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.
For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
The airtightness of buildings is measured at 50 Pa. [15] In medicine, blood pressure is measured in millimeters of mercury (mmHg, very close to one Torr). The normal adult blood pressure is less than 120 mmHg systolic BP (SBP) and less than 80 mmHg diastolic BP (DBP). [16] Convert mmHg to SI units as follows: 1 mmHg = 0.133 32 kPa. Hence the ...
A dual seat, typical of most modern motorcycles. A motorcycle seat (sometimes saddle) is where rider sits, and may also accommodate a passenger. The most common type of motorcycle seat is a dual saddle or bench seat, which runs along the top of the chassis and is long enough for a pillion passenger to straddle the motorcycle behind the rider ...
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase , steering axis angle, fork offset, and trail.
Automotive engineering, along with aerospace engineering and naval architecture, is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software, and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles, and trucks and their respective engineering subsystems.
In the cgs system the unit of pressure was the barye (ba), equal to 1 dyn·cm −2. In the mts system, the unit of pressure was the pieze, equal to 1 sthene per square metre. Many other hybrid units are used such as mmHg/cm 2 or grams-force/cm 2 (sometimes as kg/cm 2 without properly identifying the force units). Using the names kilogram, gram ...
The BMW R1200C was a cruiser motorcycle made by BMW Motorrad from 1997 to 2004. BMW manufactured 40,218 units, including a smaller engine version, the R850C, which was produced from 1997 to 2000. [1] The R1200C was BMW's attempt to tap into the cruiser market. The R1200C was designed by BMW head designer David Robb, with a cruiser riding ...
