Premium quality German-engineered AE/Goetze piston rings are designed and built with anti-scuffing properties that promote smooth engine operation, reduced oil consumption, and long engine life.
This complete set of 71 mm piston rings is specified for the Triumph 650 twin-cylinder models and includes (4) compression rings and (2) oil control rings. Available in Standard size. A two-piece oil control ring with an expander spring ensures superior even radial pressure distribution across the circumference of the cylinder bore. Goetze piston rings are manufactured in Europe to the strictest quality standards.
The piston rings form a seal during compression and promote oil lubrication of the cylinder bore walls. They must be accurately sized to fit in the piston ring grooves with clearance. The current production Goetze piston rings are an excellent complement to the JCC pistons, marketed under the Emgo brand.
Ring end gaps must be checked and adjusted, if necessary, prior to fitment to the pistons. Care must taken when handling piston rings, as they are brittle and can be broken if mishandled, especially during fitment to the pistons. Suggested ring end gaps are .004″-.006″ per inch of bore for compression rings. End gap for the oil control rings is not as critical as the expander spring creates an even tension. The installation of the expander spring must be such that the gap of the spring is 180 degrees apart from the gap in the oil control ring.
