Motorcycle according to the exhaust volume is divided into: booster (50cc or less), small-displacement motorcycle (50cc-250cc), middle-weight (400cc-750cc), large-displacement (600cc or more) 600cc or more are known as large-displacement.

Displacement motorcycle engine output will be greater, the car is more powerful, speed will be relatively faster, but the family motorcycle inside the 100-125cc between a few 150cc, the displacement size is actually only related to the speed performance and torque output size, the speed is actually almost the same.

Motorcycle Exhaust

1, how to calculate the exhaust: Bore: the diameter of the cylinder referred to as the cylinder diameter, the stroke: the piston in the cylinder to do the reciprocating motion, when the piston from the upper stop ( TDC), running to the lower stop. TDC), running to the lower stop (BDC), the distance traveled is called the piston stroke, referred to as stroke or stroke.

2, now take the 03 HondaCBR600RR as an example, the engine form, water-cooled four-stroke parallel four-cylinder 16-valve DOHC engine as an example, the cylinder bore (67.0mm) and stroke (42.5mm).

3, exhaust volume calculation method: the cylinder section area X stroke X number of cylinders = total exhaust cc, stroke: 42.5mm = 4.25cm bore: 67.0mm = 6.7cm, section area: 3.35 X 3.35 X 3.1416 = 5.25, section area 35.25 X stroke 4.25 X number of cylinders 4 = total exhaust 599cc.

Baidu.com, the four-stroke parallel four-cylinder 16-valve DOHC engine, for example, the bore (67.0mm) and (67.0mm) and the cylinder (42.5mm). /p>
