Having an inline engine (also known as an inline-four or straight-four engine) on a motorcycle offers several advantages:
Smooth power delivery: Inline engines are known for their smooth power delivery throughout the rev range. The design of an inline-four engine provides balanced firing intervals, resulting in consistent power delivery and minimal vibration. This smoothness enhances overall ride quality and control.
High RPM capability: Inline-four engines tend to have a higher rev limit compared to engines with fewer cylinders. This high-revving nature allows riders to access higher power outputs at higher engine speeds, making them suitable for sport-oriented motorcycles that require quick acceleration and high top speeds.
Compact design: Inline-four engines have a relatively compact design, particularly in terms of their width. This slim profile allows motorcycle manufacturers to create narrower chassis, contributing to better handling and agility. The compactness also helps to centralize mass, improving overall balance and maneuverability.
Power-to-weight ratio: Inline-four engines often have a favorable power-to-weight ratio due to their relatively light weight and high power output. This combination of power and weight can result in impressive acceleration and performance.
Versatility: Inline-four engines are versatile and can be used in various motorcycle types, including sport bikes, naked bikes, touring bikes, and even some adventure motorcycles. Their power characteristics and smoothness make them suitable for a wide range of riding styles and preferences.
Aftermarket support: Inline-four engines have been widely used in motorcycles for many years, which has resulted in a robust aftermarket support ecosystem. Riders can find a wide range of performance upgrades, parts, and accessories designed specifically for inline-four engines, allowing for customization and fine-tuning of their motorcycles.
It's important to note that these advantages are general characteristics associated with inline-four engines, but the specific performance and capabilities of a motorcycle depend on various other factors, including engine tuning, transmission, weight distribution, and overall bike design.
