2016 Triumph Thruxton

The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE21017) on July 9, 2021 for model year (MY) 2016-2019 Triumph Thruxton and Speed Triple model motorcycles based on allegations of loss of front braking performance.Vehicle Owner Questionnaires (VOQ) indicated riders were experiencing a soft front brake lever that could result in an unexpected extended stopping distance. On July 28, 2021, ODI sent an Information Request letter to Triumph to learn more about the subject components and alleged defect.On September 24, 2021, Triumph submitted its response, which ODI analyzed.ODI learned that the majority of the VOQ incidents occurred two or more years after the motorcycle was manufactured. The manufacturer recommends changing the brake fluid every two years, regardless of mileage. As the manufacturer’s warranty lasts for two years from the date of sale, many dealers covered the complicated brake fluid replacement procedure under warranty. However, most of the motorcycles involved in these incidents were overdue to have their brake system serviced. Triumph conducted testing of the brake system to better quantify what riders were experiencing.Triumph found pulling the lever a second time immediately after an initial pull did result in less lever travel for the same force exerted on the lever.This reduction was two millimeters or less.Additional testing was conducted to ascertain the caliper force generated relative to various lever forces.Triumph found that the caliper force varied +/- 2% between the first and second pull of the front brake lever and any given applied force. Triumph claimed that the lack of proper maintenance was the cause of the soft brake lever.Triumph conducted additional testing to quantify this claim.The lever travel between the first and second pull increased 150% on an improperly maintained system versus a properly maintained system.However, the caliper force only decreased 2-3% on average with this increased lever travel, further indicating that the subject motorcycles are capable of fully stopping. ODI located and evaluated a subject motorcycle.Measurements were taken and confirmed there was a small decrease in lever travel between the first and second pull.ODI then conducted a series of hard braking events, which did not produce evidence that the difference in lever travel resulted in an extended stopping distance. ODI also considered Fatal Accident Reporting System (FARS) data.ODI identified six fatal events that involved a subject vehicle.The service history records were reviewed for each motorcycle, however,none of the records included any mention of braking problems and thus there is no indication that the alleged defect may have contributed to the fatal crashes. As of this time there are no VOQ or manufacturer claims reporting an injury, fatality, or crash arising from this issue.Based on the available information, including the absence of such events after nine years of service on the oldest motorcycles, ODI is closing this investigation.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency reserves the right to take further action if warranted by the circumstances.

the front brakes are inconsistent when engaged. the first squeeze of the brakes are spongy and almost completely squeeze down and then subsequent braking with completely clamp in 1”. The problem does not go away even after bleeding the brakes. This has occurred since ownership of over 1 year. I only came across other owners with the same issue after a google search and there is an forum thread on the issue.

The wire harness has torn under ignition. The traction control stops working, needles bounce, and at times will not start. The wire pulls when the handlebars are turned to the right. I brought it to Moto primo to have it fixed. There was a recall for this issue and they want to charge me over $700 for an issue that they are obviously aware of. I had the bike in AZ over last winter and brought it in on a different recall. Moto primo said that the dealer looked at the issue in Phoenix but did not replace the part. They told me that I have to deal with the dealer in Phoenix which is 1800 miles away. This is a very dangerous thing. The needles initially started bouncing when I was driving from Phoenix to Minneapolis. It was doing it again when I was in MN. I went to blogs and read that there were issues where the wires stretch and tear when the bars are turned to the right. I looked at the wiring and it was torn and stretches when the bars were turned.

Brakes feel spongy or grinding at times. The grip on the front brakes is not good.

The front brake requires a first 'pump' to become effective. On subsequent application the brakes work as expected. After a short time I need to 'pump' the brake again (when first applying the brakes I can almost pull the lever to the grip). This is a known problem on many owner forums. Due to the safety hazard this should really be addressed.

Very time I push the front breaks, it feel spongy. First push the leveler goes almost all way down. It becomes more firm once you push it two or three time more, however, it vanishes after that. I took it to the dealer but they said that the breaks are working good. I have also changed the break fluid and bled the system according to the maintenance schedule but it has not worked at all. I have read on Triumph groups that this has been existing problems on Thruxton and speed triple models between 2016-2020. However, Thriumph hasn’t published a recall for it. It has been a serious safety problem on my bike. Fortunately, I have not had a serious accident but I had some close calls. I am writing from Mexico City, Mexico. Thanks and regards

Front brake lever has an issue wherein it is soft and requires multiple pulls or deploys to full engage resulting in both inconsistent and unsafe operation. It has been ongoing and apparently widespread with other owners and not something repair shops have been able to localize or remedy.

I have had this motorcycle since new in 2016 and have put 20,000 miles on it. It has for most of its life had a problem with the brembo front brakes where they do not fully engage until you pump the brake lever twice. I had taken it to the dealer multiple times while under warranty and had the brake fluid replaced and bled multiple times. While inititially the new fluid helps, nothing seems to be a permanent fix and the problem returns. More recently I had the front brake calipers disassembled, cleaned, fluids changed and it is still just as bad as ever. I had to replace the stock brake lever with one that is adjustable to get more leverage so that the brake lever does not bottom out against the handlebar. When that happens you need to quickly pump the brakes to actually stop. It can be very scary. The service manager at my local Triumph dealer apologized that they were not able to make the brakes work properly. Also with very inconsistent brake response it can be challenging to properly judge stopping distances and required reaction times.

The front brake lever first pull has always been soft, since the motorcycle was new. The second pull is firm and as one would expect. I brought the motorcycle to the dealer where I purchased it and had them inspect the brakes and perform a bleed operation, which I had to pay for. The technician found nothing wrong and there was no change in the first brake pull. This issue remains to the present day.
