The OSSA Enduro

After the first presentation of the Ossa TR 280i prototype in Milan, a new development work began before the production of a really new revolutionary bike. Two years later, Ossa Factory has chosen again the EICMA show to present a new prototype that will stand out in the enduro discipline. The Ossa Enduro is born with a large work experience and incorporates some novelties to get a lightweight and maneuverable bike with a brilliant engine.It’s a bike with innovative features that once again make a difference and keep Ossa Factory’s philosophy: to provide the market with atechnologically advanced product with lots of advantages such as performance, and the possibility to tune and adapt it to the requirements ofevery riding style.

The new Ossa Enduro 250i/300i recovers the idea of the 70’s and it emphasizes an adventurous design and a compact motorcycle. Within itscharacteristics, the most relevant are a revolutionary two-stroke engine, a perimeter chassis and a new position of the air box.


If the Ossa TR280i revolutionized the trials discipline, the new Enduro 250i/300i appears with the same spirit but with the advantage of all theexperience Ossa Factory’s team has gained in the past years. The separable chassis of the new Ossa Enduro 250i/300i made of cromoly,has a perimeter structure and the fuel tank is not part of it, but it is placed in a lower and forward position. The particularity is that the air filter boxhas been placed inside so that it is protected by the cover of the fuel tank. The premium quality suspensions are from Öhlins, a brand with which OssaFactory has an interesting cooperation. The position of the rear shock on the right side allows for extra space to fit a part of the exhaust pipe. Thisshock works with a progressive linkage system assembled onto tubular swingarm.The inverted fork has 48mm stanchions and the 260mm disc on the front and 220mm on the back with Brembo callipers ensure powerful and safe braking.


The two stroke engine with a one-piece crankcase and removable gear assemblyof the Ossa Enduro 250i/300i features a new and revolutionary double injectionsystem designed in association with Kokusan and an electronic exhaust valvewhich is controlled by the same ECU as the injection.One of the injectors is situated on the crankcase and the other on thecylinder. This is rather unusual as it is normally placed on the cylinder head, but this new system offers amazing possibilities to fine-tune the bike response.
