Technology / Motorcycle / Crankshaft: The main rotating shaft running through the length of the engine. As the pistons move up and down, they work together to spin the crankshaft. The rotating motion of the crankshaft is transmitted to the gear cluster which is eventually used to rotate the rear wheel of the motorcycle.


Technology / Motorcycle / Camshaft: A metal shaft with two or more cams (oval "lobes") that rotates to operate inlet and/or exhaust valves in a four-stroke engine. MORE


Technology / Motorcycle / Pushrods: Pushrods are used to connect to rocker arm assemblies which, in turn, open and close valves. In this case, the Camshaft is located near the crankshaft. The rotation of the camshaft causes its lobes to MORE

Big End

Technology / Motorcycle / Big End: The larger (crankshaft) end of the connecting rod. MORE

Vanadium (V)

Science / Periodic Table of Elements / Vanadium (V): Atomic number: 23, Atomic mass: 50.9414 g.mol -1, Electronegativity: 1.6, Density: 6.1 at 20°C, Melting point: 1910 °C, Boiling point: 3407 °C, Vanderwaals radius: 0.134 nm, Ionic radius: 0. MORE

Flat Twin

Technology / Motorcycle / Flat Twin: A two cylinder internal combustion engine with the cylinders arranged on opposite sides of the crankshaft. The best known example is the "traditional’ (since 1923) BMW motorcycle engine, where it is MORE

Bottom End

Technology / Motorcycle / Bottom End: Bottom End refers to the bottom portion of a motorcycle engine including the crankshaft, connecting rods and bearings, primary chain, cam sprockets, seals, and other components that support delivering MORE
