2018 300 SEF SIX DAYS

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. It shines in every area and is a treat to ride whether it is tight single track or a fast flowing open course. The 300 cylinder displacement provides muscular torque combined with a pleasing vivacity. It is the perfect compromise for the average rider!
