100 mm Piston Ring Set by VERTEX — a set of rings designed to restore cylinder sealing and engine compression on quads and roadsters equipped with a 100 mm piston diameter. An essential spare part for any top-end operation, this set helps minimize compression loss and control oil consumption when installed according to manufacturer specifications.
Compatible with several off-road and utility models (examples: YAMAHA YFM 700 GRIZZLY EPS CAMO 4WD 2008, YAMAHA YFM 700 GRIZZLY EPS 4WD 2008, YAMAHA YXR 660 RHINO SPECIAL EDITION 4WD 2007) — always check the diameter and reference before ordering. This ring set replaces worn parts during a re-bore or cylinder refurbishment.
Practical tips: install the rings carefully, respect the recommended axial and circular clearance, lightly lubricate the piston and rings during installation, and perform a gradual break-in after reassembly. For any significant work on the top end, prioritize a thorough check of the cylinder, piston, and bearing to ensure reliable restart.
