    Welp, I bought the Montesa. Sans Head.
    The seller significantly lowered the price for me.

    Then I found this.
    I'm 99.9% sure it's a head for a 123. Seller has it listed as "Model Unknown"
    Anyone on here knowledgeable enough about Vintage Montesa bikes to know for sure?
    I've already bought it. But I won't see it until the border opens up.

    Anyone on here VERY familiar with Mid 80's trials suspension?

    I own a 1985 or 86 JCM 303. I was told it had Marzocchi forks.
    I'm starting to believe that may not be correct. The reason I'm wondering is that I'd love to see a schematic for mine. I'm rebuilding them from the 5 gallon bucket of parts they came in, and there is no retainer clip for the main oil seal. No groove for a clip either. Does the seal just stay in all on it's own with friction? Nothing holding it in?

    My bike has the same forks as this photo of a JCM 243. Supposedly they are Foral Conventional 35mm forks. Which I can find nothing online about.

    This second photo is another JCM 303. Not mine. Supposedly it has 35mm Marzocchi forks.
    You can clearly see the differences. Even the triples are different.
    My bike has the same triples as the first photo of the 243.

    Can anyone positively I.D. which fork is which from these pictures?
    And can anyone confirm that suspension from the 80's didn't have a retainer clip on the oil seal?


    Here are a few pics of my forks. The first picture has the remainder of the only marking on them.

    Found 'Em!
    Thanks for all your help folks! :lol3

    They are Foral Conventional units. Also used on the TX line of bikes from Aprilia.
    They actually appear to be EXACTLY the same as the Aprilia forks, so much so that they had to scrub the Aprilia logo off the bottom of the fork leg! :imaposer
    Found this picture on an ebay listing.

    Jepp Foral is mounted to Aprilia TX and TXR and provides good performance but not excellent.

    CDN Rick..... have you been in touch with Steve Troupe about the JCM? He used to be the Canadian importer back in the day and could be a valuable source of info. I was talking to him at the Toronto bike show back in January. He’s into restoring old Italian bikes now.

    I don’t have his contact info handy, but I’m sure there may be someone in the SOVT club with it.

    Just bought a 74 TY250. Pretty good shape. Has ape hanger bars on it, that I'm going to change. Also vibrates "a lot". Is that normal?
