The Yamaha R3 is a popular entry-level supersport motorcycle that has been thrilling riders since its introduction in 2015. With its aggressive styling, responsive handling, and punchy engine, it’s no wonder this bike has become a favorite among motorcycle enthusiasts. But one question that often pops up among riders, especially those new to the world of motorcycling, is: what CC is the Yamaha R3?
In this article, we’ll dive into the details of the Yamaha R3’s engine, exploring its displacement, horsepower, and torque output. We’ll also discuss how these specs impact the bike’s performance and what makes it an ideal choice for new riders.
Understanding CC and Engine Displacement
Before we delve into the specifics of the Yamaha R3, it’s essential to understand what CC means in the context of motorcycles. CC, short for cubic centimeter, refers to the engine displacement or the volume of the engine’s cylinders. In simpler terms, it’s the total volume of air/fuel mixture that the engine can combust in a single cycle.
Engine displacement is typically measured in CC or liters (L). The higher the CC rating, the larger the engine displacement, and consequently, the more power the engine produces. However, a larger engine doesn’t always translate to better performance. Other factors like compression ratio, bore and stroke, and engine architecture also play a significant role in determining an engine’s overall performance.
The Yamaha R3’s Engine Specifications
Now, let’s get to the heart of the matter – the Yamaha R3’s engine specifications. The R3 is powered by a 321cc, DOHC, inline twin-cylinder engine. This engine features a bore and stroke of 68.0 mm x 44.1 mm, respectively, with a compression ratio of 11.2:1.
The key takeaway here is that the Yamaha R3 has an engine displacement of 321cc. This relatively small engine size is intentional, as it allows new riders to gain experience and build confidence without feeling overwhelmed by excessive power.
Power and Torque Output
The Yamaha R3’s 321cc engine produces a maximum power output of 42 horsepower (30.4 kW) at 10,750 rpm and a peak torque of 21.8 lb-ft (29.6 Nm) at 9,000 rpm. While these numbers might seem modest compared to larger displacement engines, they’re perfectly suited for the R3’s intended use as an entry-level supersport bike.
The R3’s power delivery is smooth and linear, with a focus on low-to-midrange torque. This makes it ideal for urban riding, where acceleration and agility are more important than outright top speed.
Comparison to Other 300cc Class Bikes
To put the Yamaha R3’s engine specifications into perspective, let’s compare them to its competitors in the 300cc class:
| Bike | Engine Displacement | Power Output | Torque Output |
| — | — | — | — |
| Yamaha R3 | 321cc | 42 horsepower | 21.8 lb-ft |
| Kawasaki Ninja 300 | 296cc | 39 horsepower | 19.9 lb-ft |
| Honda CBR300R | 286cc | 30.7 horsepower | 19.9 lb-ft |
As you can see, the Yamaha R3 sits comfortably in the middle of the pack in terms of engine displacement and power output. However, its torque output is slightly higher than its competitors, which translates to better acceleration and responsiveness in real-world riding.

What does CC stand for in motorcycles?
CC stands for Cubic Centimeters, which is a unit of measurement for the displacement volume of an engine. In the context of motorcycles, it refers to the size of the engine, with a higher CC rating indicating a larger engine. A larger engine typically means more power and speed, but it can also impact fuel efficiency and handling.
In the case of the Yamaha R3, the CC rating is an important specification that determines its performance and classification. The Yamaha R3 has a 321cc engine, which is considered a mid-size motorcycle engine. This size engine provides a good balance between power and fuel efficiency, making the R3 a popular choice for both beginners and experienced riders.
What is the significance of CC in motorcycles?
The significance of CC in motorcycles lies in its impact on the bike’s performance, fuel efficiency, and handling. A higher CC rating generally means more power and speed, but it can also result in higher fuel consumption and decreased handling. On the other hand, a lower CC rating may provide better fuel efficiency but may lack power and speed.
In addition to performance, CC also affects the bike’s classification and licensing requirements. In many countries, motorcycles are categorized based on their engine size, with larger engines requiring more advanced licenses and endorsements. The Yamaha R3, with its 321cc engine, falls into a specific category that requires a certain level of licensing and riding experience.
How does the CC of the Yamaha R3 compare to other motorcycles?
The Yamaha R3 has a 321cc engine, which is considered a mid-size motorcycle engine. This is smaller than most full-size motorcycles, which typically have engines ranging from 600cc to 1200cc or more. However, the R3’s engine is larger than many smaller motorcycles, such as scooters and beginner bikes, which often have engines around 50cc to 250cc.
The R3’s engine size puts it in a sweet spot between power and fuel efficiency, making it a popular choice for both beginners and experienced riders. It’s also worth noting that the R3 is a supersport motorcycle, which means it’s designed for agility and handling rather than pure power. The 321cc engine provides the perfect balance for this type of riding.
