Common problems with the 2005 Rocket III
NHTSA's file holds 20 owner complaints on the 2005 Triumph Rocket III. Owners named the electrical system most often: 6 complaints, and half of the 6 that list a mileage came after 10,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Electrical System | 6 | 6 | 10,300 |
| Engine And Engine Cooling | 5 | 5 | 7,000 |
| Power Train | 5 | 5 | 15,500 |
| Engine | 1 | 1 | Under 5 mileages |
| Fuel System, Gasoline | 1 | 1 | Under 5 mileages |
Of the 20 complaints, none reports a crash, none reports a fire and 2 report an injury (2 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2005 Rocket III
The 20 mileages owners gave run from 1 to 30,300 miles. A quarter are at or under 605 miles, half at or under 8,500, three quarters at or under 21,000 and nine in ten at or under 30,000; none came after 100,000 miles, none after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2005 Rocket III wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: all 20 came at or under 100,000 miles, so they say nothing about how many miles a 2005 Rocket III can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 1 mile |
| 25th percentile | 605 miles |
| Median (50th percentile) | 8,500 miles |
| 75th percentile | 21,000 miles |
| 90th percentile | 30,000 miles |
| Highest mileage listed | 30,300 miles |
| Complaints after 100,000 miles | none |
| Complaints after 150,000 miles | none |
| Complaints after 200,000 miles | none |
Is the 2005 Rocket III a good year?
Complaint counts cannot say whether the 2005 is a good or a bad Rocket III: they rise with how many were sold and how long they have been on the road. They show how the 2005 compares with the other model years in NHTSA's file.
With 20 complaints, the 2005 drew the most of the 2 Triumph Rocket III model years from 2005 to 2006 with 10 or more complaints. The fewest: the 2006 (15).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2005 (this page) | 20 | 20 | 8,500 |
| 2006 Rocket III | 15 | 14 | 9,500 |
2005 Triumph Rocket III recalls

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2005 Rocket III lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2005 Rocket III.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- Every one of the 20 complaints on the 2005 Triumph Rocket III lists a usable mileage.
- NHTSA names counted: ROCKET III and ROCKET III CLASSIC. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: ROCKET III and ROCKET III CLASSIC.
