WASHINGTON, D.C. - Triumph is recalling some 2012-13 Street Triple and Street Triple R naked bikes manufactured in July 2012 as well as 2012-13 Daytona 675 and 675R bikes made between September 2012 and June 2013 for problems associated with the anti-lock brake system (ABS), according to NHTSA.
ABS-RELATED RECALLS are affecting several vehicle manufacturers. The common thread: each recalled motorcycle features the latest compact anti-lock brake system modulator from Nissin in Japan. The recalled bikes from Honda, Kawasaki, Suzuki and Triumph use the new ABS unit, claimed to be the smallest and lightest on the market.
A manufacturing defect during the assembly phase of the Nissin Hydraulic Control Unit can cause a loose chip of aluminum to remain inside the ABS unit. Normal braking function is unaffected; however, the loose metal chip may prevent the HCU check valve from operating properly -- which in turn could prevent normal ABS function during a skid. If a rider expects the ABS to function normally and instead locks one or both wheels, the risk of a crash increases.

Debris in the system may cause the ABS to lose functionality, increasing the risk of a crash. About 1,887 vehicles are affected in the recall, according to Triumph.
The defect is traced back to the ABS manufacturer, Nissin Kogyo Co. Ltd. of Japan, according to documents provided to NHTSA. Honda, Suzuki and Kawasaki have issued similar recalls (see below). Nissin reportedly remedied the issue in January, Triumph noted.
Aluminum filings generated during production reportedly remained inside the product. This could potentially grind the seal part of the outlet check valve when the ABS is operated, causing the functional capability of the seal to be lost along with the functional capability of the ABS, Triumph reported.
Dealers will be asked to replace the ABS modulator. Triumph had not yet provided a notification schedule at presstime.
