Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When accelerating through 2nd gear the bike jolts as it apparently skipping a tooth on the gear. After researching on the forums as well as a working with Triumph dealer I was informed that this is a known issue and it has occurred on hundreds of these bikes. Triumph actually had an upgrade kit to repair this known issue but only if it happened while the bike was still under warranty. My bike was out of warranty by its age but still only had 8k miles. Triumph refused to repair the damage. …”
NHTSA complaint #10456182, filed 2012-04, 8,500 miles“Transmission dangerously jumping out of gear between 1s and 2nd, hits neutral spots under power. Additionally getting dangerous steering shake between 45-25 MPH decelerations. Bike has under 9,900'miles. Dealer found a transmission oil seal installed backwards by factory, upon tear down/diagnosis of transmission Triumph so far refuses any help, bike too old they say. Bike is a $6,300 total loss' due to repair cost exceeding $6,400+ for transmission alone.”
NHTSA complaint #11140802, filed 2018-10, 9,870 miles“2006 Triumph rocket 3, the transmission jumps out of second gear when accelerating. Triumph has a transmission upgrade that addresses this problem but will not fix it out of warranty. This problem can result in a crash if the transmission jumps out of gear when passing another vehicle or when moving from a stop with traffic behind the motorcycle.”
NHTSA complaint #10395623, filed 2011-04, 9,500 miles“First noticed after purchase in 2013 while shifting from first to second gear, the manual five speed transmission jumps out of second gear. This happens every time, under various load conditions and road hazards. Speaking with Triumph corporate service, they recognize the fault, have received thousands of complaints world wide, and offer on a case by case basis, a part upgrade as a repair. They do not however cover labor to effect the upgrade after the original warranty period. Not effecting a recall and putting thousands at risk. …”
NHTSA complaint #10619331, filed 2014-08, 21,839 miles“Transmission jumps out of gear while accelerating. This is a known issue but Triumph is content on letting them fail and then the consumer is stuck for the cost of repairs. The Triumph forums have shown that this has happened to thousands of owners. If the vehicle is still in warranty then they have an upgrade kit that they install. However they are playing the wait and see game so that those owners that have the issue after the warranty is up they can charge for the upgrade. This is a safety issue and the failures can happen at anytime. …”
