Good To Know

Q: Does this kit fit both the JS550 and 550 SX? A: Yes, the kit is listed for both Kawasaki JS550 and 550 SX models running the standard 75.00 mm bore. Always confirm your cylinder bore before ordering.

Q: Is machine work required to install this piston? A: This is a standard-bore piston, so it is intended for cylinders that measure within spec for 75.00 mm. If your cylinder is worn or scored, it may need boring to the next oversize instead.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
