Headline: Say what you will about the fluted sidepanels, the
woofie pipes, the wheelbase that groans like the span of a
suspension bridge. Cast your eyes across Honda’s new Magna
700: the shape of a Sole Survivor.
In
the Lounge-and-lunge world of power cruisers, Honda’s new
Magna may not be the lowest bike around, but it is the
longest. Parked on its sidestand, the Magna hangs just above
the height of a man’s knee, a lanky peninsula of rubber and
chrome and painted metal jutting out into the street -
stretching 66 inches between axles.
With its tail section low and
flat, swinging aboard the Magna feels like clearing the
Molehill Hurdles. You fall inside the saddle, confront the
asymmetrical clocks, needles tacked onto the gray crinkles
finish of the dash under glass faces. A flick of the starter
button stirs the water-cooled V-four to life instantly,
inevitably.
This marvelous engine - smooth,
crisp, compact - delivers a broad, flat band of power as
distinctive as the signature of its sound. Five years ago
the Magna took the gattling-gun thud of the V-four to
American streets, spawning a tide of Maduras, V-Maxes and
other Magnas...all history in 1987. Only the mid-sized VF
custom - the first, perhaps the last and arguably the best -
remains. The Magna 700, even in startling new clothes,
captures the essence of a genre in passing: the
V-four-powered performance cruiser.
The success of that first Magna
assured the breed its curious, paradoxical appeal. Into a
steel-tube cradle frame drawn as long, lean and elemental as
a chopper/dragbike was bolted a power train as avant-garde
as tomorrow: a 90-degree V-four with four overhead
camshafts, 16 valves, water-cooling, hydraulic clutch, six
speeds and shaft drive.
With the power cruiser’s
antipathy of shapes and technologies, success for early
brute bikes was measured in the more or less peaceful
reconciliation of warring elements. The mating of a
traditional-look chassis with a potent engine created new
challenges for designers - like steering a fat back wheel
with a skinny front and still preventing the bike from
leaping of the road when a turn appeared or the throttle was
applied.
Riders, drawn by the harmony of
High Style and High Tech, hopped aboard to discover that,
though not as brutal as the big-bore cruisers that would
soon follow or as versatile as the standard bikes which
would all but disappear, the middleweight Magna worked quite
well.
The following year, marketing
pressure for the Magna bled off into alternate niches as
Honda introduced its Interceptor, Shadow twin and the 1100
Magna. In 1984, tariff-mandated de-stroking dropped a
claimed three horsepower off the top, but added 500 rpm to
the VF700’s redline. The Magna’s second year of production
as a 700 brought restyling touches - a longer wheelbase,
lower seat, larger-diameter fork tubes, different wheels.
Still the Magna remained essentially unchanged from the
original VF cruiser form: longer and leaner, with the Early
Industrial density of the V-four engine.
The Magna’s mechanicals in many
ways created the very problems Honda engineers took such
clear delight in slating for the Corporate Solution. Take,
for instance, the gas tank(s): Since an airbox occupied the
traditional fuel-cell space, the VF acquired a supplementary
tank beneath its seat. An electric pump trickled the. fuel
uphill to the bank of carburetors nestled in the crotch of
the engine’s Vee. A warning light indicated low fuel, but
the VF offered no reserve.
Getting the seat height down into
the lizard zone meant running the frame rails literally
through the rear cam cover, which was split for clearance.
With space at a premium, the option of monoshock linkage was
clearly out: dual shocks were fitted. The Magna’s tool kit
got stuffed into a thin tray behind the sissy bar.
Solutions, yes, but achieved at the cost of both complexity
and inconvenience.
With the new Magna, Honda has
used redesign as an opportunity to address the interests of
economy and simplicity as well as high style. Despite a
larger-capacity airbox, the 700 holds a full 3.4 gallons of
fuel in a single cell behind the steering neck - no pump, no
warning light, and a petcock that turns on 30 miles of
reserve. Beneath the louvered sidepanels one finds ample
space for essentials - a coolant reserve tank on the right,
a plastic pan for tools and modest knick-knacks on the left.
