The Bulldog is a rather curious motorcycle, with a somewhat
confused identity. Styled like a naked, aggressive musclebike, which looks
like it could take on Ducati's Monster or Buell's X-l, the Bulldog actually
offers rather mediocre performance. Its exposed V-twin engine is borrowed
from the XVI100 Drag Star, and offers just 48kW (65bhp). Chassis-wise, a
tasteful steel-tube perimeter frame snakes around the top of the engine,
Rl-type front brakes are fitted, and the hunched fuel tank makes the
Italian-styled Bulldog look like a short, taut machine. It's attractive too,
with a neat flyscreen and high-quality detail finish. But again, the
performance is more akin to a cruiser than an aggressive musclebike.
Milan, Italy, 12 June 2002 -- Oh my, oh my, what a little teaser she was.
Just two years ago, a fresh and naked beauty ended up as a desktop
background on countless computer screens around the world and prompted grown
men (me included) to drool. Yep, that brutal MT01 concept Yamaha showed at
the Tokyo Show was one hell of a turn-on. But in life, fantasy and reality
do not often meet. The promise of a big-big-bore streetfighter, (or was it a
supermoto with the mother of all engines?) ended up splitting into two
different and somewhat diluted versions. Americans got their low & mean 1700
Road Warrior to play with, while Europe had to be content with a...mmm...
how to call it? A naked power standard? Urban retro cruiser? Big pseudo-trailie-on-acid?
Enter the BT1100 Bulldog.
So like many Yamahas before, the BT1100 Bulldog is a tool that resists
conventional definition. Yes, it does have Ducati Monster influences, some
traces of that sexy MT01 concept bike and maybe a pinch of Buell poise
thrown in, yet surprisingly, at the end of the day the result is so original
that it earns the privilege of founding a new niche. Original-schmoriginal,
the BT1100 is also a fine example of progressive motorcycle design, from its
stubby proportions and bold shapes down to the abundance of amazing fine
details. Countless approving nods from Milanese motorcyclists showed that at
least on the styling front, Yamaha's designers got it more than right.
Mechanically speaking, it's a bit of a mixed bag. If that motor
looks familiar, that's because it's been around for 20 years now, having
powered the first ever Japanese V-twins, the Viragos 750 & 920 (and later
the 1100 Drag-Star). The air-cooled, two-valve-per-cylinder unit has never
won any horsepower contests, so any expectations you should have for easy
burnouts on the twist of the throttle would better be shelved. The frame, on
the other hand, is one bold and massive piece and holds much promise for
rigidity and sporting prowess while enhancing the bike's looks with its
daring mid-tank plunge. Further strengthening that sporty image are those R1
brakes, beefy right-way-up forks and a 170-section rear tire. And then you
notice it's got a nerdy shaft drive and handlebar risers. Confused? So was
I.
Things clarify rather quickly upon sitting on the bike and moving on. Any
fears of a tough and hard-edged MMI (man-machine-interface) dispel as your
butt and feet meet the soft surfaces of the seat and footpegs. Guiding
position is true dual-purpose, loads of leg room, high and erect, with the
bars feeling at first a tad too close and wrongly angled. A little fumbling
with the choke lever under the tank and we have the engine running. There is
a deeper rumble coming from the pipes than on the Drag Star, but throttle
response already hints at a very mild response. And indeed, after a few
stoplights the last hopes that there would be a mean streetfighter hidden in
there somewhere, disappear. What a pussycat! Yamaha claims to have raised
the peak output of the 1100 mill by three ponies, but with 65 claimed hp,
the engine is a real softie. What does make riding the Bulldog a bit more
interesting enginewise is that the peak torque point has been shifted from a
lowly 2500 rpm in the Drag Star, to some 4500 in the BT1100. So instead of
having an engine that pulls from zero revs and runs out of puff by the time
the tacho needle crosses the two thirds point; the BT's engine is much more
of a revvier and doesn't mind hitting the 7000 rpm rev limiter every now and
then. In the lower half of the range it's a nice plodder with the power
climbing in linear fashion from 3000 rpm and up.
