Ossa launches an extraordinary model: the new Ossa Explorer 2012. Inheriting the spirit of the legendary Explorer presented in Paris in 1972, the new bike from Ossa maintains its philosophy: A comfortable and very light bike, easy to ride and designed to enjoy both the mountain and trial. . This model will take advantage of the innovative features of the TR280i, such as the two-stroke injection engine and the chassis. This is a style of bike that is not found in the market; a combination of a Trials and an Trail bike. It has a bigger seat and offers fun, safety and comfort, together with amazing handling and inexpensive maintenance. With its ISS Injection Start System, it uses a lithium battery to allow for a precise and easy kick start.

Entirely made in the Ossa GasGas Factory in Girona, the new Explorer brings high technology to a new concept of bike “We know the Explorer is an eagerly awaited bike among Ossa and motorcycling enthusiasts. Apart from a clear tribute to the history of the brand, with this bike we wanted to integrate a high level of technology in this model.
