  Part of the Softail group of motorcycle cruisers built by Harley-Davidson, the Night Train was only sold to the European market. Born in 1998, the bike got a fuel injection system in 2002 and a boost to a 1580cc engine in 2006. In 2009, the last version of the bike was produced.

Engine

• The 2009 Night Train has a 1,584cc engine (the figure refers to the volume inside the cylinders that is swept by the pistons). It is a V-twin, meaning it has two cylinders arranged at an angle to each other. It has two valves per cylinder. The engine is a four-stroke, which means the pistons take four strokes to complete an engine cycle. The 2009 Night Train's motor -- called a Twin Cam 96 -- produces 87.9 ft-lbs of torque.

  The Night Train engine has a bore and stroke of 3.75 by 4.38 inches and a compression ratio of 9.2 to one. The bore is the diameter of the engine cylinder opening and the stroke is the total distance the piston travels up and down. Compression ratio is the ratio of the volume between the piston and cylinder head before and after a compression stroke.

Transmission and Suspension

• The Night Train has a chain final drive system to transfer engine power to the rear wheel, and six manual speeds. The front suspension of the bike uses telescopic forks, and the rear suspension uses a steel twin swing arm. The brakes on the Night Train are both 11.5-inch-diameter discs. A disc brake is a metal disc fixed to the wheel. When force is applied by pulling on the brake lever, a caliper pushes brake pads against the disc, causing friction and slowing the wheel.
