I see it is a website for a manufacturer. Do they sell OSSA gearbox parts as well?

PM me your email

Here are some pics of the gearbox for those interested. What a neat setup.

My understanding is they didn’t really merge with GasGas, but they did have a production and parts distribution agreement. So when GasGas went under, they no longer had a factory or warehouse. Of course, the story I was told is the whole reason to do this agreement was to save money, secure more loans and both companies to keep afloat. So I assume OSSA was barely afloat anyway. I have communicated withe the ‘owner’ that has claimed several times to ‘be ready for production soon’- of course that didn’t happen. I did see they were making bicycles, but I do not know what has happened with that. personally, I’m disappointed it could not keep producing bikes. I found them to be excellent (a bit of teething issues at first). For my use, I would have liked a little more robust suspension linkage setup and a better ‘easy start’. Interestingly, the 2012 Explorer I have in my shop right now has a little battery- so fuel pump runs when the key is turned on. Makes it easier to start I think (like my ‘super easy start’ setup). But indeed- they have not produced bikes since the 2015 model as far as I’ve been able to determine. And no, not at all like the 1970 model, in name and place of construction only.

Well, I sold my 2014 Explorer last week. I really have liked that bike- LOTS. It has been pretty darn good, with the linkage the weak spot for how I was using it. If they had a more robust linkage with real bearings, I think it would be a LOT better. No engine problems at all, just a broken return spring for the gearbox. I had no plans to sell, I even bought a Beta 4T to ride so I would not put so many hours on it. But most of my buddies ride enduro bikes, so after getting a Beta Xtrainer, I found I just wasn’t riding the Beta 4T trials much. So I sold it. Someone was interested in the OSSA- and I decided to give electric a go. Electric-Motion has a model with a real clutch now, so I ordered a version with that. That may work out well for the type of use I’ll likely do know with having the XTrainer. I really needed to sell a couple of bikes to pull it off- and figured it was time to try something new. I will sure miss the OSSA, what a wonderful bike. I would sure like one just a bit more robust for trail riding- oh and fix that phony fuel cap! I still work on the OSSAs, so I’ll still be around.

Send me your email (PM here is fine) and I’ll get you the software. There is a couple of threads about building them- buying is pretty expensive now that the supply of the BTWICE ones dried up. (That is what I have).

I have a customer 2012 Explorer (with fixer nut). It was stuck in 6th, I popped out the gearbox and found a broken gear. 6th drive gear tooth/engagement dog if I have it right. It appears on 6th the teeth just extend out to make an engagement dog. Not very thick there so seems a weak spot? But I always tell people to shift this slowly and gently and they will last great. Start ‘jamming gears’ like an enduro bike and you could probably break it in an hour. I had almost 400 hours on my Explorer (just sold it)- only gearbox issue was a broken return spring. Edit: Dang, I forgot the original reason for post. Who has gearbox parts? I have a call into Lewisport, but no answer back yet. I’m in the States.

Do you have the software and cables? First set idle speed, then with the software set TPS to .6V (move the TPS until the software reads .6)- THEN ‘set to ECU’ with software (button). This will make a huge difference if off. I found with mine I had to reset TPS about every 100 hours to keep it happy. The never versions also have a base setting adjustment Plus/minus from 100% I’ve made the cables, pretty easy to build. Parts can take time to find source, but no big deal.

This is from another thread- but shows the real clutch on the epure race. I believe the motor shaft has a gear on it that drives the clutch, much like a ‘traditional’ bike. I don’t know how much the flywheel weighs are, but it appears three different options?

After fitting my ‘super easy start’ setup, I found the bike was a lot easier to kick. It did not seem to need as hard a kick as stock. (I put a tiny LiPo battery with momentary switch (kill button) to apply 12Vdc to the diagnostics connector )

Do you mean a completed cable? Or just the parts to build one. I got the USB TTL interface cable from Elmwood electronics, but I’m sure they are available in Europe.

Well I finally got around to making up a spare diagnostics cable. I have BTWICE one, but got the USB TTL interface a couple of years ago to make some more. I used another user here (darn if I can remember name right now) for the TX/RX and ground pins (already knew power from battery ones). Worked great! I tested my BTWICE first, then the one I made. I had to pick a different COM port that matched to the new cable I made, but the driver I had worked great. I see where you can download drivers for the USB interface I used also. I was running under Win7, reset the TPS and a few other tests. I did not try loading new maps with it though- but I expect it will work just fine.

I did some searching, but didn’t see any answer. Is there any sort of Service Manual available for the Vertigo? software for the FI with diagnostics etc?

From what I could tell by the EM site and a video I saw on it. The clutch is after reduction. Flywheel with different weights is on the end of the motor. Clutch does have oil. I’ll see if I can find the site showing that.

I tried sending you a message- but you cannot accept them? Send me your email and I’ll send you a working link

I was thinking the Explorer just had extra connections for the lights/turnsigs/brake lamps etc. I have an Explorer, but I don’t think I have ever seen an Explorer specific diagram. what part are you needing info on?

My bikes seem very sensitive to Spark plugs. I would replace it, even with the low hours. I had to go up a heat range too, the stock was too cold.

I have tried a few different maps, I forget which one is in there now- for my Explorer I think the latest 280, I never got around to doing a map switch, so the dual maps that could be quite useful for me I’ve not really tried. I think my (now sold) 300 factory had the latest 300 termi map. this is that bike, had not been started in 3 or 4 months I think. you can hear the fuel pump run when I push the ‘super easy start’ button I added (full 12V to fuelpump/ecu etc)

Did you get the software? There has been a few postings on how to build a lead. I have the parts to do so, but have not made time to do it (I already had one)

Yes, the Factory 300 I had (recently sold) had the Termignoni exhaust. I have a Beta 4T 300 factory also, it is much, much ‘calmer’ than the OSSA. But it also weighs quite a lot more (about what my OSSA Explorer weighs). I thought the Beta was quite similar in reaction to the Explorer. I don’t remember what the Beta has for a throttle.

As a note, the 300 Factory I owned was VERY aggressive. I used the ‘slow’ map switch position, changed to slow throttle and installed one tooth larger countershaft sprocket to tame it down for my ‘intermediate’ skills. I am not sure how much difference between the factory and standard 300 models.

Thanks, it does look like the FD460 or EBC shown

Anyone know what other bikes use the same front brake pads as the 15 Factory 300? They do not have locating pins, but rather rounded areas that lock into the caliper.

The bushes I’ve seen have part numbers on them from the manufacturer (Not OSSA). I source them that way and buy them by the 10 pack. I ride in mud a lot and they don’t last long. I have one of the Titainium linkage setups on my Explorer, and it has zerk fittings so I can push fresh grease (I use silicone/teflon) through and (hopefully) push out much of the mud. That helps a lot.

I emailed you. glad to help.
