Heritage Summary:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer renowned for its V-twin engines and cruiser styling. The brand has a long history of innovation and cultural impact.
Softail Lineage:
The Softail platform, introduced in 1984, is designed to mimic the appearance of a hardtail frame with concealed rear suspension for a classic look and modern ride comfort. The FLSTN ('N' denotes Nostalgia) variant specifically evokes vintage styling.
Deluxe Styling:
The Deluxe model features a classic, retro aesthetic with ample chrome, a low seat height, wide handlebars, and often whitewall tires, reminiscent of motorcycles from the 1940s and 1950s.
Production Period:
The FLSTN Softail Deluxe has been produced in various forms since the early 1990s. The 2008 model represents a specific iteration within this long-standing model line.
