What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Tl contact owned a 2004 harley davidson sportster. While driving approximately 65 mph, the contact applied the brake to slow down, but the brakes locked and never unlocked. The vehicle slid to a stop on its side and the contact sustained injuries. The motorcycle was severely damaged. There was no police report.
The reason the motor locked up was because screws from the air filter vibrated lose and were sucked into the motor causing the motor to lock up. Harley davidson has a known problem with vibrations, so putting screws in a place that can be sucked into the motor is a flaw, and this problem needs to be resolved before…
