The heart of any motorcycle is its engine, and the Yamaha R15 V4 doesn't disappoint. This section will break down the engine specifications and performance aspects of the bike, so you can understand what makes it tick.

First off, the R15 V4 is powered by a 155cc, liquid-cooled, 4-stroke, SOHC, 4-valve engine. This might sound like a bunch of jargon, but let's break it down. The 155cc refers to the engine displacement, which essentially tells you how much fuel and air the engine can combust in each cycle. A liquid-cooled engine means that it uses a liquid coolant to regulate temperature, which helps in maintaining optimal performance even under stressful conditions. The 4-stroke configuration means that the engine completes its combustion cycle in four strokes: intake, compression, combustion, and exhaust. SOHC stands for Single Overhead Camshaft, which is a type of valve train configuration, and the 4-valve design means there are four valves per cylinder, allowing for better airflow and combustion efficiency. This combination results in a peppy and responsive engine that's perfect for both city commutes and spirited rides on the open road.

Now, let's talk power and torque. The Yamaha R15 V4 churns out a maximum power of around 18.4 PS (13.5 kW) at 10,000 rpm and a peak torque of 14.2 Nm at 7,500 rpm. These figures might not seem astronomical, but in the lightweight chassis of the R15 V4, they translate to an exhilarating riding experience. The high-revving nature of the engine means that it loves to be pushed, and you'll find yourself enjoying the smooth power delivery and quick acceleration. The Variable Valve Actuation (VVA) system is another key component here. VVA optimizes the valve timing based on the engine speed, providing a good balance of low-end torque and top-end power. This means you get strong acceleration from a standstill, as well as the ability to cruise comfortably at higher speeds.

The fuel injection system plays a crucial role in the engine's performance and efficiency. The R15 V4 uses a fuel injection system that ensures precise fuel delivery, resulting in better combustion, improved fuel efficiency, and reduced emissions.
