The defect

The involved motorcycles were manufactured with front brake master cylinders in which the plunger piston bore diameter was honed .015 inches over maximum specifications. This oversized bore results in a poor fit between the elastomeric piston cup and the cylinder bore, which allows fluid leakage from the hydraulic system.

The remedy

Dealer will inspect and, if necessary, replace the front brake master cylinder assembly at no cost to owner.