At the Magna’s core, the V-four
has undergone changes that affect the engine both
technically and visually. Gas station mechanics will rattle
their ratchets in disbelief at the suggestion that this
motorcycle is only a 700. No more blacked-out cases here -
the new Vee, lounging like some chromium colossus in the
stretched and lowered hammock of its frame, looks massive
enough to rise and dine on 1100s.
Riders
will feel much the same when they twist the Magna’s
large-grip throttle for the first time. The packed-down
punch of the VF engine is crisp, with instantaneous response
and liter-bike strength until the revs climb to 7000 or so
and the power levels out. Honda claims 80 horsepower at 9500
rpm from this engine, the three horsepower lost to
destroking now stacked on top of a stronger mid-range.
In fact, the new 700 behaves much
like the original, full-sized 750C, also factory-rated at 80
horsepower. (The standard-oriented VF750S Sabre, strapped to
the Kerker dyno in 1982, made 65 horsepower at 10.000 rpm at
the rear wheel). At the drag strip, our ‘87 VF ran through
the quarter mile a tick quicker - 12.25 seconds at 107.95
mph - than the first Magna, four - tenths and a mile per
hour up on the VF700C tested in ‘84.
What gave the new Magna its shot
in the arm? Certainly not the engine’s basic pieces: crank,
pistons, rods, transmission and the block of 32mm Keihin
constant-velocity carburetors - two sidedraft, two downdraft
- are all unchanged. This engines greater strength appears
courtesy of its four-valve heads. All ports have been
reshaped, the inlet side tapering to intake valves grown one
millimeter from last year’s poppets, now 37mm. Exhaust
valves remain at 23mm. The Magna continues to use
screw-and-locknut adjusters on forked rockers for setting
valve lash.
Inside the heads, new cams with
0.7mm less lift, their timing juggled for less overlap,
build power in the midrange. Honda claims the new cams are
primarily responsible for notching the VF’s redline down 500
rpm to 10,000, again like the original Magna. Reshaped
combustion chambers drop compression from 10.5 to 10.2:1,
and our Magna performed without a trace of ping on regular
unleaded fuel.
Other changes include
installation of Honda’s new ignition system, first seen on
last year’s VFR750, which feeds a digitized signal to the
black box computer for plotting ignition timing curves. The
new system, Honda claims. is less affected by both
manufacturing tolerances and the occasional magnetic
interference of extreme cold weather. A 12AH battery has
been substituted for the previous 14AH unit, and the engine
has also sprouted a pair of crinkle-finish black metal
shells on either side, just aft of the radiator. The pod on
the right contains the cooling system’s thermostat housing
and sender for the dash-mounted temperature warning light -
no gauge on this VF; the left side, empty on our Magna, will
hold the evaporative emissions hardware for California-only
models.
The Magna’s engine remains as
jewel-like as ever. It starts, hot or cold, with an ease and
surety that has your thumb just briefly touching, rather
than holding down, the starter button. You listen for the
pop of ignition with no more anticipation than you would in
flicking a light switch. Carburetion is dead on throughout
the rev range - no flat spots or sputters and, though a
slight popping comes through the pipes on trailing throttle,
the crispness of the Magna’s response and the broad, flat
curve of its powerband produce excellent roll-on
performance. In third gear, under full-throttle acceleration
from 45 to 75 miles per hour, the Magna is a match for most
750 sport bikes, and the four-pot VF simply clobbers the
Shadow V-twin. Tall cogs compromise the Magna’s acceleration
in the upper two gears, but the bike still pulls with
authority, and cruises - gone is the “overdrive” indicator
light - at about 4300 in sixth gear.
At highway speeds, as in city
traffic, the V-four engine is a personable and willing
companion, smooth to 6000 rpm or so - good for 80 plus in
top gear - where vibration begins a light strum through pegs
and seat, increasing in intensity to 9000 rpm where it
submerges again into stillness. Shifting is positive and
precise, and the Magna’s clutch, though slightly grabby,
with a narrow engagement band, is strong and tractable.
