TR280i / Re: Transmission Fluid
« Last post by Lotus54 on November 18, 2017, 09:50:03 PM »
Be aware the oil also lubricates the main bearing.  Most 2-strokes do not do this, although I heard some other trials engines do.

 I have almost 400 hours on my Explorer.  Finally going to pull the head/cylinder and see how the piston is doing. lat I checked (head only) cylinder looked like new and what I could see of piston through exhaust looked really good.

Currently not producing any motorycles.
  They are attempting to start producing again- but who knows if that will ever happen.

They are making electric Bicycles now.

Hello all,
Been trying to find out what the latest state of play is with the ossa factory. Are they really completely out of business now? I bought a 2013 tr280i brand new. No bother at all with it so far, but I can't afford to stock up on s spares for the future....

Hello back from the Highlands of Scotland! I bought a tr280i brand new in 2013. No competing in competitions or the like, just hitting all the local mountains with my mates. Love this bike. Hasn't missed a beat since I got it...
Explorer / Re: 2012 OSSA Explorer for sale $5700

5700 Canadian dollars for my Explorer. It's in very good condition about 25 hours on it. It comes with the 2 Week Diet Marchocci suspension, every thing else is stock. It's missing the front brake lever brake light cable. This hasn't been replaced when broken because it's not street legal in British Columbia.

Nice bike. Do you still have it?

Yes, the master cylinder is a bit difficult to bleed.
  Watch the videos a few times and try it.

I had sort of a system now- and also got a spare master cover that I will install a fitting to pressure bleed. I think that will be better.

Where are you located?

I installed A Clake 2 on my 2016 beta crosstrainer. I kept the rear brake pedal.  I have tried for six months to get the rear brake system bled properly. Any suggestions? Sometimes it pumps up a bit after i ride for awhile but if the bike sits it goes flat.

Explorer / reed valve intake system
« Last post by gianni schena on August 01, 2016, 11:23:16 AM »

I could not find on the manual or other literature who is the maker of the reed valve intake system of the Ossa.

there are two makes around : A) Boyesen Carbon Tech and B) V-Force.

Interesting to know if you have tested both and what you think of them

thank you for your attention , gianni
