Wiseco dirt bike pistons are replacement engine pistons for motocross, off-road and trail motorcycles. They are available as individual pistons and as piston kits. The line is designed to restore compression and engine performance during a rebuild or top-end refresh.

Key Features:

• Forged aluminum construction for strength and durability under high-RPM, high-load operation
• Designed for 2-stroke and 4-stroke dirt bike engines, depending on the part number
• Available in standard and oversize bore options to suit worn or re-bored cylinders
• Precision-machined for accurate ring sealing and consistent piston-to-wall clearance

Wiseco has built pistons for powersports and racing engines for decades. Choose the part number that matches your engine and your cylinder bore size. Each variant in this line is listed on its own page with its specific details.
