken agreement that the big
V-twin niche was reserved for America's own manufacturer. Yamaha slyly skirted
the unspeakable by making the Virago a different sort of machine—one that nicked
rather than blew away the Milwaukee bull's-eye. It was an immediate success.
But once Yamaha's toe was in the door, there was
no closing it. Other Japanese factories throbbed their way into America's
garages with their own V-engined customs. By 1984, Yamaha marketing experts
couldn't help noticing the success of Honda's Magna and Shadow 750s—far closer
H-D clones than the Virago. Buyers responded to the additional flash, and to the
more traditional Yankee look.
While the Japanese manufacturers were just
beginning to open point-blank fire at one another on the sport bike front, many
American motorcyclists-58 percent of new bike purchasers in 1983, to be
precise—cared little about those machines. Of a total 400,000 street motorcycles
sold in the U.S. that year, 233,000 were "cruisers."
In 1984 the Virago's loins were re-girded
accordingly. Twin shocks replaced the original Monoshock rear end, footpegs were
mounted way up front on the engine cases, twin chrome pipes flowed from the
exhaust ports, and a sissy bar sprouted aft of a more stepped seat. The more
American Viragos moved like proverbial hotcakes, and a lesson was learned.
Custom cruisers didn't need LCD instrument clusters and sophisticated on-board
computers, like the '82 XV920 Virago had; they needed simplicity, and style, and
big throbbing engines.
That 1984 Virago is still with us today with even
more throb. Its original 981 cc displacement was obtained by boring its 920cc
predecessor 3mm larger; and in 1986, a stroke increase pushed displacement to
its current 1063cc size. Though flywheel weight was also added with the stroke
increase for smoother power delivery, the air-cooled, two-valve, oversquare
Yamaha still is the most free-revving of the big twins as well as the smoothest.
Speaking of rpm, tables turn very fast in the
international motorcycle business. In sobering contrast to the 233,000 customs
sold in 1983, the motorcycle industry sold just under 92,000 last year according
a Yamaha official—and a third of those were Harley-Davidsons. The price gap that
once made Japanese customs impossible to ignore has all but evaporated. The
Virago is still at the bottom of the price line at $5500, with Suzuki's big
Intruder occupying the high end at $6500. But all big Japanese cruisers are now
priced dangerously close to 1200 Sportster territory, and Yamaha expects that
Harleys will account for fully half of the custom market in the 1990s.
Custom cruisers still accounted for 32 percent of
Yamaha's total cycle revenue last year, so there can be no thought of
discontinuing the line, but the sagging dollar also renders expensive upgrading
unfeasible. This year's Virago differs from last year's in color only. In the
Virago's case, that's not a bad thing.
Sport-bike riders who sight along their noses at
the Virago might be surprised at how well it works on unfamiliar two-lanes. The
Virago has no intention or chance of sucking headlights from GSXRs, but it's no
pooch either. Pumping 6 to 8 psi of air into the fork (one valve fills both
tubes) cures its mushiness, and gives reasonable medium-speed ground clearance
while still allowing amateurs the distinction of peg-dragging and showing off
planed heels. You can usually just leave the transmission in fifth. What's this?
Unexpected decreasing radius curve? Roll off the throttle and chassis attitude
barely changes thanks to the stiff rear shocks and pumped-up fork; roll back on
when the coast is clear and accelerate smoothly away. Virago brakes are the best
in cruiserville, light and powerful.
The Virago is the lightest and quickest steering
of its big-twin competitors, despite 32 degrees of rake and 5 inches trail.
While rake and trail numbers like those were last seen on a sport bike in the
early seventies, they are relatively steep and short by current custom
standards. At 537 pounds wet, the Virago undercuts the next lightest cruiser—the
1400 Intruder—by 36 pounds. It's also the shortest, with a wheelbase of 60
inches in a class where the norm is 4 or 5 inches more. The smallness of the
bike once cramped taller riders, but last year's revisions included a handlebar
bend that moved hand position forward 1.6 inches and upward 1.3, and footpegs
were pushed almost 2 inches forward.
