Alternatives to the genuine Ducati parts |
|
| Here
is a list of non-standard parts which have been suggested in good
faith as alternatives to the genuine Ducati parts, which can be scarce,
expensive, and some may be obsolete. Some information is only hearsay,
so I cannot guarantee that the suggested part is actually going to
fit. It is important to note that these suggestions have not been
approved by anyone, certainly not the Ducati Factory who would presumably
prohibit such fitment, void your warranty, and would possibly ban
you from entry to their museum if they were to find out. If anyone
decides to use non-standard components on their own bike it is of
course entirely at their own risk in view of the lack of guarantees
or assurances. If in doubt, seek the guidance of a qualified motorcycle
engineer regarding the changes you are considering. The mentioning
of any manufacturers should not be interpreted as an endorsement.
Many of the parts listed are from foreign vehicles and while they
may only be obtained from overseas, chances are that they may be easier
to obtain (and a hell of a lot cheaper) than original Ducati parts. Good luck!

Filters, air, oil and fuel |
|
| The
air filter for the 1992-98 900ss/851/888 is the same as fitted to
a Porsche 924. Dimensions are: 211 x 211 x 57. Purflex A515 (K &
N equivalent: 33-2003, Mann-Hummel filter part number P12210). Fuel filters: BMW K100RS part number: 13 32 1 461 265 (8mm) or 16142325859, Purolator F20011, AC GF61, Fram G2, Motorcraft FG-2, Wix 33032, CarQuest E2036 (mid-80's Ford Ranger. Fram part number G2). For the 916: Mahle KL 24/1, approximately 10-15 mm longer than the stock item, it has a 50mm diameter. The 1994 750SS has a FIAAM FT 4648 fuel filter fitted as standard,
here are some equivalents; A.L. ALG-6/8; Lautrette ELE1990; Chamption
L101; Purolator F57608; Ryco/G.U.D MF-1; Fram G 12-1; Tecnocar B 7;
GIF ES 77; UFI 31.001.00 Before using any of the above please be aware, early 650 Cagivas with
Ducati engines sometimes do not accept the 2CV car filter, the threads
differ. In this instance you will probably find that the following
3/4" UNF thread) will fit; Oil filters for bevel-twins: made by Meiwa for Kawasaki KLR250 &
Z250 (Kawasaki part no. 16099-004 = Champion X310 and Fram CH6070)
FBN OL1.01403. GT Replacement Air Filters - 0615.27. 275 * FIAAM FL 6179 * FIAT Part # 4110530 * RYCO A134 The fuel vent check valve for the 900ss (and others, possibly, which Ducati sells for $90 or so) can be sourced from a 2008 Kawasaki KLX450R and can be purchased new from Bikebandit.com for $11. It is plastic, not aluminum, but is the same shape and size, and is a nice dark grey

Brakes & Wheels |
|
| Recent
model 900 SS bikes have the same size front brake disc rotors (320mm)
as the Yamaha XJ1200, FZR1000 Exup and Genesis, YZF1000, FZR 750 Genesis,
SZR 660 and TZR 250 but check that the Yamaha carriers have the same
offset as the Ducati carriers. Ducati 907ie Brakes, ZDM906PI2, 900SS Bj. 88-90, ZDM906SC, Moto Guzzi
1000 Daytona Type KL. Grimeca 180 mm double-sided front drum brake from the early Benelli
250 2C (or equivalent Moto Guzzi 250) is the same as the later Ducati
singles. The lugs on the fork where the torque arms engage appear
to be identical to those on the early Ducati forks (the one with metal
gaiters of the MK3 and the one with rubber gaiters of the SCR). Since
the bolts that hold the mudguard are very small (6 mm) the torque
arms embrace the aluminium lug behind the bolt and are kept in place
by the mudguard's lugs. WHEEL BEARINGS - for 18 inch Borranis and FPS alloy mags BRAKE PADS for F08: (Brembo) D=07.2256.30

