The 1450-cc Harley Twin Cam 88 engine is rated to produce 80 horsepower at 5200 RPM, and 82 foot-pounds of torque at 3500 RPM.
Harley Davidson has been improving its Big Twin engines since the first side-valve 74-cubic-inch engine was introduced in 1922. The Big Twin series has progressed through the Knucklehead, Panhead, Shovelhead and Evolution engines to the Twin Cam series, which was produced from 1999 to 2006.
While Harley riders usually prefer the design of their first personally owned Big Twin, they generally concede that each progressive redesign has been an improvement over previous designs.
The Twin Cam 88 has a cylinder bore of 3.75 inches and a piston stroke of 4 inches, rendering a displacement of 88.4 cubic inches or 1449 cubic centimeters. This is an increase in bore size, but a decrease in stroke compared with the previous 80-cubic-inch Evolution engine’s 3.5-inch bore and 4.25-inch stroke.
