Still, after more than a century of development, the V-twin still offers the greatest adaptability to the widest variety of roles. For example, the overwhelming majority of customs/cruisers have kept the classic V-twin architecture, just as they have since the first fender was bobbed. In fact, according to Motorcyclist's 2004 Motorcycle Buyer's Guide, 94 percent of cruisers and touring bikes are powered by twins, and 86 percent of those are V-twins. Likewise, more than half the '04 sportbikes, sport-tourers and standard bikes for sale in the U.S. are twins, and some three-quarters of those V-twin-powered. Although displacement, power and torque have skyrocketed during the last century, V-twins have made the most of their inherently relaxed, satisfying cadence as cruisers and tourers.