Carburettors and fuel system |
|
Parts
for Mikuni 38 mm constant pressure carburettors mounted on current
Ducati models such as the Monster or Supersport are also available
at Yamaha dealers because the TDM 850 uses the same. Rubber inlet
"pipes" for the carb to manifold junction on the 750F1 or
36 mm 89 900 and Paso with Webber carburetor, parts and overhaul kits are
available from auto shops, also high velocity air filters to replace
the standard air boxes well as the small filter to fit the crankcase
breather. Paso Dellorto carb conversions. Ski-Doo/Bombadier Snowmobile part
# 570-134600 is a near perfect match, the important internal "rubber
washer" that mates the carb and manifold is spot on. 888 engine speed and position sensors - Fiat Tipo SEN 8D 907 ie. throttle position sensor (potentiometer), type PF09, is also
used in Alfa Romeo 33 ie Fuel pumps: Ducati 888 item made for Ducati by Walbro (their part
number 5CA305-3 (or 5CA305-2 for the white box).

friction plates - Suzuki GSF400 Clutch hub bearing: 6201 32 x 12 x 10 (OD, ID, thick). Get a 2RS/1C3.
It's a standard electric motor bearing, sealed on both sides. Clutch slave piston seal: "Quad Ring" part number Q4210-560ND
I believe that they need to be made of ethylene propylene (EP). Clutch thrust bearings: If you have a dry clutch with a 28.5 mm diameter
piston fitted with a ball race for the thrust bearing, you will probably
find that SKF bearing 630/8-2RS1 will fit, sizes are:

Electrics |
|
| Late bevel
fuse box - 'Durite' with spade fuses for direct replacement, part
number: 0234 24. Front brake light switch (hydraulic) for older models can be replaced
by a brake light switch from Volkswagen (Beetle for example), Audi
etc. The only difference is the threads, which are conical which means
that the washer is not needed. Oil pressure switch for some early belt-drive late models - Volkswagen
Polo. For newer Ducati models (original Ducati code 539.4.030.1A and
539.4.019.1A) - Opel Agila 1000cc. The General Motors code is 90.534.902. Paso 750 and 906 Marelli ignition coils appear similar to first model
of Fiat Uno. Paso Digiplex ignition unit appears similar to that fitted to Lancia
Thema 16V, Fiat Croma 1600 & Moto Guzzi Nevada 750. Regulator/rectifier - Honda CB250/400N Superdream, CM450 or CX500
(Shindengen part number: SH 232 127 - for many non-fuel injected Ducatis). Starter solenoid and flasher relay for two-valve twins - Rover/British

note that the outside diameter of the cage that holds the segments
together needs to be turned down to 65.5mm. 900ss, 906 Paso, Pantah engine starter sprag clutch: LC4 Freewheel bearing KTM Part No.58440026000. I just fitted one of these to the 906 Paso project, and it cost less than half the price of the original Ducati part.

Headlights |
|
| Darmah headlight:
a little cheaper as BMW H4 headlight glass /seal /rim. Indiana headlight: Yamaha Virago 535 and V-Max 1200 Monster headlight glass: BMW R100S, part no. 63121358147. Bosch part
numbers for Monster headlight glass & reflector (not available
separately from Ducati) are 1305604904 (Glass) and 1305304903 (Reflector) Pantah light lenses: the front flashers built in the fairing are the
same as mounted in old Fiat 850's front bumper. Tail light for Pantah 500 and 600 models are the same as mounted on
former Puch 50cc mopeds. Paso headlamp: Yamaha FZ750 of 1985/6 - Koyoto part number 110-31420

| 916 handlebar
plugs are much more expensive (but identical to) 600 Monster equivalents.
Bevel Drive 900 models (Darmah, Darmah SS, SS) with Nippon-Denso handle
bar switchgear is the same as on similar year GS series Suzukis. Handlebar switches on the current SS models - Honda XBR500. Right-hand
handlebar switches for 748/916 - Honda Fireblade Mirror assemblies for the current SS models. Honda CBR600 is also
a close fit. For the M900/M600 'Busch and Muller' part number BM926/37, similar
appearance and better visibility. "Baby Turbo" made by Vitaloni
are another alternative. Emgo mirrors for some Kawasaki ZX models
will fit. For the Paso and 907, mirror assemblies from the Cagiva freccia C12R
will NOT fit. Although they look similar, they are NOT interchangeable. 750 Sport Instrument clamps - 1980 BMW automotive air cleaner intake
hose clamps. 750 GT Handlebars - Magura Eurobend BMW style handlebar. Paso clock can be replaced by fitting the printed circuit board from
some Fiat models such as the Mirafiori, Tipo and Jaeger.
