The comparison of mean piston speed (black line) with real piston speed (color lines). Diagram shows one stroke from BDC to TDC. Revolution = 1.000 min-1, stroke = 88 mm. The connecting rod ratio l/r varies: 3 - red, 4 - green, 5,5 - blue. The mean piston speed is the average speed of the piston in a reciprocating engine. It is a function of ...
While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range [1] (electric motors are an exception—see the section on electric motors below). Specifically, power band is the range of RPM around peak power output.
A Triumph Sprint ST on a chassis dynamometer Suzuki Hayabusa at Bonneville Speed Week.. Motorcycle testing and measurement includes a range of more than two dozen statistics giving the specifications of the motorcycle, and the actual performance, expressed by such things as the output of the engine, and the top speed or acceleration of the motorcycle.
A Suzuki GSX-R1000 at a drag strip – a 2006 model once recorded a 0 to 60 mph time of 2.35 seconds. This is a list of street legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1 ⁄ 4-mile times of under 12 seconds.
The fastest production motorcycle for a given year is the unmodified motorcycle with the highest tested top speed that was manufactured in series and available for purchase by the general public. Modified or specially produced motorcycles are a different class, motorcycle land-speed record .
Tachometer showing red lines above 14,000 rpm.. The redline is the maximum engine speed at which an internal combustion engine or traction motor and its components are designed to operate without causing damage to the components themselves or other parts of the engine. [1]
The valve is a slightly oval shape. This changes the height and size of the exhaust port at different engine speeds, maximizing the available power at all rev ranges, opening up firstly at 3k rpm for low end power, gradually in between 3-6k, fully opening at 6k rpm for maximum power, on most 125cc.
Motorcycles with a V-twin engine mounted with its crankshaft mounted in line with the frame, e.g. the Honda CX series, are said to have "transverse" engines, [1] [2] while motorcycles with a V-twin mounted with its crankshaft mounted perpendicular to the frame, e.g. most Harley-Davidsons, are said to have "longitudinal" engines.
