4.5 Sm Sherco

Improved reliability and efficiency more mature, better finished and more effective. Several new components and a totally new look are the main characteristics of the new 4.5i and 5.1 Enduro and Supermotard models. The motorcycles are more mature, better finished and more effective. The changes and updates are the fruit of an aggressive racing campaign conducted by our racing department and our official factory riders. The teams competed in the Enduro World Championship as well as other prestigious races; the lessons learned in these competitions have been applied to the 4.5i and 5.1i Enduro and Supermotard models. These models have been completely renewed in order to achieve improved reliability, a greater dynamic efficiency and a totally new image. These objectives were achieved through the interaction of the riders and Sherco R & D department. The end result is a motorcycle with a stronger frame, higher quality components, totally new appearance, improved engine management and the ability to choose ignition operating curves. Another notable aspect of the new Sherco's is that the original equipment components are of extremely high quality, similar to what is usually offered in the after market. This is usually not the case with most other brands, this choice of factory installed components guarantees the end user a more efficient and reliable machine from day one.
