OSSA

I just received my new OSSA explorer! first 2014 in the country! Great looking bike, lots of interesting and neat details. Once I was told how to use the 'easy start' it fires right up. Air filter is really easy to service, good access for most stuff from what I ca see. I like the under seat storage and simple key remove seat. Clutch felt great, brakes work well with lots of feel. Seems very smooth progressive power. I have ridden it much yet, so I'll tell more later. I'll have to raise the bars for the riding I'm doing with it (standing all day)- but everything else feels pretty darn good. I'll post up some reviews as I get some time on it.

Having a few issues with rear wheel alignment on my MK1 MAR Does anyone know the length of the original spacer between the sprocket and swingarm please - this is the original dished sprocket with the longish spacer I've now fitted a new dished sprocket on a newly built wheel in place of the old flat conversion but the spacer is long gone. Normally I'd just measure the gap and make the spacer but I've an added problem. The wheel that came out of the bike was the original MK1 with thinner brake shoes but it had some damage. The wheel I've rebuilt is a MK2 with the wider shoes and the MK1 brake plate won't fit (I'd forgotten there were differences and the brake plate for t…

Hi, I am looking to get a spare rear wheel for practice but haven't seen much online. I have seen gas gas, beta, etc and was wondering if anyone knew if any of these other wheels would do the job? Thanks in advance...

any one know were i can get 2 x fifth gears to suit ossa phantom????

Looking for tips and tricks for 2010-2015 Ossa TR’s. I just bought a 2015 TR250I and am in the process of going through it, replacing worn out parts. Thanks to a local parts supplier, so far it’s going pretty good. Biggest issue I’ve ran into was the silencer had a broken bolt stuck in the aluminum and a broken bracket on top for a clip type nut.

I’m looking for a headlight reflector for my 78 VI Day. I’m not sure but I believe it was only used on the 78 black tank VI Day. I haven’t been able to find one anywhere. I’m hoping someone on this site knows of a source. Thanks

I have a 1974 MAR 250 with standard Motoplat stator (red. No battery) How do I wire the lights? I have Red, Green, White, Blue, and black wires. Sid

Hi there guys,well i finally have my new 2012 TR280i in the garage,if it ever stops raining i will be able to take it for a ride.Anyway getting to the chase,i went to remove the rear wheel for a wee look and check the axle for lube,drooped the chain,removed the axle and proceeded to slide the rear wheel back and what do you know,the heads of the rear disc bolts catch the inside of the calliper assembley, am i missing something here,i have had many bikes over the last 30 years but have not had this before,surely you dont have to remove some disc bolts first? Peter.

Hi i am trying to contact the owner of a ossa with registration number AE12GXW who rode the lakes two day, please can you pm me with a contact number, i have some bits of yours

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.

My uncle has a 2011 ossa 280, the clutch is very heavy and really spoils the bike, i previously had the same year bike and mine was lovely and light, same as other bikes. Is there a way of lightening it, maybe removing a couple of springs?

Hi guys. Got a 2012 Ossa TR280i for a price i could not say no to. I'm a bit worried about parts, and already want to order me a new rear fender as i am pretty sure I'm going to break the one on the bike eventually. Where can one order Ossa bits these days?

Disclaimer; As a newer novice rider I am painfully aware that this bike is way, way more bike than I need or can make proper use of. To be honest, I just don't care, the more I learned about it the more I felt like I had to have one. I will keep riding and I will keep getting better. I am a huge technology junkie and I really appreciate the engineering I see on this bike. You folks here seem to like them plenty, I have a few questions. This bike is supposedly a limited edition as well, does that mean anything at all or are all 'factory' models limited editions? What upgrades does the factory version have that the regular bike does not, is it lighter, how much? 300…

Well, just learned of another delay in my Ossa Factory delivery...recall on the main bearing. I'm now on near 3 months delay. So the importer is going to have to uncrate the bikes, repair, recrate, then ship to the dealer. I'm assuming another month or so...assuming the importer gets the parts quickly. So I'm getting a model '14 bike well into the 2015 year...all at a premium price...IF there are no further delays. So... 1. Is The bike worth the wait? 2. Is Ossa healthy financially...seems there have been numerous delays at the factory? The Importer has never made promises...just given me ETA's. Yet Ossa has constantly had issues in manufacturing....not exceed…

I have an Amal carburettor with the number 627 cast into it and 429 stamped into it. Is this the standard mar carburettor? The main jet is a 140 and the needle jet is a 106. Are these somewhere near correct? My new (to me) mar has apparently come from Italy if that might make a difference

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 Thanks for your help so far with my TR77 restoration. Today I got the top end on, the timing done, a spark, and most of the parts left ready to bolt on (waiting for a pushrod oilseal and the paintwork to come back). I'm sure that I'll be asking for more help, but here is the bike as of tonight. :-)

Hi. For those who want to know how to disassemble the gearbox, the pinion must be heated to about 200ºc. Now I'm going to change the bearings. They are references of Gasgas. MT280236158 MT280232043 Cheers.

Hi everyone. I'm new to twin shock trials and having ridden a few borrowed bikes I'm now ready to look at buying my own bike. I'm being drawn to the Ossa Mar and would like to know if this bike would be suitable? I'm 49yrs old 5ft 6 tall Weight is 9 1/2 stone All comments welcome Thanks
