Triumph is recalling certain model year 2006-2009 Street Triple, Street Triple R, and Daytona 675 motorcycles. The regulator/rectifier can overheat and prevent the motorcycle from charging. Once the battery is fully discharged, the motorcycle may stall. If the motorcycle stalls, there is an increased risk of a crash leading to personal injury.
