Sherco 2017 450 SEF-R

The 450 uses the proven formulas from the brand’s low cubic capacity models.

The chassis, while specific for housing the larger motor, maintain the ergonomics of the 300 and 250. The frame is a development of the highly-reputed semi-perimeter Sherco frame in chromium molybdenum steel made of mechanically welded parts. An option selected by Sherco to offer the maneuverability/stability compromise perfectly suited to the highly diverse conditions that may be encountered in the enduro.

Sherco remains loyal to the equipment manufacturers with the best reputations: WP for suspension, Brembo for brakes and TrailTech for the computer (with maintenance indicator). the next generation motor is more compact and higher performance. The timing uses cascading pinion gears an chains. The selector drum is made of aluminium and the valves are steel for greater longevity and extreme enduro use. Power is provided by the Synerject system, developed specifically by Sherco for more precisely governing idling and engine braking, and ensuring perfect progressivity in power delivery…
