OSSA

Damn!......that is a good looking bike http://www.trialscentral.com/news-archive/trials-bike-news/15903-ossa-launch-factory-r-2014

Would appreciate assistance from anyone who has fitted a Mikuni VM26 to a 250 Ossa Gripper. Have tried a number of main & pilot jets, needle sizes etc without real success in getting the bike to run right.

Anyone tried one or have any information on how good or not they are? and also how much they are? I like the idea of having idle adjustgment without the need for leads or the software, or having to take it to the dealer, but of course it will all depend on the cost!

The rear wheel needs a new bearing.There is only a bushing and an oilseal on the other side.Anyone have this bushing out?

Hello There, I'm quite new to trials and in fact motorcycles. I just got my new "used" 2011 Ossa Tr280i to finally start learning about it. I've just been a couple of hours on it and decided to give it a good clean from its previous owner... and the fun began; while taking off all the dirt and grease I found a couple of issues listed below,...that have not idea how's better to address... so any tips, suggestions and recommendations will be appreciated. 1. Crack in the muffler - close to where it connects to the exhaust (see pic) 2. No clip master link - I only know the chain says "Iris" on the links. What should I know to get a new clip master link?... how to order it…

Hi, I was wondering if anyone could give me the measurements of the sidestand bolt from my Ossa mar. The chromer has managed to `lose` mine, it maybe in the bottom of the tank but it will be a while before he empties it!! Thanks in advance, Nigel.

Well after a series of c0ck ups with powder coating colours and out of production factory decal kits it seems the facelift on my bike is very nearly complete. Here are a few pics of the FUTURE kit ... available from H&D Racing ... a bit different to the usual green but I'm loving it. The pics on the site don't do it justice and I was swithering before going for it so hopefully this will help someone else make a decision. Quality is great as is fit and cheap enough too

Anyone out there coming from a GasGas (or Beta for that matter) curious what differences are noticeable. Stability, grip, turning, power, typically reliability issues. These bikes remind me most of a GasGas. I'm wondering if they have the same light feel and neutral ergonomics, is the head angle overly steep (tendency to tuck) Read a lot on here where they grip well, one rider said pegs felt high compared to other bikes. Let's hear it!

Anyone had the misfortune to snap off the 90 degree fuel outlet elbow? If so did you manage to get the part?

i have wanted a new sherco for quite a while now but recently the ossa as caught my eye, i am hoping to buy a new bike in around a months time, it looks very easy to clean and i quite like the idea of the easy start, i can't afford a new one but i have seen 2012-13 in my price range so i was hoping for some honest answers on the good and the bad points, things like are spares easy to get hold of and are the spares a reasonable price, are they easy to maintain, is there well known problems that you know of.

So there was I thinking this makeover on the bike would be a 2 minute job . Long story short ... Eventually decided that I wanted to put a factory sticker kit on my bike and do the frame white so ordered the sticker kit through my local dealer. He was told it would be here in a week ( which ends today ). I get a call from him this morning saying that they are no longer available?? How can a sticker kit from last years bike not still be available. I do have a 2014 tr280 sticker kit here but wanted something a bit different. Frame is lying bare and ready to be powder coated Is there a 2014 factory kit? Anyone post a pic?

Hi, before I start with the big hammer and brass drift is there any advice on the best way to remove the wheel bearings on my bike? I`ve made the mistake of painting them before I decided to renew the bearings Cheers, Nigel.

Hi, Im running an Ossa 2011 with an update clutch (internals) to 2012 specs. First of all I love the bike - it is amazing in every aspect except for the clutch engagement in my opinion. To me it seems the clutch is engaging at different positions ( a millimeter or two in or out) this occurs the first time used after heavy use ie revving and shooting off. One could say it bites slightly better after a hard use. Bike has less than 20 hrs on it - will it get better or should I consider bleeding the system, changing the clutch lever oil reservoir to a bigger size? Or just plainly used it hard to see if it beds in better? Thanks in advance, K.

My tr280 rear lower chain guard is busted. Does it have to be an OEM one or is their a better aftermarket one that will fit? thanks

Hi, can anyone recommend how to remove the wheel bearings on my 1975 mar? I made the mistake of painting the hubs before I realised that they needed renewing I usually use a hammer and brass drift but before I attack them I was wondering if there was an easier way. Also what gauge are the spoke nipples? The spokes have polished up alright but the nipples are a bit mankey so I thought that I`d replace them. Cheers, Nigel.

Help, please. Where's the level-plug and which oil is recommended ?

I have a 2012 TR280 running ECU 11 firmware and map #15. Just wondering if this is the latest map update for this version or have more been produced? I used to get updates from Bob at OSSA Canada but that is no longer an option. Australian distribution and back up is not much help at present either. Any suggestions? Cheers

Did Ossa have a mid year graphics change? I have seen two '12s for sale with '13 graphics. Both bike are like new with no time on them. Neither bike has the white marzzochi forks on them. If they did have a change, is that also when the new style air cleaner was added. I saw a previous thread that said the very first '12 didn't have the air cleaner update.

At a recent event my bike got knocked over and it bent the crap out of the mounting plate of the side stand. Can someone shoot me a close-up picture of theirs so I know how to bend it back into place? thanks

Hi....again, can anyone tell me how to measure the offset of the wheels on (off) my 1975/6 Ossa mar? Or what the offset is. I`ve decided to give it a go myself, wheel building that is. The tyres are now off and the nipples are soaked in WD40, might give them a while before trying to undo them as I`d prefer to re-use them. The rims might take a while to clean up, looks like they`ve never been cleaned from new!! The hubs will be repainted along with the brake plates then new linings will be fitted, and bearings. Cheers all, Nigel.
