OSSA EXPLORER Models/Series Timeline, Specifications & Photos

The Explorer 280 is powered by a 248cc, 2-Stroke, liquid-cooled, single cylinder engine. With a cylinder bore of 2.85 in and stroke of 2.36 in, its motor is oversquare, meaning that the cylinder bore (width) is greater than the stroke (length). This makes the engine more powerful than one of similar displacement with a smaller bore. The engine is supported by electronic fuel injection which ensures smooth and timely fuel delivery. Electronic ignition makes starting your bike a breeze and ensures a consistent throttle response.

The OSSA Explorer 250 is probably the reference bike in the segment of the trial-tip. To achieve this, they didn’t simply add a “kit” to the base of the TRi but designed an entire subframe, refined ergonomics including a large comfortable seat and specific footrests, and a large fuel tank that, in combination with its efficient fuel-injected engine, provide an excellent range.

The 2015 model gets a new Olle front fork carefully adjusted for the use of the Explorer, along with all the engine and frame optimizations of its trials sister.

When designing the Explorer, OSSA engineers and designers were based on the following approach: create a bike that was easier to reach the most difficult places. Its extreme lightness and trials qualities, combined with its enhanced ergonomics, make it possible to enjoy both tours real quiet as trial areas.

For 2014, the Explorer receives multiple internal and external improvements. The engine has been thoroughly revised to improve reliability and further refine its operation, while in the cycle have polished practical details that make the experience even better to ride an Explorer.
