Everything below is an owner-reported complaint submitted to NHTSA about the 2020 Triumph Rocket Iii Roadster, grouped by the component NHTSA recorded on the report.

Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
2020 issues: Within 500 miles of ownership, front brake goes out, dealer bleeds, one week later same thing happens, then they warrantied a new brake master cylinder. Next in about 1000 miles the rear brake starts becoming soft (this is before the rear brake recall) Dealers bleeds... same issue again with the pedal becoming soft. I give up and ride the bike until winter. 2021 issues: Rear brake recall gets performed this year, as the rear brake had alot of air in it from sitting over the winter... how the [XXX] does a rear brake bleed (this is the recall fix) correct this issue after sitting for 6 months over winter... There must be a different problem. Air doesn't just magically appear in the brake system unless there's a issue, there was quite a few people saying the same thing after winter, the rear brake just went down to the floor with no pressure... about a month later the rear shaft drive starts making all sorts of noise... dealer replaces under warranty. This bike should be deemed unsafe with all the brake issues and shaft drive issue. If there's anyway this can be considered a lemon in the state of Ohio please contact me. I'm tired of getting the run around. Front brake has been solid since the fix. Rear brake is still [XXX] and the rear shaft was not fixed. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
