CYLINDER KIT 40.00mm POLARIS 50 SCRAMBLER SPORTSMAN PREDATOR

The 40.00mm cylinder kit is compatible with Polaris 50cc two-stroke models, including the Scrambler 50, Sportsman 50, and Predator 50. These models utilize a 40mm bore, 10mm wrist pin, and 50mm stud spacing. However, Polaris 90cc models—such as the Scrambler 90, Sportsman 90, and Predator 90—require a larger 52mm bore cylinder kit. Therefore, this 40mm kit is not suitable for 90cc models.?
