Wiseco 2264CS 2-Stroke Piston Ring Set for 57.50mm Cylinder Bore CS Type Single Ring

The Wiseco 2264CS is a CS-type replacement piston ring set designed for 2-stroke engines with a 57.50mm cylinder bore. This single-ring set is engineered exclusively for use with Wiseco forged pistons and is manufactured to the same exacting standards as the original ring supplied with the piston kit.

The CS-type ring set includes one chrome-faced, high-temperature alloy steel compression ring with an internally notched profile. The internal notch provides positive twist geometry, allowing the ring to tilt and seat precisely within the piston ring groove for optimal compression sealing. The ferrox-coated alloy steel construction delivers excellent durability and wear resistance across a wide range of cylinder bore compositions.

Key Features:

• CS-type: single chrome-faced, high-temperature alloy steel compression ring
• Internally notched design for positive twist and superior compression sealing
• Ferrox-coated alloy steel construction for enhanced durability
• Designed for 2-stroke engines with a 57.50mm cylinder bore
• Compatible with cast iron, Nikasil, and composite cylinder bore coatings
• Engineered and tested specifically for use with Wiseco forged pistons

Important: Only Wiseco replacement ring sets may be used on Wiseco pistons — ring styles cannot be interchanged. To confirm the correct ring type and bore size for your piston, refer to the markings stamped on the piston dome before ordering.
