Triumph 650 750 Aerco Big Bore Goetze Ring STD Size Set PN# TBS-0154

This is a complete replacement piston ring set for use with the Aerco 650 to 750 long-rod big bore kit pistons in standard condition.

Premium German-engineered Goetze piston ring set is of the finest quality available for the 76mm pistons in the big bore kit from Aerco and others.

The piston rings form a seal during compression and oil retention in the cylinder bores.

The piston rings are installed on the pistons so the gaps are staggered from one another to form a compression seal.
