Limited data — recalls on file
NHTSA has just 22 complaints on file for the 2005 Triumph Rocket III — too few to judge reliability from owner reports alone — but 2 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
ON CERTAIN MOTORCYCLES, WHEN THE ENGINE IS RETURNING TO IDLE IT MAY STALL.
Consequence
IF THE MOTORCYCLE STALLS, THE RIDER WILL HAVE TO RESTART THE ENGINE INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL INSPECT AND DOWNLOAD NEW ENGINE MANAGEMENT SOFTWARE FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 17, 2007. OWNERS MAY CONTACT TRIUMPH AT 678-854-2010.
Defect
ON CERTAIN MOTORCYCLES, DAMAGE TO THE OIL SEAL OCCURRED DURING FINAL ASSEMBLY. ONCE DAMAGED SOME OF THE OIL IN THE DRIVE UNIT COULD ESCAPE PAST THE SEAL.
Consequence
IF UNDETECTED THE FINAL DRIVE UNIT COULD RUN LOW OF OIL AND SEIZE CAUSING THE REAR WHEEL TO LOCKUP, WHICH COULD RESULT IN A CRASH.
Remedy
DEALERS WILL REPLACE THE FINAL DRIVE UNIT. THE RECALL BEGAN ON JANUARY 25, 2005. OWNERS MAY CONTACT TRIUMPH AT 678-854-2010.

“UNDER ACCELERATION, ENGINE HAS A RATTLE LIKE A SPRAY PAINT CAN. I'VE DONE SOME RESEARCH, AND THIS IS A COMMON PROBLEM LEADING TO ENGINE FAILURE, DUE TO A TIMING CHAIN/SPROCKET ISSUE. I WOULD LIKE TRIUMPH TO ISSUE A RECALL TO FIX THIS, BEFORE IT FAILS. *TR”
“DT*: THE CONTACT STATED THE MOTORCYCLE INTERMITTENTLY STALLED WHILE DRIVING 20-25 MPH AND WHILE STOPPED AT STOP SIGNS AND LIGHTS. THE MOTORCYCLE ALWAYS RESTARTED AFTER THE THROTTLE WAS TWISTED FOR ONE MINUTE. THE DEALERSHIP WAS UNABLE TO DETERMINE THE CAUSE OF THE STALLING, BUT RESET THE COMPUTER…”
“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. *TR”
“DT: RIDING AT 5 TO 10 MPH COMING TO STOP, CONSUMER'S FRONT BRAKES LOCKED UP, AND A LOUD METAL PING SOUND OCCURRED. THE CONSUMER WENT TO THE DEALER FOR THIS PROBLEM, AND THE DEALER STATED THAT THE BRAKES WERE NOT PROPERLY INSTALLED AND THAT HAPPENED AT THE FACTORY. THE CONSUMER HAD HEARD LOUD…”
“TL* THE CONTACT OWNS A 2005 TRIUMPH ROCKET III MOTORCYCLE. THE CONTACT STATED THAT WHILE DRIVING 55 MPH, THE ENGINE WOULD REV VERY HIGH AND CAUSE PROBLEMS WHILE SHIFTING. THE VEHICLE WAS REPAIRED IN 2007 UNDER NHTSA CAMPAIGN ID NUMBER 07V455000 (FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM);…”
The record is thin — 22 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
According to NHTSA complaint data, the leading problem areas are electrical system (6 complaints), engine (6 complaints), transmission (5 complaints).
