Product Information
The S3 Piston Kit is engineered for riders who demand precision and reliability from their 2-stroke engines. Constructed from a top-grade aluminum-silicium alloy, each piston is either cast or forged for durability and performance. The molybdenum disulfide protective layer ensures reduced friction and smoother movement within the cylinder, while nitrided steel rings improve sealing and wear resistance.
Designed to keep your engine responsive and reliable, this piston kit helps minimize vibration and allows your motor to rev faster and cleaner—ideal for off-road, enduro, or racing conditions.
