2015 Ossa EXPLORER 250Edit
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.
