After its first year in the enduro market, Sherco presents several new features for the 2006 season. In the past six years Sherco has proven to the world that they are a manufacturer of leading edge off-road motorcycles. The models presented here are no exception. The effort has not been in vain, in these six short years Sherco has created a complete line of Enduro and Trials Motorcycles with more than 16 available models and several more under development including the new 2.5i. During the next 9 months Sherco will revise all of their existing models with completely new Trials and Enduro models in the 50cc and 125cc class. These bikes will be ready to be shown at the next Paris Motorcycle Exposition thus showing the tremendous amount of activity that has been generated by the Spanish-French firm.
Sherco 4.5i 2006:
Refined and even more Reliable 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.
