  • After Market
    Items or accessories that are not from the Original Equipment Manufacturer.
  • Air Cooling
    Air cooling is a method of dissipating heat from an engine to keep it at operating temperature. It works by making the object to be cooled have a larger surface area or have an increased flow of air over its surface, or both.
  • Alternator
    An alternator is an electromechanical device that converts mechanical energy to electrical energy in the form of alternating current. Most alternators use a rotating magnetic field but linear alternators are occasionally used. In principle, any AC electrical generator can be called an alternator, but usually the word refers to small rotating machines driven by automotive and other internal combustion engines.
  • AMA - American Motorcycle Association
    The AMA is the largest motorsports organization in the world, overseeing 80 professional and more than 4,000 amateur events each year. The AMA also maintains the Motorcycle Hall of Fame located near Columbus, Ohio. It is the designated governing body of motorcycle sport in the US by the world governing body, the Fédération Internationale de Motocyclisme (FIM).

  • Belt Drive
    A belt is a loop of flexible material used to link two or more rotating shafts mechanically. Belts may be used as a source of motion, to transmit power efficiently, or to track relative movement.

  • Cafe Racer
    A café racer, originally pronounced "caff" (as in Kaff) racer, is a type of motorcycle as well as a type of motorcyclist. Both meanings have their roots in the 1960s British counterculture group the Rockers, or the Ton-up boys, although they were also common in Italy, Germany, and other European countries.
  • Cager
    The driver of a car, truck, van, or other vehicle that has a frame or structure that resembles a protective cage. For example, a car's structure surrounds the driver, whereas a motorcycles structure does not.
  • Camshaft
    A camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part.
  • Carbon Fiber
    Carbon fiber, alternatively graphite fiber, carbon graphite or CF, is a material consisting of extremely thin fibers about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber very strong for its size. Several thousand carbon fibers are twisted together to form a yarn, which may be used by itself or woven into a fabric. Carbon fiber has many different weave patterns and can be combined with a plastic resin and wound or molded to form composite materials such as carbon fiber reinforced plastic (also referenced as carbon fiber) to provide a high strength-to-weight ratio material. The density of carbon fiber is also considerably lower than the density of steel, making it ideal for applications requiring low weight.

  • H

  • Horsepower
    A unit that is used to measure the power of engines and motors. One unit of horsepower is equal to the power needed to lift 550 pounds one foot in one second. This unit has been widely replaced by the watt in scientific usage; one horsepower is equal to 745.7 watts.

  • Ignition Timing
    Ignition timing, in a spark ignition internal combustion engine, is the process of setting the time that a spark will occur in the combustion chamber (during the compression stroke) relative to piston position and crankshaft angular velocity.
  • Inline
    Engine layout in which the cylinders are arranged in a row. For example, an “inline 4″ engine would have 4 cyclinders aligned in a row.
