Sport bikes have comparatively high performance engines supported within a lightweight frame. Sport bikes are road bikes which emphasize top speed, acceleration, braking, handling and grip, typically at the expense of comfort and fuel economy in comparison to other motorcycle types. Cruisers have limited cornering ability due to a lack of ground clearance. At low to moderate speeds, cruisers are more comfortable than other styles, but riding for long periods at freeway speeds can lead to fatigue from pulling back on the handlebars to resist the force of the wind against the rider's chest. The riding position places the feet forward and the hands are up relatively high, so that the spine is erect or leaning back slightly. Their engines are tuned for low-end torque, making them less demanding to ride because it is not necessary to shift as frequently to accelerate or maintain control. Harley-Davidsons largely define the cruiser category, and large- displacement V-twin engines are the norm, although other engine configurations and small to medium displacements also exist. Harley-Davidson cruisers and a touring bike (red)Ĭruiser motorcycles (or simply cruisers) are styled after American motorcycles from the 1930s to the early 1960s, such as those made by Harley-Davidson, Indian, and Excelsior-Henderson. Due to their flexibility, lower costs, moderate engine output, and up-right seating position, standards are particularly suited for beginner motorcyclists. Footpegs are below the rider and handlebars are high enough to not force the rider to reach too far forward, placing the shoulders above the hips in a natural position. Standard is often a synonym for naked, a term that was originally used in reference to 1950s road racing bikes. Standards are typically not equipped with fairings or windscreens from the manufacturer, hence the name naked bikes. They are characterized primarily by their upright riding position (in-between the reclining rider posture of the cruisers and the forward leaning of sport bikes) and most of the usable torque (powerband) at lower engine rpm for commuting and fuel efficiency. Standard motorcycles (also called naked bikes, roadsters, or simply standards) are motorcycles mainly intended for use on streets for commuting. Street motorcycles powered by electric motors are becoming more common, with firms like Harley-Davidson entering the market. Typically, street motorcycles are capable of speeds up to 100 mph (160 km/h), and many of speeds in excess of 125 mph (201 km/h). They have smooth tires with tread patterns and engines generally in the 125 cc (7.6 cu in) and over range. Street motorcycles are motorcycles designed for being ridden on paved roads. Some experts do not recognize sub-types, like naked bike, that "purport to be classified" outside the six usual classes, because they fit within one of the main types and are recognizable only by cosmetic changes. There are also informal classifications or nicknames used by manufacturers, riders, and the motorcycling media. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or legal definitions of a motorcycle established by certain legal jurisdictions for motorcycle registration, emissions, road traffic safety rules or motorcyclist licensing. There is no universal system for classifying all types of motorcycles. Scooter, moped, underbone, miniature, pocket, electric, and three-wheeled motorcycles are generally excluded from the main categories but other classification schemes may include these as types of motorcycles. Strong distinctions are usually made between the six main types of motorcycles and other motorcycles. Īlthough there are many names and systems for classifying types of motorcycles based on their characteristics and usage, there are generally six categories recognized by most motorcycle manufacturers and organizations.
Sport touring is sometimes recognized as a seventh category or integrated with the touring category. The six main types of motorcycles are generally recognized as standard, cruiser, touring, sports, off-road, and dual-purpose. A group of sport bikes, cruisers, scooters, and touring bikes
