For this season, Sherco has concentrated on improving many details on the 4.51. We have listened to our dealers and our customers around the world and have made the changes they requested. Sherco has refined this model in order to provide the quality, features and reliability that will propel it to the top of its class.
The changes in the motor begin with better transmission ratios for 2nd and 3rd gears, new valves for improved power, a revised fuel injection curve for an even more smooth and powerful engine and a new lighter flywheel for improved engine response. The automatic de-compressor has been totally redesigned in order to improve reliability and function.
In the suspension area the rear Paioli shock absorber has been shortened which allows the seat height to be lowered 2.5 cm with out having any adverse effect on the handling of the bike, which was deemed to be outstanding in the 2005 model.
Many other significant new features have been added to the Sherco 4.5i which are mentioned in the following section.
