The Perfect Balance

The Sherco 300 4-stroke has an unrivaled reputation. An atypical displacement, it has convincingly proven to all enduro riders and magazine test riders that it is an absolutely amazing machine.

A pioneer in the 4-stroke enduro middleweight class, it can do everything demanded of it. From the casual rider to the professional racer it is an effective tool.
