ON THE INVOLVED VEHICLES, ONE OR BOTH OF THE FRONT BRAKE CALIPER BOLTS MAY BREAK. THIS COULD ALLOW THE BROKEN PORTION OF THE BOLT TO DRIFT INTO THE ADJACENT ROTATING WHEEL SPOKES. SHOULD BOTH CALIPER BOLTS BREAK, THE INNER CALIPER HALF MAY BECOME DETACHED FROM THE MOTORCYCLE.
Remedy: DEALER WILL REPLACE BOLTS WITH IMPROVED TYPE BOLTS, WHERE NECESSARY.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
