Bonamici Chain Adjuster Set
Complete fitment list at bottom of this page.
Italian made billet aluminum chain adjuster set that allow you to more precisely, and more confidently adjust your chain.
Sold as a LH and RH pair, with installation instructions.
*Please note, though they look substainally similar, these chain adjusters do not fit on the '21 V4 swingarm. The '21 swingarm is wider at the rear so the retainer tab does not catch as designed. This photo shows how the retainer tab does not reach the back of the swingarm.