Without adjusters, however, the hydraulic clutch and front
brake lever are a stretch for fingers reaching out from
milwaukee-style grips.
During brick cruising, the silky
smoothness of the engine’s upper register can have lead-wristed
riders in frequent contact with the Magna’s two-stage rev
limiter, a system also installed on Honda’s new Hurricanes.
When 11,000 rpm registers on the VF’s electronic tach, the
computer automatically cuts ignition to the front cylinder
bank and retards the rear. At 14,000 rpm, all spark ceases.
Even pressed solidly against the first stage of the rev
limiter, however, the Magna retains its glassy texture, more
remarkable still when one considers that this Magna’s
engine, unlike previous VF’s, is solid mounted in the frame.
On the highway, the sound from
the Magna’s exhaust system disappears into the wind blast.
At trolling speeds, the quartet of pipes produces a solid
staccato drum. One staffer disliked this beat, and felt it
amplified by the upswept pipes which directed the noise up
inside his fullface helmet. Others liked the sound. These
pipes are loud, certainly, but the engine itself is such a
silent mechanism (the generator cover has been thickened
this year to further reduce sound escaping from the engine
block) that R&D, in the face of the 80-decibel limit, can
devote itself to developing the throaty V-four roar rather
than covering up extraneous noise.
The VF’s exhaust layout was
designed to accentuate the multi-cylinder look and
distinguish the Magna from a host of V-twin style cruisers.
And, unlike many motorcycles that conceal massive collector
boxes beneath their engine cases, the Magna is a true
four-into-four system with narrow-gauge cross-over pipes
joining the tubes running from front-to-rear and
side-to-side. With ample clearance, the absence of a center
stand must be the result of economic rather than engineering
considerations.
Economic forces, and the
challenge to bring a new model in with a price tag only $100
higher than last year’s VF, dictated much of the Magna’s
form. The 700’s tubular steel frame, for example, is
basically unchanged. Two tubes swing back from the steering
neck, then angle down to triangulate with the swing-arm
pivot and shock upper mount. As with the original Magna, the
left downtube, which also serves as a channel for coolant,
unbolts, providing access to the engine bay.
The big change comes in at the
steering neck. The Magna’s front end has been kicked out
five more degrees from vertical than previous VF’s. This
700’s rake stands at 35 degrees, with a full six inches of
trail. The Shadow 700 has slightly longer trail, but rarely
have we seen such figures, even from full-on style cruisers.
It is this radical steering geometry, in combination with a
swing arm elongated 1.2 inches, that stretches the Magna’s
wheelbase almost half a foot over last year’s 700, to 66
inches.
The Magna’s new fork illustrates
Honda’s approach to the market economics of ’87: Thicker
39mm tubes stroke a long 6.1 inches, but the air caps and
TRAK anti-dive fitted to last year’s Magna didn’t make the
new-model cut. This year, with slightly stiffer springs but
softer damping rates, the Magna’s front end does nose dive
under hard braking, and we miss the opportunity to tune fork
preload to changing road and riding conditions.
Nevertheless, the fork offers an adequate compromise for
most roads and riders.
The Magna’s rear end is more
problematic. With only 4.0 inches of rear-wheel movement to
work with (up 0.1 inch over last year), engineers gave the
Magna’s twin VHD shocks extremely stiff springs to control
shaft effect and prevent bottoming over bumps. Five-ramp
collars permit preload adjustment, but position one provided
best even for two-up riding. Solo the Magna’s suspension
stayed unduly harsh.
The
new Magna rides on resized wheels: Honda tossed the 18-inch
front spinner from last year’s VF in favor of a 19-incher;
the thinner 2.15 rim holds a 100/90 Dunlop. The Magna’s back
wheel follows the prevailing trend toward disc wheels - a
15-inch solid casting holds a massive 150/80 tubeless Dunlop
tire;a spun aluminum cover plate press-fits onto the wheel’s
left side.
