By 2000, the 748 range was due
for an overhaul, and Ducati took the decision to expand the range at the
entry level. Consequently, three 748s were launched in late 1999. The base
748E was a budget, entry-level model, with cheaper chassis components and
the same engine as used in the previous 748 Biposto. The middle bike of the
range was the 748S, which used the older engine design but had uprated
wheels and suspension.
But the star of the 2000 748
lineup was undoubtedly the 748R. This racer-for-the-road incorporated a
number of changes to improve the 748's chances in World Supersport racing. A
new frame, borrowed from the 996 WSB machine, allowed the use of a new,
larger airbox. This in turn allowed an all-new fuel-injection setup, with
Formula One-style 'shower' fuel injectors mounted deep inside the airbox,
pointing straight into the massive 54mm (2.1in) throttle bodies.
Together with higher lift cams
and large valves, these changes transformed the performance of the 748
engine, boosting power to 79kW (106bhp). and giving increased potential for
power increases on racing machines.
The chassis was also radically
overhauled. New, lightweight Marchesini wheels reduced unsprung weight and
increased style. Fully adjustable Showa suspension front and rear is highly
specified, with a gold-coloured titanium-nitride coating on the fork
stanchions to reduce stiction and improve performance.

For 2001, the 748R received a
further update. The Showa suspension was replaced with race-spec Öhlins
forks and rear shock, and a lighter frame was fitted.
Detail engine refinements
improved drive and reliability and a carbon-fibre airbox added extra
stiffness to the lightweight frame.
The 748R riding experience is
sublime. Best kept for track riding, the feedback and response from the
chassis, together with the strong engine, makes riding the 748R one of the
purest sportsbike experiences available.
This bike was designed from the word
go to win Ducati its first World Supersport Championship, spurred on by the
previously unofficial World Series achieving championship status for 1999.
Ducati had already
won the Supersport World Series in 1997 with Paolo Casoli aboard a 748SP, and
intended to do it again in 2000, this time with Casoli aboard the RS version of
the 748, especially built for the mission (refer to the panel story on page 30
to see how close Ducati got).
The upside of this
single-minded determination to win is that to qualify for championship
contention, a minimum of 1000 homologation units must be made.
So Ducati developed
the 748RS racebike first, and then worried about building the road-going
homologation bike, essentially a more user-friendly version of the full-house
model. Enter the 748R.
Rain on
The specification list reads like a who's who of performance parts manufacturers
which, when combined with the R's minute dimensions and subsequent light weight,
add up to a true performance bike for the road - even if 748cc is traditionally
deemed small for a V-twin. It's difficult to convey just how small this bike is
unless you've seen it and sat on it. It's tiny!
And it definitely
felt that way when I climbed aboard for a day ride along the Great Ocean Road.
Having recently done a similar trip on the somewhat larger Luxo-tourers (see
Barge Wars page 44), I was pretty keen to cover the same roads on the 996R's
little sibling. But little did I know that the sun I started out with was to be
replaced with torrential rain by midday. And I mean torrential. Typical!
Also immediately
apparent once astride is the somewhat aggressive seating position. The single
seat unit actually points you downhill, helping to put your weight over the
front Marchesini, also affording an excellent view of the machine's individual
production number stamped on the adjustable triple clamp.
The traditional
needle and clock instruments, with anything but traditional green characters,
are easy to read, however the tacho curiously lacks a red-line. No matter, the
power tails off above 11,000 rpm, just before the rev-limiter, so no need to rev
any higher than that.
Race-spec
On the road, the upside-down Ohlins forks feel somewhat firm, as to be expected.
The faster I went though, the better the front worked, due to the increased
loads better suiting the forks design. The same applied to the rear 'piggy-back'
Ohlins monoshock.
With both ends
fully adjustable, the firm ride could be modified to some degree, though if you
were expecting a plush, marshmallow ride, you are probably part of the wrong
customer demographic.
