A manufacturing error by brake manufacturer Nissin has claimed another motorcycle maker. Triumph is recalling the 2012-2013 Street Triple, Street Triple R, Daytona 675 and Daytona 675R because of the problem with the Nissin-supplied anti-lock brake modulator. The issue has already resulted in recalls for the 2014 Honda CTX700 and CTX700N, the 2013 Kawasaki Ninja 300 (and the Ninja 250 offered in Asian markets) and the 2013 Suzuki Hayabusa.
The problem stems from a misalignment in the tool Nissin uses to insert the brake fluid inlet check valves into the ABS modulator. The error may cause the valve to scrape against the body of the modulator, forming aluminum filings that may interfere with the outlet check valve, potentially causing a loss of ABS function, potentially leading to a crash. Documents filed with the Triumph recall say the misalignment was caused by insufficient sensitivity of the seat sensor of the body affixing jig.
According to those same documents released by the National Highway Traffic Safety Administration, it was Triumph that first identified the problem and alerted Nissin in December 2012. In the ensuing months, Nissin conducted an investigation and contacted other manufacturers that may be using the same ABS modulator in their models. On July 8, Nissin completed its investigation and advised manufacturers to issue recalls.
The documents also state Nissin remedied the jig which caused the issue on Jan. 23 and altered the sensitivity of the seat sensor on March 22.
Triumph manufacturers will replace the ABS modulators on the affected units.
The recall affects 384 units of the Street Triple, 626 units of the Street Triple R, 388 units of the Daytona 675 and 489 units of the Daytona 675R, all from the 2012 and 2013 model years.
