Std Bore Piston Rings for Polaris Indy XCR 700

Standard bore piston rings made for the 1998 Polaris Indy XCR 700, intended to replace worn rings and bring compression back to factory specification.

Overview

This standard bore piston ring set is made to fit the 1998 Polaris Indy XCR 700 and renew the seal between piston and cylinder wall. Worn rings cause hard starting, lost power, and oil burn, and a fresh set is the standard fix during a top-end job. Sized to the factory standard bore, they install without cylinder boring and suit riders rebuilding a 700 twin for the trail.

Specs At A Glance

Good To Know

Q: Are these rings oversized? A: No, they are standard bore rings made for the original cylinder diameter, so no machining to an oversize is required. Inspect cylinder taper and finish before fitting them.

Q: Can I install these without removing the engine? A: They go in as part of a normal top-end job with the cylinders pulled, so the engine should come out or the sled be stripped far enough to access the top end. Check ring end gap during assembly.

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