Twin Cam 96 Harley Davidson Engine

The Harley Davidson Twin Cam 96 is an air-cooled, push-rod operated,
45 degree engine with two cylinders in a V-twin configuration that
first appeared on Dyna, Touring, and Softail motorcycles in 2007. This
engine was the successor to the Harley Davidson Evolution engine and at
present is used to power Dyna and touring models.

The counter-balanced Twin Cam 96B engine was also seen for the first
time in 2007 and is currently used to power all Softail models. This
engine was redesigned for the Softail motorcycle to produce less
vibration (a problem with the standard Twin Cam 96).

The Twin Cam 96 engine was redesigned to include 700 new parts when
it first appeared in 2007. They made changes to the crankshaft,
connecting rods, crankcase, transmission case, and all transmission
parts.  The Twin Cam 96 redesign resulted in an engine that produced 17
percent more torque than its predecessor.  They also added Electronic
Sequential Port Fuel Injection  and a 6-Speed Cruise Drive transmission
with a helical cut 5th gear that made shifting smoother and decreased
transmission noise.

The power and performance numbers for both versions of the Twin Cam
96 engine are about the same, with each producing about 92 ft lbs of
torque @ 3000 rpm.
