Road Test
The actual weight difference is not great; 335
lbs. for the Tiger as compared to 363 for the top-of-the-line Bonneville. But
the compactness of the smaller bike gives it a feeling of agility usually
associated with 250 or 350cc machines.
The Tiger's wheelbase is two important inches
shorter than that of the larger Triumph. The short handlebars are another factor
favoring the bike's maneuverability. They are raked back about 3" for maximum
rider control.
Another factor of great importance is the
excellent rider position afforded by the Tiger; Even a short man can reach the
ground with both feet and on the dirt the rider has great freedom of movement to
lean forward or to the side, still maintaining good balance, even at speed.
Exhaust pipes are swept around the engine to the left side where they are
smoothly joined into a single pipe which is tucked neatly alongside the engine.
A safety precaution which might have been added is a heat shield, although it is
unlikely that a rider could get burned from the pipe in this position. Footpegs
are high. They are of the non-folding type.
An impressive feature of this machine is the more
than ample ground clearance, achieved via several methods; for one thing, there
is no centerstand, only a sidestand (which is lengthened by necessity to
compensate for the added ground clearance). The front tire (by Dunlop) is a
large 3.25" x 19" and the rear sports 4.00" x 18" rubber. The result is nearly 9
inches of space beneath the center of the machine; plenty of leeway for big
rocks and deep ruts, the kind of terrain for which the Tiger is intended.
The other type of riding that suits this bike is
ordinary street cruising. We found either type pleasurable on the T100SC. There
is a noticeable difference between this bike and the more powerful 650 models in
the Triumph line, not only in acceleration, but in smoothness of ride. The
Bonneville, for example, gives less vibration and generally a more solid feeling
in high speed freeway type cruising. One contributing factor might be the fact
that the 500cc model does not feature the rubber-mounted handlebars found on its
big brother. And, of course, the 500 requires more rpm's to develop its power.
Triumph claims 38 horses at 7,000 rpm compared to 50 horses at 6500 for the
street Bonneville, a substantial difference. But the Tiger is capable of feats
that the larger Bonneville could not safely attempt. We felt right at home with
the T100SC off the road on trails that are usually exclusive to all but
lightweights. The torque is there for the steepest inclines and the suspension
will iron out the choppiest terrain as well as any off-the-road bike we have
tested. The horsepower creates a tendency for the bike to rear back on its hind
wheel but this is easily controllable by the rider shifting his weight and,
working the throttle.
As is always the case with combination
street-dirt machines, there are some areas of compromise; the same tires that
perform well on the road lack proper traction for trail or desert. And road
gearing is a compromise off the road, the rear sprocket having 46 teeth. Triumph
has eliminated one normally troublesome area of compromise with a readily
detachable headlight. Five minutes is all the time it takes to yank the unit
from the bike in preparation for a back country jaunt. On the whole, there are
few, if any, improvements that could be practically applied to this bike to make
it more ideally suited to its dual purposes. Prospective owners of the Tiger
should be aware that this machine requires a long break-in period. The engine is
set up unusually tight and even at 1,000 miles performance will not be at its
best. The first 300-400 miles will, in fact, be somewhat disappointing to the
rider graduating from a well broken-in 250. It will be well to heed the advice
of Triumph dealers who will tell you to be patient with the 500 until ample
mileage is accumulated. Then speeds of 100-plus may be expected.
Some features worthy of comment are as follows:
STARTING. 9:1 compression is quite a lot and the
Tiger requires a healthy kick but usually starts on the first kick. The lever,
located on the right-hand side is slightly on the short side, meaning more
muscle needed. The single Amal carb is equipped with a tickler to assist in
starting.
STOPPING. No ignition switch is provided on the
battery-less magneto-equipped machine. A kill button is located on the left of
the bars. In fact, no locking device of any kind is to be found on this machine;
a definite drawback in our opinion.
LIGHTING. The quickly detachable headlight is
unique also in that it contains its own dimmer switch, mounted to the right of
the on-off switch. Taillight is large, contributes to bike's safety on the
street.
FINISH. Typically British, the Tiger is
immaculately painted (Burnished Gold tank, black trim). Chrome and polished
alloy parts are strictly top quality.
BRAKES. Front braking is via full-width alloy
hub; rear brake is not full width. Both have 7" diameter braking surface.
Stopping power rates excellent.
SHIFTING. Gearbox operates extremely smooth.
Ratios enable good flexibility on or off the road.
The Tiger T100SC is an ideal motorcycle in many
respects,
especially for the enthusiast who uses his bike
for various types of riding, and who has the experience necessary to handle a
really powerful off-the-road machine.