While Yamaha may have reacted to complaints about
the cramped riding position, it still has work to do on the rear shock
absorbers. Set to the least pre- loaded position, the springs are too stiff for
riders under 150 pounds, and the ride is worsened by unsophisticated compression
damping. That can be painful on the Virago, which positions all the rider's
weight squarely on his coccyx. The shocks are adjustable for rebound damping,
but it's difficult to tell if twisting the collars really has any effect other
than to satisfy the rider's need to tinker. The Virago's rear end spends a lot
of time in the air over rough roads if you insist on speed.
As in the first Virago, the engine hangs from the
pressed steel backbone via oversize cylinder head studs, and it is still one of
the more polite large-displacement twins on the road. Vibration is no stranger
to big twins, and the Virago is no exception, but its shivering never becomes
bothersome until rpm exceeds about 4000. By 4500 rpm, the handlebar begins to
feel like a high-voltage cable; footpegs and seat, and the rider's eyeballs join
in around 5000. Redline is set at 7000 rpm, but there's no reward at all for
revving the engine that far. Any speed beyond about 75 mph or 4200 rpm is really
not what this bike is about. The Virago would benefit from taller gearing; in
top gear its big engine spins nearly as fast as the 647cc Honda Hawk's.
Other than high-speed vibration, the Virago
engine gives little cause for complaint. While its 54.1-horsepower peak at 5500
rpm may not seem high, more telling is a torque curve that starts as low and
stays as flat as the Gulf Coast of Texas. The Virago engine pumps out 50
foot-pounds at 2000 rpm; it peaks at 54 foot-pounds at 3000 rpm; and it holds
above 50 foot-pounds until past 5500 rpm. That's the kind of low-speed,
short-shifting grunt that V-twins are famous for, but don't always deliver.
The bottom-weighted power curve combines with the
Virago's light weight to make it the quickest big V-twin cruiser: It covers a
quarter mile in 12.90 seconds at 98 mph. That's about the same performance as .
our Harley FX project bike after modification, and quicker than any of the
Japanese competition.
If you're not bent on speeding, long distance
travel on the Virago can be surprisingly pleasant, provided you pack something
soft on the pillion to provide back support—otherwise, as with most cruisers,
hands and lower back fatigue early. The Virago places its rider in a rearward
list, and without something to lean on at speed, the task of staying on the bike
falls entirely on the wrists and on the step in the seat. That seat is
excellent, considering its difficult task of supporting all the rider's weight,
but when butt-burn sets in, there aren't a lot of alternate positions available.
The bike tracks great over a long haul. Its long rake and trail figures result
in a chassis that ignores rain grooves and goes straight.
Hacking a path through the urban jungle is the
bike's real forte. It loves to cruise Brando-like through town in a quietly
testicular way, and doesn't mind stopping at every intersection any more than a
dog minds sniffing every bush on its daily rounds. Volvo-ingested urbanites, who
wouldn't notice Team Lucky Strike practicing nude, seldom fail to worriedly
sideglance the Virago, while certain other denizens of the city frankly ogle it.
The laid-back riding position works as intended at low speeds, and the strong
off-idle power lets the bike burble away from stops with ease; you couldn't kill
the engine with a club unless it were a very large one. Clutch pull is light,
and short people have no reason not to like the Virago. A little more character
from the exhaust pipes would be nice, but Yamaha can't help that. Even God's
Harley has to satisfy the EPA.
Though the market share for Japanese customs has
dwindled in recent years, the demand shows no sign of vanishing and neither does
the Virago. It benefits from the same gradual refinement policy Yamaha so
successfully applies to the other veterans in its lineup—a policy that has kept
the Virago the most economical big V-twin on the market while making it the most
functional. If you subscribe to the theory that motorcyclists are modern cowboys
and bikes their horses, then this particular steed is ol' Paint. A little long
of tooth, perhaps, but an honest and reliable companion.
