DS1000SS Nekkid Roadster Build

[Nekkid Tim]

Build is an homage to the 1973/1974 Ducati 750 Sport, using a 2006 DS1000SS as the starting point.   Not meant to be an exact REPLICA of the 750 Sport, but to pay tribute to it with a lighter, more powerful, model, while using as many oem Ducati components as possible, with the bike being very light, very comfortable (thus, no clip-on handlebars) and very street friendly.  No lightweight flywheel, no high compression pistons, no straight pipes, but tractable and flickable; not a track bike.  So it will have lights, turn signals, a horn, etc.   Target wet weight is 360 pounds.  I think.

Rough mockup; featuring a "Sprint" model ETI Fuel Cel, a Monster front fender, a Ducati 916 monoposto tail, BUB Enterprises slip-on exhaust, a "razor cut" rear rotor, and a early model (first generation; 1991-1998) 900SS/SP alloy sidestand with alloy mounting boss.

At this point the bike already has had the rear part of the oem steel one-piece frame cut off, and tabs have been welded on to accept an oem Ducati 916 monoposto aluminum rear subframe:

The "rider's eye" view will include these European Ducati GT1000 Sport Classic gauges, a Flanders "superbike bend" chrome steel handlebar, and Ducati 999 Superbike radial master cylinders (clutch and brake) with integrated fluid reservoirs.  This is a stock S2R1000 triple clamp assembly with the top triple being the S2R800 item sized for a standard 7/8" handlebar.  The triple will have to be modified to work in the 1000SS steering head, as pointed out by multiple forum members:

This is just a bunch of carbon fiber parts sourced off of eBay; trying to make the bike as light as it possibly can be and still be street legal and look somewhat "stock."  (Albeit stock Ducati stuff from multiple Ducati models!)

the ss uses different steering head bearings to the monster, so the monster lower triple won't fit the ss frame.  i think the offset is different also.

[Nekkid Tim]

I did this with a 1992 Ducati 750SS a million years ago, using Monster 900 triples.   Will have to investigate the different bearings available.

Along the lines of what Brad said:

DS1000 - 0691.91.010 Bearing

S2R - 702.4.004.1A Bearing

[brad black]

I have new steering head bearings.  The offset is different , but as I mentioned; I have an S2R top triple.

are they special ones to mate an ss frame with a monster stem?  ss stem is 26mm, frame 52mm, monster stem is 35, frame 55.  i don't know of a 26 x 55 bearing, but all balls may list one.

1st gen monster is same bearing as ss, the triple you show is second gen or st frame.  hence our input.

the bearing required doesn't exist afaik.

If the monster stem is 35mm and the SS frame is 52mm (I haven't measured anything; both my SS's are in Winchester right now) wouldn't I need bearings with an I.D. of 35mm and an O.D. of 52mm; not a 26x55?

sounds right to me.  still can't get them afaik.
