Does bike CC matters most???

While discussing about the bike, the first thing comes to our mind is how many CC the bike is?.  We filtering the CC, then see the brand, style, Cost, etc...

Is CC really matters???

First, here is a basic explanation of what cc’s means. CC’s refer to the engine displacement or capacity. In other words, how much space is inside the cylinders. On motorcycles this is usually measured in cubic centimeters (cc’s) or sometimes cubic inches (ci’s). On cars it is often measures in litres (1000cc = 1 litre).

Engine Displacement / Capacity (cc)

The formula is: Displacement = Pi X radius² X height = P X (½ X bore)² X stroke

As an example, let’s use The bore’s 57.3 mm and stroke’s 57.8 mm. However, since we seek the result in cubic centimetres (cc), we have to first convert milimetres to centimetres. Hence, the bore and stroke are 6.19 cm and 7.40 cm, respectively. Let’s plug in the numbers.

Pi X (½ X 5.73)² X 5.78 = 3.14 X (2.87)² X 5.78 = 3.14 X 8.21 X 5.78 = 149.04 cc

Lets seethe type of Motorbikes

Most common motorcycles have 1 cylinder in India and 2 cylinders having is slightly costlier, although some have 3, 5 or even 6. Usually people talk about the cylinders in conjunction with the position of the cylinders, for example a “V Twin” or “Inline Four.”

 Most modern motorcycles are “four strokes,” meaning the engine goes through four steps to produce power. 1) Sucks in air and fuel, 2) Applies pressure and ignites, 3) The mixture combustion, 4) exhaust is pushed out. This process is referred to as internal combustion.

4 Stroke Engine (Modern Bikes)

In 2 stroke Engine, four stages will take place in 2 stroke itself. Since the two stroke engine fires on every revolution of the crankshaft, a two stroke engine is usually more powerful than a four stroke engine of equivalent size. This, coupled with their lighter, simpler construction, makes the two stroke engine popular in chainsaws, line trimmers, outboard motors, snowmobiles, jet-skis, light motorcycles, and model airplanes.

Unfortunately, most two stroke engines are inefficient and are terrible polluters due to the amount of unspent fuel that escapes through the exhaust port.

Latest Emission norm (Both BS4 & BS6) does not allows 2 stroke bikes that's why these bikes are not now in sales

2 Stroke Engine (Eg Yamaha RX 100 )

Both types of engine have inherent advantages and disadvantages

Let’s look at some examples...

 In the 150cc class you have your two standard beginner recommendations. The Pulsar 150 and the Yamaha FZ. Despite the 150cc next to their names the bikes have nothing in common. The 150cc Pulsar puts out 13.8 horsepower compared to the last generation of the Yamaha which put out 12.2 horsepower

Typical Comparison

If you see both bikes have same CC, but different Torque and Horsepower

Torque - It is the pulling power of an engine. More the torque, easier it is for the engine to pull load - so it feels relaxed. Also, lesser need to change gears.

Power - It is the speed which an engine can rev up to. If an engine can pull up to greater rev, the engine is powerful. This is because this engine has a wider torque band. So, a powerful engine has greater torque at higher revs. So what happens? Each gear can pull further. Hence greater speed and acceleration.

More power means more fun... Have fun but drive carefully...

This will be applicable for all cars and other commercial vehicles too..

An analogy - In case of electricity -

torque = voltage
rpm = current
power = well power (watt)

So, finally Power 💪💪 is what that matters….
