YAMAHA issued a recall on multiple vehicle models

On certain motorcycles, an improperly designed Throttle Position Sensor (TPS) could cause an intermittently unstable idle when the motorcycle is stopped or during low-speed operation. If the engine stalls after the operator disengages the clutch in a low gear while riding, the rear tire might slip momentarily if the operator abruptly re-engages the clutch. This could result in a crash with injury or death. Correction: Dealers will replace the TPS.
