• Choppers: Highly customized motorcycles based on a cruiser-style frame with long rake (longer front forks) and wild paint jobs. Many are created more for show than rideability.
• Cruisers: A range of small to large motorcycles designed for comfort and looks with a relaxed upright or reclined seating position. They often use lots of chrome and may be highly customized.
• Electric motorcycles: Nearly silent, zero-emission electric motor-driven vehicles. Operating range and top speed suffer because of limitations of battery technology. Fuel cells and petroleum-electric hybrids are also under development to extend the range and improve performance of the electric motors.
• Mini bikes: Very small bikes designed to be simple run-around fun for both children and adults. Generally they have no hand-operated clutch or gearbox to simplify operation. Also known as Mini Motos. .
• Mopeds: Small, light, inexpensive, efficient rides for getting around town. Usually started by pedalling (motorcycle + pedals = moped).
• Naked bikes/Standard/Street bikes: Naked bikes have a riding position midway between the forward position of a sports bike and the reclined position of a cruiser. Unlike touring bikes, naked bikes often have little or no fairing (hence the title).
• Scooters: Motorbikes with a step-through frame, generally smaller wheels than those of a traditional motorcycle and an engine mounted near the rear wheel on the swingarm.
• Sport bikes: Fast, light, sleek motorcycles designed to give maximum performance for racing or spirited road riding while conforming to FIM rules. They are distinguishable by their racing style fairings and the rider's tipped-forward seating position. They are also called "race replicas" because of their connection to the racing category for production motorcycles known as Super bike racing, and earlier similar race series (the term arose in the 1980s). The power to weight ratio of the 900 cc+ models typically matches or exceeds one bhp of power for every one kg of mass.
• Racing bikes: Motorcycles designed for circuit or road racing, including mass-production motorcycles modified for motorcycle racing or sport riding.
• Street customs: Highly customized motorcycles with wild paint jobs also built for show, but constructed from a sport bike frame instead of a cruiser-style frame.
• Touring motorcycles: Touring bikes are designed for rider and passenger comfort, luggage carrying capacity, and reliability. Cruisers, sport bikes and some dual-sports can also be used as touring bikes with the addition of aftermarket luggage and sometimes seats. Common throughout the touring market are usually large-displacement fairings and windshields (for weather and wind protection), large-capacity fuel tanks (for long-range travel), engines optimized for progressive torque rather than highest possible power, and a more relaxed, basically upright seating position.
• Sport touring motorcycles: Sport-tourers combine attributes of a sport bike and a touring motorcycle. They are built for comfortable long-distance travel while maintaining a forward-leaning riding position, good handling, and high performance.
• Underbones: Small motorcycle which is a crossover between a scooter and a true motorcycle with step-through frame, popular in Southeast Asia. While the fuel tank for most motorcycles are tear-shaped and located at the top and just behind the instrument panel, the fuel tank for an underbone motorcycle is located under the seat.
