    Oh c'mon, Trials tires are meant to be replaced every 6 years (minimum) or so, right? :lol3

    Cota 247 tanks were red only. Nice bike. The motors are bulletproof. Kick stand should be mounted on the swing arm. Get some new foot pegs. Those stockers will clog with mud in 5 minutes.

    If you decide to paint the tank don’t use a DA sander. You’ll wipe out the ridge on the size of the tank. It looks like the indentation for the tank badge has been filled in with bondo.

    I talked to Mr Dedon this morning because that’s the kind of stalker i am. The bike was originally red/white and riden by the shop mechanic. The mechanic painted it yellow no significants other then he liked yellow. Mr Dedon rode trials on it for a few years but it always popped out of 1st gear. To his knowledge the gear box was not repaired

    I hadn’t been on my old Bultaco since the last time we hosted a trial three years ago and I must say that rear brake on the left side makes for some interesting décents...:p3rry

    Especially for member MATTY from the Scottish border here some information about the suspension of the Ardie, as it is About an old bike it fi here:

    [​IMG]

    The Ardie is a model BD 176 manufactured in 1953.

    The telescopic fork is really clever made, with a hydraulic dampener that is even progressiv, the trick is that the middle rod is konkav formed thus gives more room for oil to float in the middle and less at the ends which are the beginning and the end of the fork, so at first you have a vit stiffer setup in dampnung and of course i the end to avoid bottening. See in the section from the manual of the bike.

    [​IMG]

    The rear suspension is from Fournales and a custom made shock to fit the bike, only run by air and oil. Also highly progressive and light too. These where used by Philippe Berlatier back in the late eighties in world championship. The shocks are a bit complicated and are using different funnels to archive the progressiveness you want,
    you have to know what you want in forhand, the shock will then be build to that adjusment there is no later changes possible. I had them too back in the 80's and
    I can talk a bit French because you have to discuss the set up with the manufacture, otherwise he will not fabricate them.

    [​IMG]

    Here in detail you can see the dampning works likewise as the Ardie,
    with funnels of which different are used depending compression or rebound!

    Most import is engine perfromance and weight here this little engien has some advantages,
    it was constructed in the early 50's by Fritz Gosslau who was an aircraft engineer.

    Gosslau was an employee to Fieseler in Kassel and constructed the Fieseler Stroch (first ultralight plane)
    then the Fieseler 103 also known as the V1, the first cruise missile.

    After the war Gosslau went to Dürkopp a motorcycle manufacturer in Bielefeld, there he developed the two stroke engine
    as Dürkopp wanted an own engine and a motor which was easy to produce, still very powerful, (it was still after war times
    where everything was in shortage) and economic in use of gasoline.

    But Dürkopp did not had the machinery to produce engines so the gave Ardie the order to produce the engine.

    Ardie was not only a motorcycle company they manufactured also hydraulic components, thus had quite an experience in
    doing so and a broad range of hydraulic products.

    Later on the motorcycle department of Ardie submerged with Dürkopp as they already shared the engine development and Ardie
    only focused on hydraulics.

    The hydraulic departement of Ardie then submerged in Ardie-Hydronorma, and is now (up until today) still alive as Luvra Systemtechnik making all
    kind of fancy big hydraulic systems for all kinds of proposals to many other manufacturers world wide. Thus I was determinded
    to use real hydraulic components here too.
