Understanding Motorcycle Engines

Engine 101

At Rideworx, our passion is motorcycles, and we know that the heart of every motorbike is the engine. This intricate piece of machinery is a marvel of engineering, powering you down Woking's roads, and transforming your ride into a thrilling experience. However, understanding how it works might seem daunting for a beginner. That's why we've compiled this beginner's guide to motorcycle engines.

The first step in understanding your motorbike's engine is knowing its basic structure. It's comprised of several parts, but we'll focus on the crucial ones: the cylinders, pistons, spark plugs, and the crankshaft. The relationship between these components is where the magic happens, resulting in your motorcycle's raw power.

Power to Weight

The number of cylinders in a motorbike engine can vary. They can be single, twin (V-twin or parallel-twin), triple, or four-cylinder engines. The configuration impacts the motorcycle's performance, weight, and fuel economy. For instance, single-cylinder engines are usually lighter, offering a great power-to-weight ratio, ideal for off-road bikes and smaller city motorbikes.

Pistons and Spark Plugs

The piston's role in the engine is significant. Positioned inside the cylinder, it moves up and down, performing the intake, compression, combustion, and exhaust strokes. This four-stroke process is the life cycle of an engine.

Spark plugs ignite the fuel-air mixture that enters the cylinder during the intake stroke, pushing the piston down and turning the crankshaft. This rotational motion is then transferred through the transmission to your motorcycle's wheels


Next, you'll want to familiarise yourself with terms like "engine displacement" and "compression ratio". Engine displacement, often measured in cubic centimetres (cc) or litres, represents the cylinders' total volume. Bigger displacement usually equates to more power but also higher fuel consumption.

Compression ratio, on the other hand, refers to the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, compared to the volume when it's at the top. Higher compression ratios typically result in greater engine efficiency.
