    Default Bitza Racing of early 90's

    Winter and snow arrived and workshop is frozen, so I am taking time to present the bike of a friend as he asked me.
    He presented himself here, but as he doesn't speak english he cannot do it.
    For his 50th he bought a Racing he found over a year and half before.
    I was coming with him to see the bike around a year ago and he finally could buy it last summer.



    And I came to see it again once in his garage and we made a little autopsy to see what parts are inside.

    The Ducati dealer well knew the boss of Giocamoto who offered this bike in 1992.
    All the modifications were already on the bike when it came in the beginning of 1992 in Swiss.
    Birth of the bike was in October 1991.
    Due to the parts on it, I think the base was probably an improved Racing '90. But the frame is a Racing 92 version.



    The bike was coming in this bronze color of frame. The Ducati dealer who engaged the bike in race in this period said he never modified or repainted a frame.
    The frame number were invisible, under the bronze and two coats of white painting.
    My friend removed the painting in the number area and checked it with the factory.
    But they said it is an 888 SPS... I made for him a document with all details of the bike and especially of the frame with specificties we can see only on Corsa frame, but they answered it's an SPS (even with a welded frame ?!!)





    The bike was imported as a Racing bike in Swiss with this "SPS" frame number (first invisible because of the painting so I thought it was a spare frame without number due to older parts), but maybe they already made a real SPS frame with this number because the number was scratched but still visible.



    Maybe the bike served for developping new things, because this frame is originally a '92 corsa frame. It was modified to use the Giocamoto '92 footpeg, and the reinforcing bar was made removable as a '93 bike.


    Even if the bar was removable, the airbox is still in three parts.


    The rear oil box breather was probably added after. But we don't know if the bike already have the 888 rear seat (I saw on SP4 prototyp made with an SP3 bike in an official ad). The rear subframe is still the 851 SP/Racing version modified (tinkered is a better word...) for these parts.


    The fork is an FG9050 inverted for using big offset discs (with mag' triple clamp). The rear shock absorber is an öhlins too, with a red spring.

    The AP Racing set (discs+calipers+master cylinder) is original from this period, because the Ducati dealer was sponsored by this brand, so they changed the Brembo set for AP on their Racing bikes (I saw a pic on a R92, where they still have the little rear Brembo caliper with a AP sticker on it).


    The rear one is still Brembo too. The rear wheel is a Marvic used on R90 bikes, with road swing arm and road discs (so it correspond to a R90 mounting).
    The front wheel is a Marchesini probably changed after.



    The radiator is a Racing version, but not the version of 91-92-93-94. It has 22 rows, but the lower pipe is like the road version. This black version looks like to be the R90's radiator but it's hard to find an original one (looks like the one of ex-Richard Hubin, which is probably the most original one I saw except for the exhaust system).


    The fuel tank is a Giocamoto carbon version, and injection unit uses well four green injectors.



    A beautiful Termignoni exhaust for R91-92 (the same I want !!!)

    There is a "Zeltweg '91" chip in the P7 unit.




    The bike raced until 1994 and served also as training bike, before it was sold to the new owner who used it few until 1998. And the bike was probably never start until this period (Then my friend bought it last year).
    The engine was totally serviced and rebuild in 1994. Never broken after, so all parts are original from that last rebuild.

    The engine : half crankcases are from a "90" mould. No number. So a new set for a '91 bike (I want theeeeem !!!!)
    Clutch cover is well in magnesium as you can see, with a racing clutch.


    When I came last the summer, we tried to know if it was possible to restart it easily. But when we wanted to drain the coolant liquid, "sand" fell from the pipes. All was dry inside so we prefered to not restart it now. The bike will be refreshed after this winter and repainted in red as originally (the previous owner repainted it in black the only one modification he made).
    So we have removed some parts to see what beauties were inside.

    We don't have remove the alternator cover, but I'm pretty sure that there is the original Racing flywheel in it (It looks like mine when I had looked through the little porthole).
    There is no starter.
    So we remove the rear head and piston/cylinder to see inside.

    We have to wait the opening to see what gear box is in. But the crankshaft is an original Racing one. Well polished, with a pair of Pankl 20 mm conrods.




    The pistons (093650) are 94 mm, but not the Racing version. I don't know exactly from what it was taken. It has a dome of compression yet but not very high. So I tought it was an SP4 version but I am not sure at all (I saw an old ad with these pistons which spoke about SP4 too... but if someone can confirmed ?)







    The head is "G" marked. Still with original 34/30 mm valves. And use G/G camshafts... not bad ;-)






    The pulleys are lightened (ergal pulleys with lightened spacers).


    He also wanted eventually to know if someone have already seen this kind of modifications on Racing frames before 1992 as this one.

    Happy to see that the bike is appreciate

    I will follow the refreshing of the bike (made by another 888-rider-friend, who restored bikes and who is near from me) and help for some works on the engine.
    So I will give more details when the bike will be disassembled (it will be helpful for my R91 rebuilding too).

    Family picture...


    Guy : As far as I know these footpegs are the early version of racing rearsets made by Giocamoto before Ducati made them in carbon in 93. And be probably at the performance parts catalog for 92-94 bikes.
    I also have a pair on my "strada".
