Forerunners; the Nîmes technicians were the first to develop a 300cc 4-stroke Enduro engine. A displacement that is now recognized to be the ideal size for the practice of modern enduro racing. Other manufacturers now offer intermediate displacements, however Sherco is one step ahead of the pack with the new 2013 “long stroke” engine which is even better for the application.
REINFORCED SEMI-PERIMETER FRAME
Sherco enduro motorcycles are specifically tailored to the practice of enduro racing.
The use of a semi-perimeter chrome molybdenum frame, is a perfect compromise in order to meet the demands imposed upon it by the variety of terrain that is encountered during an Enduro season. The individual frame sections vary depending upon the forces that will be applied to them. This results in a high lateral stiffness that is optimized in 2013 by double reinforcing the front section and adding additional reinforcement to the shock absorber mount.
The steering precision and turning angle have been greatly improved. The use of Cr Mo enhances the ability of the frame to absorb rigorous shocks and keep the rider comfortable, while maintaining a neutral behavior, which is critical during a long enduro race.
The 2013 Sherco wins again by providing excellent control while maintaining the qualities of the front end that has made its reputation.
The handling and maneuverability have also been improved with a much reduced turning radius. Sherco has performed a lot of work this year to enable the bike to turn tighter, a paramount requirement in modern enduro racing (the fuel tank and the radiator had to be redesigned to provide clearance with the fork tubes).
TOP OF THE LINE COMPONENTS
The components that the Sherco engineers have chosen to use on the enduro models are from the most prestigious names in the industry.
The forks are installed in fully machined triple trees that are made by Neken that are adjustable to fit the ergonomics of the individual rider.
The front brake and clutch controls are entrusted to Brembo. The bikes are equipped with new handguards and a new non metallic skidplate.
” LONG STROKE” DESIGN ENGINE
Already considered by many of the members of the motorcycle press to be the best 2012 enduro engine, the character of the Sherco 300 engine is changing very significantly this year with the adoption of the “long stroke” design.
The “long stroke” design is very suitable for enduro use, it is characterized by a larger reinforced crankcase. It also has a longer stroke but is able to reach high revs.
The 300 has a completely redesigned block, a new crankshaft, new cylinder, new cylinder head with reworked ports, new camshaft, the gearbox ratios have been optimized and the clutch has been lightened.
The exhaust has also been redesigned, the injection settings have been changed to decrease the engine braking.
