    Share your stories and pictures of Montesa Cota 25s, 49s, 80s, 123s and 172s also. These weren't super popular in the States so I don't expect this to be a very busy thread, but here we go anyway!

    Recently I acquired (rescued?) a 1972 Montesa 25 from the Ozarks thanks to a single pic taken by Dyrwolf. 1350 miles and a day travel time later it was mine.

    I parked it next to the Team TY80s in the shop to decide what to do with it.

    Don't let the pics fool you, after sitting in the woods for decades this thing is pretty bad. Rust and corrosion are battling for supremacy, lots of missing and butchered parts are vying for 2nd place. I will admit I was considering a TY80/Montesa hybrid. When I mentioned that to Lineaway he told me that the Montesa Faithful would probably crucify me for such blasphemy. I told him that I AM the Montesa Faithful. He just laughed and wished me luck with that. After spending some quality time with a measuring stick I came to a conclusion:

    This thing is TINY!!

    It makes a TY80 look huge in comparison. If I do decide to move forward with the Yammie engine swap it will not be an afternoon job. I was however getting tired of carrying it whenever I needed to move it, so yesterday I scabbed on a pair of TY80 wheels & tires just to have a roller. They fit (sorta), and the little 25 rolls for the first time in years.

    So what will happen to this little 25? Dunno, but it will be a runner as I am not into museum bikes. Parts can be found on Fleabay Spain (at heart-arresting prices), so getting the little German Jlo (no kidding) engine going is possible, and the front forks will have to be upgraded to the later model style that is an actual fork assembly instead of the cheeseball (and rust-ruined) MK1 fork this one came with. A TY80 fork assembly is being considered also (I have several). Who knows.

    More to come! :D

    I've been flamed for saying this before, so flame me again. My first real trials bike was a Cota 123. I don't have any pics of it, but if I did I would prefer for them to images of it burning into the ground. Man, how I hated that pos.

    But good luck with your baby Cota, Brewtus. It's gonna be mighty cute.

    I had a baby Montesa 45+ years ago. The original engine was not worth fixing for some reason. Dad put a Hodaka engine in it. I still have some super 8 film transferred to vhs transferred to dvd of me riding it.
    Maybe you can find a Hodaka engine.

    The Cat 80 was a much better bike in every way.

    I don't know how to make a still image from video, then put it on here. I can tell you I was more interested in going fast than Dad wanted. That video is of me sliding the Montesa around.

    My brother and I both had Cat 80s. My brother's cat engine wound up in a YZ80 frame, about as good a woods minibike as there was 40 years ago. The YZ80 engine found its way into an RD60. I rode that on the street for a while. Beautiful dark green RD.

    Here's a Cota 123. Was in a little better shape than the one in the back of Brewtus's truck. This is a buddy of mines bike. We spent a lot of time on this build, and not just for looks. Motor is rebuilt as well. I lost count how many times we split the cases, after the rebuild, to get the transmission to shift right. Bike runs great, but ended up being my buddy's wife's bike and is used as a trail bike. Never been in a competition, but after playing with it, I think it would do well.
    It earned 1st place at the World Round bike show a couple years back in Exeter RI for Best European in Show.
    Bike might be coming up for sale too!

    I can remember wanting one of those so bad as a kid. Luckily I did not get one. Instead an Ossa MAR which served me well. I would have detroyed that little cota.

    While prepping a buddy's Beta 390 for surgery the other day, I couldn't help thinking that without a front fender the 25 looked like a Flattracker. A spare TY80 (what else?) fender was zip-tied to the spindly forks making it look more like a proper Trials bike.

    So it rolls, making it a heavy yet cool-styled Strider. More to come! :thumb

    It would be a shame to do anything to Little Monty but hang it as wall art!

    Having seen it in person, I find the depth of crusty to be beautiful as is. The definition of 'character.' One step toward 'Improving' it starts one down the long path of the time-sucking device extraordinair:augie

    Yeah, I wish my brain worked that way. I don't own motorcycles for art, I own them to ride (eventually). There have been several votes for yard or shop art for the little Cota, but I just can't bring myself to do it. It will get futzed with in between futzing with the other bikes. :D

    I love my '85 Cota 123, the "newer" Cota's have quite a few improvements compared to the bikes front the "70's........although many would say still not enough...
    Mine was a little rough when I got it so it has been freshened up a little, it no museum piece and it gets thrashed on regular basis in the vintage class at NETA events.
    When I first got her.

    The late model little cota`s (123,200) handled very well. I loved mine until they made our vintage sections too hard to keep riding the Cota.
