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.