With its powerful brakes, you can rest assured the Bulldogs brakes are
far stronger than its bite.
Although disappointing at first, the super friendly power grows on you as
you clock more and more urban riding miles. The engine is a real doddle to
use, and it's helped by the cycle side of the equation, which feels really
at home in the city. The erect riding position works superbly and allows for
easy scanning of the surroundings without any neck breaking contortions
needed, an important virtue in the world's fashion capital, where model
types seem to grow on trees. On the countless stone paved streets of Milano,
intersected by streetcar rails, the soft fork filters out most of the white
noise while the progressive-linked monoshock is a bit less accommodating on
bigger bumps. Steering-wise, the wide handlebars produce instant steering
response in tight situations and hide well the considerable mass of this
well-trained Bulldog. Time to hit the highways and the canyon roads.
With a fully upright riding position and a tiny bikini fairing for wind
protection, cruising speed depends mainly on your will to fight the air
pressure. The engine is capable of propelling the Bulldog to some 110 mph,
but eventually 90 is a far more reasonable proposition. The limited amount
of horses in the stable means that quick overtaking requires a downshift or
two, but as long as you're not trying to compete with any squids out there,
the BT gets the job done without any perceivable vibration.
On long freeway stints, the all-too-accommodating saddle becomes
more of a pain in the rear. As it often happens these days, it's another
case of a too-sculpted seat that keeps you pinned to just one position.
Borrowing a term used by a MO reader, if your "lard factor" is above
average, there's a good chance that things are going to be a bit cramped in
the gender-defining zone.
Cramped or not, the Bulldog comes into its own again when the going gets
twisty. There, the mixture of great stability and high grip provided by
those huge tires, the stiff frame and the ample leverage of the wide bars
works really nice, enabling a good rider to maintain an entertaining pace.
Just like a good adventure tourer, the Bulldog supplies clean fun in the
twisties, but it's no supermoto.
The 506 pounds Yamaha cites as the bike's dry weight, and the slightly
underdamped fork eventually start to be felt when the pace picks up. Just as
well, ground clearance is not one of the BT's main virtues, although by now
it starts to be clear that on the BT1100, if you're pushing that hard, you
are certainly calling the wrong number. In the braking department, the
BT1100 doesn't need any excuses. It's R1 derived brakes need no introduction
and supply ample power and feel in any situation. The rear brake, though, is
almost too potent and locks too easily, not the best thing if you are a
beginner.
Beginner? Who said beginner? Here at MO we are all a bunch of
hairy- arsed bikers, aren't we? Must have been my unconscious playing games.
After a few days of riding, the fact that the BT is one docile ride that
could be a stepping stone for anybody climbing up the capacity ladder cannot
be denied, and that in itself is quite refreshing. Save for Suzuki's SV650,
there hasn't been a new, true beginner's mount in quite a long time,
certainly not an 1100cc model.
Then we have that design issue. Just like in a cruiser, where performance
is secondary to looks (or at least it used to be...), the BT1100 provides a
hot conversation topic whenever it is parked in a bike-choked lot. Yamaha is
the only Japanese company using the services of an external design office
(GK Design) and that reflects on many of its models. The daring and
courageous shapes of the Bulldog might have never been born within the
confines of corporate design.
Above all, the Bulldog is one hell of an urban tool. I had a hard
time trying to recall a bike that was so much fun to just hop on and go for
those little errands--to my lover's or to get (cigarette!) rolling papers
from the corner shop. Weigh in other factors like the low maintenance drive
shaft and engine and the BT1100 starts making sense as groovy everyday
transportation, beginner rider or not. Last but not least is the price
issue. In Europe, the BT is sold in the same price bracket as the H-D
Sportster, Triumph Bonneville and Ducati Monster 750. Against that sort of
character-laden opposition, the BT1100 is on level battling ground. Will its
quirky character appeal to the American riding public? That's the big
question. At the moment Yamaha thinks not.
