    Hello

    I plan to "rebuild" a twin front tank from the Mecasystem one.

    Mecasystem twin tank

    The tank is the same model used for the up to 2007 and after 2007 KTM frame/engine.
    Only the fairing is changing and of course the aluminum supports (because of the frame differences).

    Until 2007

    From 2008

    These Mecasystem are quite good, but some Dakar riders explained me the following:
    - The weight (tank full) is to high.
    - The tanks are going to low, so they are receiveing many chocs
    - The tanks are not allowing enough air circulation around the engine and carburator.
    => Many vapor lock issues.
    => Many heat issues with the engine.
    1. Can you guys confirm or not these issues ?



    2. I don't want to have 20 liters (like these 2 tanks together), but I want to have more than 15 liters (this is what I have with my current Safary tank on my KTM 525 exc).
    I will rebuild the 2 tanks in carbon/kevlar but:
    - I will reduce the total capacity to 16 to 18 liters (less weight)
    - I will add extra space between the tank internal face and the enfine (more air circulation)
    - I will add extra sapce between the tank and the water radiator (more air circulation)
    - I will raise up the bottom of the tank (less chocs)
    Any comments ?



    3. I should receive the 2 Mecasystem tanks from a friend next summer. Then I will made a mold.
    I could start faster if I could get some tanks sooner, even if they are perforated, melted (=> unusable).
    If somebody has this in its garage before it goes in its garbage !
    Of course, I will pay the shipment !

    Thx

    I don't have Meca tanks but some that are IMO better:

    I would only sell them with a complete Rally kit for the KTM EXC though:

    Ok, this time I found them: 2 front tanks in a very fgood shape at less than 50% of the price for new parts :1drink

    This was not easy to find as they are the best parts of the Mecasystem offer.
    It seems that most of the drivers keep them...

    Hopefully this kind of parts are more common in Europe.

    Thank you to some of you who have provided some solutions.