Those expecting its raked-out
steering geometry and gargantuan wheelbase to turn the Magna
into a freight-train handler will be pleasantly suprised by
its versatility and surefootedness. The sheer length of its
wheelbase gives the VF unshakable stability at speed, and in
tight spaces the Magna’s steering stays light and linear,
with no tendency to flop. Heavy steering loads from fast
turns will cause the front end to flex despite the Magna’s
steel front fender and light-gauge brace. The Dunlop tires,
impervious to freeway rain grooves, give good grip. The
single-disc front brake, though somewhat high effort, is
predictable and strong, hauling the VF to a stop from 60
miles per hour in a short 125 feet.. The drum rear provides
even, controllable stopping power.
Previously, a jackhammer shaft
reaction, intractable suspension and bucking-horse handling
were all part and parcel of the power-cruiser experience,
with potent engines routinely overwhelming their chassis
while the poor rider hung on, white knuckled, for dear life.
With the Magna we confront a chassis that feels firmly in
control of the engine driving it: a motorcycle long but
fairly light (the Magna weighs 530 pounds wet, only a pound
heavier than last year’s VF) can strike a balance at higher
levels of both stability and agility, with light steering,
quick braking and a controlled shaft reaction.
The Magna offers plenty of
opportunity for roomy ergonomics too, and the relationship
of the Magna’s seat, footpegs and handlebar (identical to
that of the old CX650 Custom) received high marks from the
Cycle staff. Complaints centered around the VF’s two-piece
saddle. The front section gives good support, but the seats
deep contours locate the rider in a position from which he
can shift around only temporarily and with difficulty.
Passengers are not so well served
by the Magna’s removable rear-section seat. Positioned a
full five inched higher than the pilot, the Magna’s second
rider feels top-heavy, a sensation passed on full-strength
to the first. With pegs high and forward due to the upswept
pipes and only an over-tight grab strap for security, the
Magna’s narrow, hard pillion becomes a precarious perch.
Design for touring bikes has taken great strides to
accommodate the passenger in comfort - sometimes at the
expense of the rider - and sport bikes strike an equality of
comfort (or lack thereof) for both riders. But in Magnaland,
says Honda, you passenger had better have quick reflexes,
provide his/her own padding and be devoted to the rider or
the sport.
Stylewise, the Magna is, of
course, filled with bits of greater or lesser fashion
statement. The flaring pipes, with nerf bars for heels and
kneecaps, draw the eye from the massive disc wheel forward
to the hump of the seat. The plastic, three piece chin
cowling frames the engine at its base; yellow, pink-capped
plug wires punctuate the cylinder heads.
Textures
invade uncommon places in the Magna - the instruments, seat
covers, handgrips, master cylinders. There are clever
subtleties - the welded, three-piece handlebar is
Harley-thick where the eye can see, then tapers for fitment
of standard-sized controls - and there are florid
flourishes, particularly the VF’s louvered sidepanels,
looking as if some wild flame paint scheme had imbedded
itself into the bodywork. Sometimes the Magna’s interweave
of textures gets cockeyed, with a gray-crinkle instrument
nacelle butting straight up into the black-crinkle finish of
the upper triple clamp. Regardless of the consistency of the
Magna’s styling, finish is excellent throughout.
Honda’s new Magna is as much a
new model with a new look as it is a telling corporate
statement at a time when the lineup of street machines from
the world’s biggest motorcycle manufacturer has shrunk to 10
models from 25 the year the Magna was first introduced. The
quiet, even competence with which the Magna works testifies
not only to the competence of Honda’s engineers in
incorporating the demands of the Styling Department, but
also to the success of the Magna’s new interpretation of
power cruising. In form and function, the Magna fits Honda’s
new, leaner philosophy of producing “back-to-basics,
leading-edge” machines; an intriguing exercise, more
stylish, more functional - and only a pittance costlier than
what went before.
