Checking out some used 5 spoke marchesini wheels from a 2001 s4 that look like a perfect match for 03 800ss but seller says they take a 25mm axle front and back and my 800ss manual 25mm front and 16mm back. Does this sound accurate or does my rear take a 25mm as well? Would like a second set of wheels for rains or race tires for track days. Thanks in advance.
your rear actually takes a 17mm IIRC. I think you can change the bearings out to accept a 17mm axle in the rear, but I'm not familiar with Marchesinis, check the OD of the wheel bearings in the wheel and go to a local bearing shop and see what they can do for you.
Change the bearings and then the only other issue is the rear is .150" wider also at the right wheel bearing flange so the brake carrier must be machined down that much on the right edge (outside) to line up correctly. Make a simple .150" spacer and the carrier will work for stock wheels and for the ST wheels without the spacer. Done this a time or two...

Nothing is more satisfying than passing V4 Honda riders & Trolls!
I just put a set of 10 spoke Marchesinis on my '93 900ss. They were set up for 25mm front and rear. The '93 came with 17mm F/R axles. I had to have spacers made. I did e-bay a 20mm front axle to additionally stiffen up the front before having the spacers made.
Be sure that the width of the front hub is suitable! I believe that the standard width of the SS/916family front wheels are 105mm. The width of the front Marchesini wheel I got was 122mm. These wheels were not originally intended for a Ducati, but $500 for a set of NIB forged Al 10 spokers was worth the gamble. Fortunately, this was for my track bike, so I did not need the speedo drive pickup. It would not have fit. We had to get creative with the rotor-caliper alignment as well.
A good machinist can make the spacers, I'd be wary of fitment if you mail-ordered some. I would recommend taking the whole bike over to whomever does the work.
I have a New Carbon rim with Mag center hub (white) and a 5 spoke (black) Mag for sale.
Both are new ,,,never had a tire mounted..I have them listed on the Ducati Monster List right now.
Email me at wmfleet2@verizon.net
Both are for a S4,,,I was hoping to mount them on my 98 m900 ,but will take to much machine work.
Wondering if the oems for my year and model are any cheaper than what some distributors are selling marchesinis for. Found the part # on the parts downloadable cat. but no price. Anyone? 2003 800 ssie

I am in the same dilema as you describe. I have a new set of Marchesini wheel and it appears the front hub is the 122mm as you mentioned.
My question: What did you do about rotors? Did you make adapters for the calipers?
So I had some spacers machined for the rear wheel and it fits great. This done through Al at MotoCorse in Ft Lauderdale. He does some awesome work.
Now all I have is to figure what to do with this 122mm hub front Marchesini wheel. I may just fit it onto my GSXR and get a new front wheel for the Ducati.
Love those Carrozzeria wheels too. Were those specifically for the Ducati 800?
They offer that wheel for other bikes but they customize the cush drive for the ss model along with spacers, etc. Tightening the wheel nut is half the OEM torque value because the ball bearrings are twice as large.
I bought a set of Marchesini wheels for $750. I took the chance that it would fit. The rear fits but the front hub is too wide for the Ducati. I am now looking for a Marchesini front that will fit the Ducati and figure that I may still be ahead as far as money goes.
I am racing the Ducati 800. It has some HC pistons and mild cams for a reported 86rwhp on a Superflow dyno. It runs pretty strong and will run against a strong SV. Certainly won't keep up with those mega motor SV superbikes.
Thinking about some mods for next season. What did the HC pistons run you? Any engine reliability issues? Also wanted to get a custom map from a dyno for both pistons. Heard that might get me a few hps.
The HC pistons cost around $800. MotoCorse out of Ft Lauderdale did the work for me. I have only been running it for a couple weekdns now with no issues whatsoever. There are quite a few Ducati 1000 and 800 in the Florida Region of CCS. There are probably 6 Ducati 800s in the region a 750 or two and close to 10 of the 1000.
Got a custom map through MotoCorse as there isn't an actual PC for the 800. I believe the 1000 was used but not sure which 1000 off the top of my head.
Did you use the stock con rods with those pistons? What class do you race the 800 in? I like to run on Sat. so I'm stuck in lightweight ss with the svs. But it brings even more satisfaction when I pass one. There are also some hawks and motards to contend with. Its a nice mix.
I typically race the Ultralight class with my FZR400 and I am leading the Florida Region for that class. I won my race in August aboard the Ducati, which was a rain race, but I just don't have enough time on the bike.
Raced Daytona ROC in October but did poorly. There again lack of ride time on the bike and that layout. I went a lot faster on the last lap than all the previous laps. I have some suspension set-up to do before this thing will fly.
I am also looking at racing the GT Lights class due to the fact that I got my first "money race" back in August on the FZR400. If only I were on the Ducati.
The bottom end including crank and rods are stock. Chris Boy at Motocorse claims that they are more reliable and he has had better results than the highly modified crank or rods.
I have yet to race this thing in anger but I believe I will give some of those 1000 riders something to think about.
