4-Stroke Pistons
Why Choose Wiseco 4-Stroke Pistons?
A 4-stroke engine is an internal combustion engine that completes four strokes—intake, compression, power, and exhaust—during two crankshaft rotations. This design ensures efficient fuel combustion and better control over exhaust emissions, making it the standard in high-performance and Powersports applications.

Frequently Asked Questions: 4-Stroke Pistons
If you’d like to learn more about Wiseco 4-stroke pistons, check out the answers to our most frequently asked questions below.
What’s the Difference Between 2-Stroke and 4-Stroke Pistons?
2-stroke pistons operate in engines that complete a power cycle in two strokes of the piston (one crankshaft rotation), making them simpler and more lightweight but often less durable. 4-stroke pistons, on the other hand, work in engines that complete a power cycle in four strokes (two crankshaft rotations), resulting in more efficient combustion and better emissions control.
How Does a 4-Stroke Engine Work?
A 4-stroke engine operates through four stages: intake, compression, power, and exhaust. During the intake stroke, the piston moves down, drawing in a fuel-air mixture. In the compression stroke, the piston moves up, compressing this mixture. The power stroke occurs when the spark plug ignites, forcing the piston down and generating power. Finally, the piston moves again in the exhaust stroke, expelling exhaust gases. This cycle repeats to produce continuous power.
How Do I Choose the Right Wiseco Piston for My 4-Stroke Engine?
Choosing the right 4-stroke piston involves considering factors such as engine type, bore size, compression ratio, and specific application (e.g., racing, off-road, street). Wiseco provides a variety of options tailored for different engines and uses.
