An overall introduction to motorcycle displacement and how it affects motorcycle performance

What is motorcycle displacement

Motorcycle displacement refers to the gas volume inhaled or discharged by the motorcycle cylinder within a certain stroke. Choosing a suitable motorcycle displacement requires considering personal needs and budget. In the development process of motorcycles and motorcycle industry, motorcycle displacement is a very important parameter, which determines the power performance and economy of the motorcycles.

• The meaning motorcycle displacement cc:

The cc in motorcycle displacement is the unit for measuring motorcycle displacement and is also an important indicator of motorcycles. This volume is a volumetric quantity, usually expressed in units of cubic centimeters (cm³) or cubic inches (in³). For the Chinese motorcycle market, cubic centimeters are generally used as the unit of displacement.

• How to calculate motorcycle displacement cc:

The calculation method of motorcycle displacement cc is usually based on the diameter and stroke of the cylinder. The specific calculation formula is as follows:

Displacement cc = π × (cylinder diameter/2)² × stroke

The cylinder diameter is usually in millimeters (mm), and the stroke is in millimeters (mm) or inches (in). According to this formula, we can calculate the motorcycle displacement.

Relationship between motorcycle displacement and performance

• Power performance: The larger the displacement of a motorcycle, the stronger its power performance usually means. Because large-displacement motorcycles can take in more air and produce greater power output. Generally speaking, large-displacement motorcycles have higher top speeds, faster acceleration, and better hill-climbing performance.
• Economy: The larger the motorcycle displacement, the greater its fuel consumption. Because large-displacement motorcycles require more fuel to generate power, their fuel consumption is relatively high. When driving in the city, larger displacement motorcycles may require more frequent refueling.
• Handling performance: The larger the motorcycle displacement, the better its handling performance usually is. Because large-displacement motorcycles usually have larger frames and heavier bodies, no mention the other motorcycle parts, this makes them more stable at high speeds. In addition, larger-displacement motorcycles usually have better suspension and braking systems, which makes them better in terms of handling performance.
• Price: The larger the motorcycle displacement, the higher its price usually means. Because large-displacement motorcycles usually require higher manufacturing costs and technical content, their prices are relatively high. Additionally, larger-displacement motorcycles typically have higher maintenance costs and insurance premiums.

To sum up, the displacement cc of a motorcycle is one of the important indicators to measure its performance. Choosing a motorcycle with a suitable displacement requires considering personal needs and budget.

If users need a motorcycle with excellent power performance and handling performance, a large-displacement model may be more suitable for them; but if they need an economical and fuel-efficient motorcycle, a small-displacement model may be more suitable for them. When purchasing a motorcycle, it is recommended to carefully compare the performance, price and maintenance costs of different models in order to choose the model that best suits users.

Classification of motorcycles base on displacement

According to the motorcycle displacement size, motorcycles can be divided into three categories: small displacement, medium displacement and large displacement. The specific categories are as follows:

• Small-displacement motorcycles: Usually with a motorcycle displacement of less than 100cc, suitable for short-distance travel and urban travel. This kind of motorcycle usually has a lighter body and lower manufacturing cost, and the price is relatively low, making it the first choice for entry-level motorcycle enthusiasts.
• Mid-displacement motorcycles: Usually the motorcycle displacement is between 100cc-250cc, suitable for short and medium-distance travel and urban commuting. This kind of motorcycle has moderate power and performance and can meet the needs of ordinary consumers. The manufacturing cost and price are more affordable than higher-displacement motorcycles.
• Large-displacement motorcycles: Usually with a motorcycle displacement of more than 250cc, suitable for long-distance travel and competitions. This kind of motorcycles usually have stronger power performance, excellent handling performance and luxurious configuration. The price is relatively high, and it is the first choice for professional motorcycle enthusiasts and competitive athletes.

Small-displacement models generally have the characteristics of compact body, light weight, easy control, fuel-saving, and low maintenance costs. The disadvantage is that the power is relatively weak and the experience of passionate driving is lacking. Moreover, most small-displacement models have relatively low configurations.

If the daily commute is within 20km one way, the power of small-displacement models is sufficient, and their heat level is relatively low, which makes them very suitable for novice users with limited budget to practice. Among them, Wuyang Honda CB190R and Suzuki’s GIXXER155 are good choices. We have previously introduced some well-known small-displacement motorcycles.

In recent years, global motorcycles have developed rapidly, like the Indonesia motorcycle market and motorcycle in Europe, and middle-displacement models have emerged one after another. The reason why models of middle motorcycle displacement are so popular is that they take into account the advantages of small-displacement models and large-displacement models.

Although the price is slightly more expensive, the power improvement it brings is a lot. The most important thing is that the control difficulty does not increase too much. Generally, users who are familiar with small-displacement models can also flexibly use mid-displacement models.

If users need to run on high speeds and their daily commute does not exceed 40km, mid-displacement models can fully meet the need. Moreover, most of these models are usually twin-cylinder, which is better than the single-cylinder of small-displacement models in terms of vibration suppression, and can provide a more comfortable driving experience. There are many recommended models in the mid-displacement field, such as Honda CB400 F/X, KoveMoto 321 series, Kawasaki Z400, Wuji 350AC, Zontes 350D, etc.

It is not recommended for novice riders to buy large-displacement models over 400cc at the first place. Models over 400cc motorcycle displacement have more power and heavier curb weight, and have higher requirements for center of gravity control and throttle operation. And it is easy to cause accidents if the riders are not careful. If a novice wants to drive a large-displacement vehicle,  as a motorcycle safety tips, it is recommended to find a formal safe driving training institution to practice and strengthen the driving skills first.
