In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
The bike surges when shifting gears, due to fuel pump not operating properly. It will start a lower speeds, then begin to happen at higher speeds. 2 fuel pumps have been put into the bike and the issue still happens.
-
My son driving this motorcycle was cut off by another driver. The rear brakes appeared to have locked up. This resulted in a fatality- my son was killed. We just got notice that there is a recall for this brake issue and there is no repair available.
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
