Triumph Motorcycles America, LTD recalls a small number of their 2016 Street Twin motorcycles that may pose a fire hazard due to a defective part. Model year 2016 Street Twin bikes manufactured from September 7, 2015 to November 21, 2015 are expected to pay a visit to the nearest dealership and undergo an inspection of the wiring harness under the fuel tank.
The problem was detected in the wiring sub-harness that splits from the main harness and supplies electrical power to the pump located inside the fuel tank.
A part of this harness passes through the fuel pump mounting plate, but it looks like the protective cover was manufactured defectively. As part of the routine testing procedures, Triumph disassembled one of the Street Twin motorcycles and inspected these components.
The investigation determined that excess molding flash resulting from an improper tool setting may damage the wiring insulation. As a result, the wiring may come in contact with the fuel. If this occurs, fuel might travel down the exposed wiring towards the sub-harness and even drip. In case of a short circuit or in high-temperature conditions, the fuel could ignite, resulting in a vehicle fire.
In January 2016, a Triumph quality engineer contacted the supplier of the sub-harness and was able to confirm "that tooling used to manufacture this component had been changed in September 2015. One of the changes had been to relocate the split line from a position intersecting with the electrical wiring to a position that avoided this intersection. The supplier also provided ship dates of the parts with the original design and parts with the revised design," NHTSA papers inform us.
Together with the supplier of the respective sub-harness, Triumph was able to track the exact defective batches and identify the bikes that have to be recalled. The dealers have been instructed how to identify defective units and to repair them before any further Street Twin motorcycle sale would be carried out.
The dealers will also inspect the recalled machines and replace the defective part with a new one that was manufactured correctly. The recall is expected to start this month (April 2016), and the NHTSA reports that no incidents (fires or injuries) have been filed so far.
