Standard / Naked
This is the basic form of the motorcycle stripped down to its fundamental parts.
This style of motorcycle became the "norm" in the 1970s and early 1980s (with the advent of the Universal Japanese motorcycle), but fell out of favour as motorcycles evolved and niches developed for sport, touring, and cruising. The "naked" saw a resurgence at the end of the 1990s, driven in large part by the European market, with many manufacturers releasing new models with minimal or no fairings. Current naked bikes are usually given a modern, more-or-less sporting suspension, unless they are intended to have "retro" styling. The Ducati Monster, Triumph Speed Four, and Suzuki SV650 are popular examples of naked motorcycles. Large engine displacement versions of naked motorcycles, especially those built in Japan, are often referred to as "muscle" bikes, for example: Honda CB 1300 Super Four, Suzuki Bandit 1250.
