7. Ossa Explorer

Explorer was an Ossa model from nearly 40 years ago the company is reviving for 2012. The Explorer bridges the gap between trials bike and MXer, with an intention by the Spanish manufacturer to be used on narrow, single-track trails littered with technical sections. The Explorer is powered by 272cc, dual-injected two-stroke engine and is said to weigh just 164 pounds dry. Production is scheduled to begin in February. No word on U.S. availability.
