Motorcycle wrapped in leather

MILWAUKEE--The Harley-Davidson Museum's Collection X assembles the stranger exhibits from the history of motorcycles and biker culture, including rare motorcycles, artwork, prototypes, concept designs, and machines that managed extreme driving feats.

CNET got to visit Collection X, which will be on display through August 22, during a recent trip to the Milwaukee area to tour both the Powertrain Operations factory and the Harley-Davidson Museum.

A highlight of Collection X is the 2000 Red Moon Evo Chopper. Twenty Japanese artists took two years to hand-stitch fine warm-hued leather over every inch of this high-handlebar motorcycle, including engine parts.

Captain America's vintage Harley

Harley-Davidson built motorcycles for America's war effort in the 1940s. It's only natural to assume the legendary Captain America would have had his own armed bike as he carried his shield into battle against the Red Skull.
