All the characteristics and improvements of the 2006 4.5i are also found in the "big" Sherco. The 5.1i has a cylinder displacement of 510 cc; the only changes to the engine from the 4.51 are in the bore and the stroke. This required a new cylinder, piston, connecting rod and crankshaft.
This motor is very manageable and continues the Sherco philosophy which requires that the motor be very adequate for the amateur enduro rider. The plan is to provide the rider with a motorcycle that has such usable power that it will not break the arms of the rider in a two minute excursion. A motor that is so tractable that one could almost ride it in a trial.
As is the case with the 4.5i, the riding position is very natural on the 5.1i. For such a large displacement motorcycle it has incredible maneuverability.
With the addition of the Sherco 5.1i, to the extensive line up of Sherco Enduro Models there is good reason to believe that there is a bike that will meet the needs of everyone who is a follower of the Sherco brand.
