Triumph Motorcycles is recalling certain model year 2012-2013 Street Triple and Street Triple R motorcycles manufactured in July 2012; and model year 2012-2013 Daytona 675 and Daytona 675 R motorcycles manufactured September 2012 through June 2013. Due to a manufacturing error, the Anti-Lock Brake System (ABS) may malfunction and lose anti-lock functionality. The anti-lock function may not perform properly allowing for wheel lock up and skidding, increasing the risk of a crash. Triumph will notify owners and dealers will replace the ABS modulator, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Triumph at 1-888-283-5288. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
