Tsubaki Parts & Accessories

Tsubaki are Japanese chain royalty — built the first sealed O-ring chain in the late 1970s and have been refining the technology ever since, currently up to the TX4-ring series. Every chain is pre-stressed, pre-stretched, and quad-staked at the pin heads to handle real torque without elongating early or pushing pins out under load.

Mostly relevant for chain-driven Sportsters and chain-conversion builds rather than belt-drive Big Twins. Range covers everything from Gamma roller chains for daily use up to the gold-finished X-ring sets for higher-mileage Touring applications.
