    I have just become the owner of a new Ossa 280. I have coveted this bike for many months and its finally a reality. But I just cannot start it. Others have. But I seem unable to find the trick to it. Can anyone help me. My soles are bruised and battered and the bike sits looking like a bitchy virgin on her wedding night. Help me.

    Hi Guys, My 2012 Tr280i Ossa shut-off while riding and did not want to start again. I’ve already check the spark plug (was dirty/black), checked the air filter (was clean) and checked that the gas pump was working and it was. Then, I replaced the spark plug … but still... doesn’t want to start. I guess the next step to test should be whether there is electricity or spark being generated?... however. the spark-plug cap is so deep that it seems pointless to put it against the frame and kick it to check it (as on a regular carb bike) + this one being a fuel injected… I don’t know whether the best thing to check is through the “Diagnostic Software” ? or is there any othe…

    I would have thought that enough people actually own a TR280 to have run into some issues or concerns by now? If so please share this with us. Best of balance. Neo

    Hi all! Just checking around if anybody has any news about Ossa. The rumour says they have moved into a new "factory (setting up a production line)". However no press releases or info/sign/rumours of a 2016 model is not that promising. They can't afford another no-sell year. /TJ

    How come this thread hasn't got a OSSA pic thread yet!? Here's my TR280i, 2013 model: (Pic with a 5x7" view camera made somwhere in 1920/30s, lol) Come on, show us yours! From the classic OSSAs to the new radical modern trials cousins - we'd love to see 'em all...

    Hi All, I've always liked how the ossa TR280 rides after a brief ride on one last year , and have had my eye out for a good second hand one to purchase. But after whats happened and reading the posts on "Kokusan Denki No More" What are peoples genuine opinions on taking the plunge and buying one ? ie. For's.....You could probably get a good one now for reasonable money ? Against.....Getting it repaired (spares) problems ? Thanks For your opinions.......Craig.

    Hi Like the look of OSSAs. Worried about reliability issues. Faults? Would I regret buying a 2012/13 ? Thanks Tony

    It's looking a bit ratty and I want to do a couple of things to the bike to make it more suitable to me.the frame is going to get a black powdercoat,the triples are getting black anodizing and i'll change the airbox cover for the new style vented one.I'm going to try and see if I can get a 2015 sticker set for it if it will fit the 2011 plastics.Might have to get a newer seat base and bendy rear fender.While the engine is out,another base gasket is going in to make it easier to kick thru.I doubt it will effect low end power,but I might lose top end.Never use all of it anyway.

    Apparently a new Ossa will be shown at the Milan show on the 10th of November. Called the 280TRI its not known if its two stroke or four stroke, and there is speculation that the I might stand for injection.

    Look, it's a slow day at the office and I've been worrying about the price of this here, new bike? In comparison; what makes (made ) the Montesa 4RT so expensive? Is it because it's a 4stroke engine and they have more mechanicals?...but Beta/Sherco seem to manage to keep the price down on theirs .OSSA has a 2stroke. Or is it because it has an alloy frame?..again Beta seem to be able to moderate their prices. OSSA has a steel tube frame. Or is it (as I suspect ) Fuel Injection...how much does that add to the price of a trials bike? I'll give you a further insight into my logic process :- When I look at a new trials bike I try to imagine (like we all do) what…

    Hi, after finally finishing the rebuild and starting it up I've a problem with the clutch. At first I thought that the plates were stuck together but it's the action that's the problem. I pull in the lever and it stays there until I manually pull it back. It's a new cable, so I don't think that's the problem. Any ideas gratefully welcomed. Also the carb seems to be in need of adjustment. There only seems to be one screw that I can see, it's on the l/h side of the carb but I thought that it was the idle adjustment. The bike starts fine but if I stop it and try to re start it won't unless I remove the plug and clean it. Help!!!

    Hi all .. looking for some un-biased thoughts .. I have been looking to return to trials , and one of the bikes I have seen is a Ossa Tr280i , 2012-13 .. the bike seems to have had very little use , and has had two owners ,, the first owner had issues with the bike not running correctly and would go through plugs, so the bike wasn't used .. The second own was an older guy , and I had been told that the previous issue was to do with the fuel mapping , which had been corrected and so I'm told the bike is running good .. the second oner didn't ride the bike hard and put very few hours on it .. So now I have been thinking about buying the bike , I have look…

    I am looking at a new 2013 bike. Trying to decide between the OSSA , Beta, and Sherco. I'm an intermediate rider. We ride woods with steep hill climbs and steep rock sections, some longer trail rides; all in big mountains (British Columbia). Any comments on the Ossa bikes? Some people are saying the the FI isn't quite there yet, Carbs are still better. How about general quality and reliability? Any suggestions what you would buy if you could get a new 2013? Thanks from a research (and trials) addict.

    I'm new to this forum , just bought a 2012 Ossa tr280i , not really happy with the engine feel in bottom end and it keeps on flooding. So I'm trying to understand how the FI system works , I understand FI but I don't get how the Ossa does its calculations , my MAP sensor is In the outside air not the manifold , so is the amount of fuel dependent on the throttle position? (With some tweaks for engine temp etc) so the map sensor is only monitoring the barometric pressure ?
