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.
A Sokół 1000 V-twin engine. Engines with more cylinders for the same displacement feel smoother to ride. Engines with fewer cylinders are cheaper, lighter, and easier to maintain. Liquid-cooled motorcycles have a radiator which is the primary way their heat is dispersed. Coolant or oil is constantly circulated between this radiator and the ...
"Cutaway of Yamaha Genesis inline-four 20-valve engine" The DOHC Genesis engine has five valves per cylinder and downdraft carburetors. Yamaha adopted the 5-valve concept, using three intake valves and two exhaust valves per cylinder, because it allowed both excellent volumetric efficiency and high RPM. As designers began to appreciate the ...
A Honda Super Cub engine. The most popular motorcycle in history, with over 100 million produced. A motorcycle engine is an engine that powers a motorcycle.Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
The Yamaha XS Eleven motorcycle, also called XS 1100 and XS 1.1, is a Japanese standard produced from late 1977 (MY1978) to 1983, powered by an air-cooled 1,101 cc (67.2 cu in) 4-stroke, DOHC inline four-cylinder engine mounted transversely in a duplex cradle frame with swingarm rear suspension, shaft drive, and telescopic forks.
Prior to the late 2010s, forced induction was only used on a handful of production motorcycles, all from Japanese Big Four manufacturers in the early 1980s. [1] [2] [3] Honda 1982 CX 500 Turbo / 1983 650 Turbo; Yamaha 1982-1983 XJ 650 Seca Turbo; Suzuki 1983 XN 85 Turbo; Kawasaki 1983-1985 GPZ750 Turbo; Honda CX650 Turbo had a 674 CC, 100 BHP V ...
The FIM initially banned their motorcycle from competing after their engines did not conform FIM rules [3] and the team was forced to run modified two-stroke, ten-year old Yamaha motorcycles until a compliant engine was ready at the 2003 Portuguese motorcycle Grand Prix, but the partnership lasted until 2005, when a technical partnership with ...
A "twingle" is a four-stroke twin-cylinder engine with an altered firing order designed to give power pulses similar to a single-cylinder four-stroke engine. Inline twins with a 360° crankpin offset or flat-twins can be easily converted into twingles by firing both of the cylinders at the same time and installing a camshaft or camshafts that ...
