  The Harley-Davidson Ultra Classic Electra Glide is part of the "touring" family of Harley motorcycles. These bikes, also called dressers, are made for long distance commutes, as reflected in their well-cushioned relaxed seats, large windshields to block the wind and large fairings. Introduced in 1965, the Electra Glide models are part of the Harley-Davidson FL series, which has been in production since 1941.
  
  

Dimensions

• The 2001 Ultra Classic Electra Glide sported a four-stroke V-twin engine that displaced 88.42 cubic inches. Its bore measured 3.6 inches, and its stroke was 4 inches long. The bore is the diameter of the cylinder where the piston moves, and the stroke is the distance the piston moves up and down.
  
  

Power and Torque

• This engine produced 67 horsepower, or 48.9 kilowatts, at 5,200 rpm. It also produced 110 Nm, or 81.1 foot-pounds, of torque at 3,500 rpm. Torque is a measure of the amount of force it takes to turn an object; this is the force the engine applies to the crankshaft. The rpms refer to the optimal speed of the engine rotation at which these measurements were taken.
