Ducati Monster Forum

I'm trying to come up with a table to determine engine size and model year from just the engine number.

I've searched online, and not found any help.

So if you can, check the first four digits of your engine number, and report it here along with year and engine size.

Most helpful if you're the original owner, as pre-owned bikes can have had undisclosed engine swaps....
But still report it if you're not, as engine swaps aren't real common.

For example, the first 4 digits RC3X mean it's a '99 M750.

TIA!  [beer]

ROUGH DRAFT TABLE

Years, 4th digit

1991 = m 1992 = N 1993 = q 1994 = r 1995 = s 1996 = t 1997 = v 1998 = W 1999 = X 2000 = Y

2001 = 1       2002 = 2       2003 =       2004 =       2005 = 5       2006 = 6       2007 =       2008 =       2009 = 9       2010 = A

2011 =            2012 =            2013 = D            2014 =              2015 =            2016 = G            2017 =

***** UPPERCASE are verified, lowercase are inferred, some letters may be skipped *****


First 3 digits, Model:

RA2 = Injected M620 RAD = Injected M695, M696 RC3 = Carbie M750 RA3 = Injected M750 H74 = Injected 748R SBK SB3 = Injected 748 SBK UB3 = Injected 749 SBK RAA = Injected M800 LAA = Injected 800SS

XBG = Injected 848SBK      1BM = Injected 848SF      HB6 = Injected 851SBK      RC4 = Carbie M900      RA4 = Injected M900      LC4 = Carbie 900SS      PC4 = Carbie E900      RB8 = Injected S4 (916)      SB8 = Injected 916 SBK      SB5 = Injected 996 SBK      RB5 = Injected 999 S4Rs      RAB = Injected M1000      WAB = Injected SC1000

XBE = Injected 1098SBK           YAC = Injected Multi 1100           RBS = Injected M1200

Where's the number stamped at?

On the left side of the crankcase, below the alternator cover.

It'll be something like RC3X014529.

First 4 digits are all that's relevant to model and year.
Last 6 digits are sequential to identify a particular engine, and not useful.

Service manuals have info that's helpful if it's a non-USA model, but insufficient detail for USA models.

95 M900
ZDM904A2C

Cool, thanks!

Anyone else?  [popcorn]

I'll dig mine out of the rubble in the barn tomorrow.

96 M 900 and an '01 996.

2002 620 RA22
2003 800ss LAA5 (Bought the engine which was sold as a 2003 but the year may be wrong.)

Eeeeexcellent, thank you both.  :)

Thorn14, the '5' of the LAA5 denotes a 2005 engine, from what I've found.

ZDM904A2C. same as Koko
Late 97 900 (has 3 phase from new)

'07 695: ZDM6

ZDM1

2009 M1100.

Was confused why my numbers seemed different to others, and I was researching, and I'm seeing that the country the bike is imported to matters, as the numbers are different for US vs other countries. The ZDM standing for only appears on my US frame, my engine begins at model of bike (monster). I figure I may as well share this info from two sources.

One I found which I hadn't seen before... showing the differences between numbers.

The first link in google which I assume you've seen Speeddog.

nick is asking for usa style engine numbers, which are different to the euro ones.

zdmxxxx does not apply to the usa.

2000 900Sie    RA4Y

1992 900SS    LC4N

1996 M900 RC4T

2000 or 2001...not sure and can't get to the vin right now...996 Bi Posto SB5Y

'01 750  RC31 or I, not sure.

Nick
You want just US numbers or going international for the archives?

Originally I was thinking just US, as the numbers are less obviously informative, and not explained by official documentation (that I've found).

But there's no reason to exclude the rest of the world in this, we're all in this mess together.  ;D

2000 M 900ie    RA4Y

98 M900 RC4W

2005 M620 ZDM620A2B

then cooling, Air or Water

then # of valves per cylinder

then variant

then engine number in sequence, 6 digits.

2003 monster 1000 dss

was gunna post the monster and 748, but Brad has it covered with his post.
they're the same as he has written...

So on the US models the 3rd number is the displacement and 4th is the year it was built.
As Nick has posted the dates are the same as the vin so prior to 2001 you have a letter for the year. from 2001 onward you have the year (number).

3rd number does not seem to matter if it is a monster or a supersport, they are only concerned with displacement.
900 = 4
996 = 5
750 = 3    (note a 748 is the same as a 750 2 valve as they both are 748cc)
620 = 2
800 = A
851 = 6
916 = 8
1000 = B  (should be both 2 and 3 valve)
695 =  D

My 650 has a completely different engine number and the ducati engine in the grand canyon has a non-US type engine number ZDM*****

Good for finding out if that 996 cases are a 748 or a 996, though you have to watch out still as I have a 900 that is an 853 and a 620 that may soon be a 795 and a 695 that could easily become an 800. I have also built 916 cases into an 851 and 748's into 916's.

I think we've almost got the Magic Decoder Ring assembled. :)

03/05/14 Updated table in 1st post

And then Ducati throws you a curve..........
Just noticed my new trackday cases engine VIN starts with H74
Should be 900 cc engine by what we have found right?

Sorry it is a 748R

So maybe the trend is only for standard production cases.
Oh and the 851 cases I have start with HB6

I know you already have this info in the table, but here is mine anyway:

2001 M900Sie.  Fourth owner; I know the third didn't swap the engine but can't speak for other two.  That said, nothing in maintenance records I inherited suggest a swap.
