748/916/955/996 and Monsters
Ducati offers the ultimate sportbike in more ways then one.
The Ducati brand has won more World Superbike Championships
than any other manufacturer, with Ducati's current production
based 916/955/996 variant having won more World Superbike Championships
than any other model of sportbike. And today it still remains
one of the most competive winning racebikes since its introdution
some 7 years ago. And Ducati is the only sportbike manufacturer
to offers to the public a complete catalog of all the factory
performance parts and upgrades need to turn your bike into the
ultimate canyon blaster or National Championship race winner.
No other sportbike manufacturer can make this claim.
All the
parts you need to up grade the performance of your 916/955/996
and Monster are contained in the Ducati Performance Superbike
Accessories and Kit Catalog, avaialble from your Ducari
dealer for $6 or download it online at the
Ducati.com website. You'll find everything in their catalog
from engine performance parts including piston and cam kits,
to slip-on race silencers and complete racing exhaust system
with matching E-prom computer chips, to magnesium racing wheels,
carbon fiber body components, amd racing brakes. I do not not
recommend running other aftermarket brand products on your Ducati,
both because they probably won't perform as well and because
it will lessen the estetic value of such a purist's machine.
The few exceptions to this rule might include the rear shoche
brake calipers/rotors where there are highly competitive options
available.
My own
personal favorite sportbike bike has been a first year '94 base
model Ducati 916 Strada which I quickly modified and upgraded
with the help of my friends including Ederaldo Farracci at Fast
by Ferracci on the East Coast, and at Pro Italia here in Los
Angeles where I live. It soon exceeded SP specifications and
for the past 6 years has served as my Sunday morning excape
from reality on the twisty canyon roads up through the Manta
Monica Mountains to the Rock Store and back. It has more power
than I can ever put to use on the tight canyons, but I burned
out on the Southern California racetracks back in the '80s.
As of this writing I am awaiting the delivery next month of
my new 2001 model limited edition 996R Testa Stretta.This new
homologation special in stock form won't force my cherished
916 into retirement, but it's the starting platform for s current
Factory Team Corse Superbike with the help of the 996RS Parts
Book.
Where
to make changes? Or how to improve upon perfection? This depends
on your riding skill level and where you feel your Ducati
needs to be improved. And the size of your wallet since
Ducati parts, like the bikes, aren't cheap. For half the
Ducati streetbike riders I talk to the stock bike already
exceeds their riding ability or needs, and a few carbon
fiber body parts or a slip-on silencer kit is all they
need to personalize their bike.
Two Books you need:
Ducati 4-Valve V-Twins availabe from our
Book
Store Covers the history and design of the 916-996
Production and race models.
Ducati Performance Superbike Accessories
and Kit Catalog available from your Ducari dealer
for $6 or download it for free online at the
Ducati.com website.
You'll
find everything in here from engine performance parts
including piston and cam kits, to slip-on race silencers
and complete racing exhaust system with matching EPROM
computer chips, to magnesium racing wheels, carbon fiber
body components, brakes.
Less
Weight Equals Horsepower & Handling
Most people think the first step to improving performance
is bolting on a tuned exhaust system, and to some degree it
is. But just as much or more of any performance gain comes
from the bike's improved power-to-weight ratio from the lighter
exhaust system, than from
any horsepower gain the engine will pick up on todays's modern
production sportbikes.
Reducing wight
has a three-fold advantage in that it not only improves the
bike's power to weight ratio for quicker acceleration, but
braking distance is reduced just as proportionally, and handling
is improved and quickened up as well. So even before spending
money on an exhaust system, you might want to consider a set
of lightweight magnesium racing wheels. Ducati offers a number
of choices in their Performance Parts Catalog. On my early
model 916 replacing the stock aluminum Japanese wheels with
magnesium Marvics saved 10 lbs at the back wheel and 6 lbs.
at the front. At a cost of about $600 per wheel your looking
at a weight savings of around $60 per pound, which is how
I like to figure out the value of a replacement performance
part. (So go figure that trick set of machined foot peg
brackets that cost $400 and only saved 6 ozs. is pretty much
a waste of money. As are most titanium fastners)
Start
with the Suspension My first year 1994 model 916 came with Showa
suspension.
And quite susprisingly the front forks worked beautifully after
fine tuning the adjustable damping and preload settings. Pay
a visit to our Suspension Tuning
page to see how it's done.
The rear shock was
another matter. I've never met a Japanese production based rear
shock I've ever liked, or that could be adjusted or modified
to work well. They handle like shit and Ducati only puts them
there to hold up the back end of their base model bikes during
shipping to the dealer. It's now up to you to bite the bullet
and spend the bucks it takes to get a good Ohlins shock as found
as original equipment on the higher priced Ducati models, or
another brand shock from one of the highly respected racing
shock companies like Fox Racing, White Power or Penske.
Does
it Stop?
When I first began riding my early '94 model 916 Strada hard
on the mountain canyon roads around Los Angeles I quickly began
feeling the front brakes fading and requiring a 4-finger death
grip to keep the bike from catapulting off into an abyss. The
culprit was the high chrome content in the stock front brake
rotors used to prevent unslightly rust on pretty street bikes.
Unfortunately this high Cr content has a poor coefficient of
friction and does not provide the best stopping power and fade
resistance. I made the switch to the Braking brand of brake
steel floating brake rotors and found a great improvement in
stopping power. Ducati now offers similar high steel content
beake rotors in their Performance Accessories Catalog.
Just so you know,
the higher performance 916 SP (Sport Production) model introduced
in 1995 and the later 996 SPS models come standard with cast
iron full floating front brake rotors.
Engine
Performance
Now, when it comes time to consider improving engine performance
you need to plan ahead. If you only want a small power improvement
with the racey good looks of an Aluminum, Carbon Fiber or Titanium
Silencer and the sound that comes with it, then just get one
of the Ducati Performance bolt-on kits. The kits come complete
with remaped computer EPRPM chips to richen up the fuel injection
as needed.
However, if you
know you'll be wanting more power now, or sometime down the
road with a set of Ducati higher compression pistons and maybe
a cam kit, then go for the full race Termignoni Exhaust System
from the Performance Catalog. It
will set you back about $1,500. But it's worth it both in the
weight savings, the potential for additional engine modifications,
and the addaded value of upgrading your base 916 or 996 model
towards "SP" and "SPS" model specifications.
On my bike I opted
for the higher compression race piston kit and cams, and the
EPROM chip was remapped at Pro Italia to match. So now it's
pumpin' out around 140 hp @ 11,000 rpm, up from the stock 109
at 9,000. It still runs on pump gas and has a better powerband
than any Oriental inline 4, but there was a tradeoff. Where
before I'd just short shift the bike and never have rev it over
7,000 -all that bottom end torque was fantastic in the tight
canyons1 The modified motor has lost some of that beautiful
low end grunt and does needs to be shifted a little more often
(but it still pulls a lot better than an R1 Yamaha). But now,
come 7 grand and it's on the pipe and putting out way more power
than anyone can handle on a public road. I can't use all that
power off a race track, but it's fun to know it's there. So
that's the choice you'll have to make when it comes to modifying
the engine. A pipe is all you really need for the street.
