The snafu occurs when a brake line in front is pinched between the fuel tank and the frame, causing the front brake fluid pressure to increase. Dealers will replace brake lines and install straps to keep them in place.
The company knows of five crashes and two minor injuries related to the defect, which it discovered last fall through warranty claims.
Harley-Davidson will notify owners later this month. Dealers will replace the brake lines for free and attach straps to hold them in place.
