Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I own a 2005 Triumph rocket motorcycle that produced excessive engine noise because of worn key ways in the cam chain. I was told when I first purchased the bike that these noises are normal. Having researched web sites concerning this issue I have found that his is prevalent in 2005 rocket 3 models due to the above listed problem. Triumph has fixed my problem by replacing all the cam chain components via warranty, but many other consumers are suffering from the same issue and their warranty has expired.”
NHTSA complaint #10205522, filed 2007-10, 200 miles“Bike jumps out of 2nd gear or wont go into 3rd, almost got runover. The sounds from the engine appear to be like a paint can rattle. There was a recall for the rear drive locking down and the idle stalling in traffic.”
NHTSA complaint #10241754, filed 2008-09, 21,000 miles“The contact owns a 2005 Triumph Rocket Iii. The contact stated that the output shaft bearing was installed backwards. This causes the bearing not to receive oil, the output shaft to stop turning, locks the rear tire, and the upper shaft creates a hole in the engine. Furthermore, the failure causes the engine to lose oil and the rear tire to become slippery. The manufacturer is aware of the failure and are repairing the vehicles that were sold overseas, not the ones sold in the united states. …”
