With power typically being the product of force and speed, a motorcycle's power and torque ratings will be highly indicative of its performance. Reported numbers for power and torque may however vary from one source to another due to inconsistencies in how testing equipment is calibrated, the method of using that equipment, the conditions during the test, and particularly the location that ...
Split washer or spring lock washer A ring split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener's head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to ...
This secondary spring rate dominates the spring rate of the bolt. Therefore a split lock washer can allow the bolted joint to take the same amplitude of vibration while maintaining more preload, which will result in a joint more resistant to loosening. I know that ASME B18.2.1 2009 does require the lock washer to be trapezoidal in shape.
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.
Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types. The British definition of "cotter pin" may include the equivalent to US term "cotter". To avoid confusion, the term split cotter is sometimes used for a split pin. A further use of the term "cotter pin" is the "crank cotter pin" used to ...
Belleville washer. A Belleville washer, also known as a coned-disc spring, [1] conical spring washer, [2] disc spring, Belleville spring or cupped spring washer, is a conical shell which can be loaded along its axis either statically or dynamically. A Belleville washer is a type of spring shaped like a washer.

The amount of limiting torque provided by these mechanisms varies by design. A limited-slip differential has a more complex torque-split and should be considered in the case when the outputs are spinning the same speed and when spinning at different speeds. The torque difference between the two axles is called Trq d . [8]