The race-spec front
brakes, comprising Brembo four-piston calipers squeezing 320mm semi-floating
rotors via braided lines, were more than up to the task. Applying that
adjustable front lever hard in a straight line resulted in enough stopping power
to render the rear Brembo set-up superfluous. After all, what's the point of
applying the rear brake if the back end is in the air.
The feel through
the lever allowed me to brake confidently on suspect surfaces, also a function
of the Pirelli Dragon Corsa front tyre, a quality I really appreciated when a
storm turned the road I was travelling on into something resembling a muddy
lake.
Also assisting in
this unbridled confidence was the nature of the 748R's engine. Lacking the
lumpy, pulsing low-down delivery characteristics of the larger V-twins, the
'little' 748R tractered confidently through the conditions.
The Marelli EFI
also had a lot to do with this, allowing for the precise throttle control
required in these sort of conditions. There was very little of the on/off/on
throttle hesitation common to other fuel injection systems.
This also shone
through before the big wet set in, giving me the option of either sticking to
one gear and lazily rolling through, or playing boy racer and tapping away on
the sweet-shifting gear lever with the tacho needle hovering near the limiter.
Letting the revs
get too low, however, will see the engine misbehave a little. Remember though,
this bike is racer first, road-bike second.
It isn't a major
problem though, as the bike revs out so cleanly through the mid-range and
beyond, that it's a pleasure to ride it this way. Any vibes are quite low-key -
it really is a great road engine.
Initiation
But as I mentioned earlier, this bike is meant for the racetrack, and what a way
to sample Phillip Island for my first time ever.
And what a bike to
learn the track on. Any mistakes with line choice, brakes or throttle were
easily absorbed by the bike, as its limits were well beyond mine.
Honda Corner was
interesting as it requires braking from fifth gear speed to first gear, and
showed up a number of the bikes attributes. I just couldn't seem to brake late
enough. Before I knew it I was down to below the speed necessary, and in fact
had to release the brakes altogether a couple of times just to get to the
turn-in point.
Despite braking
later and later, the front Pirelli wasn't protesting too much, the bike was dead
in line, and downshifts didn't create any compression lock-ups. The bike was
mocking me.
Once at the turn-in
point, only small inputs were required to lay the bike over, where upon both
wheels would track exactly where I wanted. Even with the adjustable
triple-clamps in the 'standard' position (24.5 degrees), the steering was fast,
but not at the expense of stability.
The small
non-adjustable steering dampener may have had something to do with that, though
I suspect it was more the sweet set-up of the chassis.
The track is where
the firm settings at both ends came into their own. Dive under heavy braking was
well controlled, and the 748R felt balanced through all corners, fast or slow.
To tell the truth,
I hardly noticed the suspension action at all, a sign there was nothing untoward
going on.
Response from the
engine was instantaneous, which combined with the rear Dragon Corsa to give me
the confidence to drive hard out of every corner, before shifting up through
that sweet action box.
Boggy
beginnings
Which brings me to the one thing this bike makes hard for the rider, race
starts. The dry clutch made it difficult to get off the line cleanly, either
hoisting the front wheel or bogging down. In the bike's defence, I only had
three or four goes at it for fear of damaging the clutch, and I am sure practice
will get it better.
Truthfully, it was
very difficult to fault the 748R in terms of performance or finish. Small
touches such as the quick-release fairing fasteners and hydraulically operated
clutch just served to highlight Ducati's attention to detail.
And it's not as
though the company has rested on its laurels with the 2001 748R. A lighter
flywheel and crank, lighter pistons, revised gear selector drum and the same
Ohlins forks as found on the 996R now grace the '01 748R. The frame too is
similar to the 996R-s, although lighter in construction.
Just like the
exotic $50,000 996R, the 748R is as close to a racebike for the street as you
can currently buy. It's $6000 more expensive than the standard 748, but you get
a lot more than just the additional claimed nine horsepower.
In retrospect, the
storm I suffered on the Great Ocean Road was a blessing in disguise, showing
another side to a bike that has a well-deserved reputation as an out-and-out
sportsbike. It's a side that I was happy to see when piloting the $24,995 748R
contender through atrocious, twisty roads, and proof to me that it's worth every
cent.
