Electrical system: wiring
- What is wrong
- Yamaha Motor Corporation, USA (Yamaha) is recalling certain 2012-2013 Yamaha XTZ12 Super Tenere motorcycles. Over time, a gap may develop in the protective sealant where the lead wires of the accelerator position sensor (APS) and throttle position sensor (TPS) connect to the electronic control unit (ECU). This may cause corrosion on the wires, preventing the engine from returning to idle after the throttle is released.
- Risk
- If the engine does not return to idle when the throttle is released, it can lead to a loss of control, increasing the risk of a crash.
- Remedy
- Yamaha will notify owners, and dealers will bypass the wire lead connection with a new sub lead harness multi-connector, free of charge. The recall began October 26, 2018. Owners may contact Yamaha customer service at 1‑800‑962‑7926. Yamaha's number for this recall is 990122.

Exterior lighting: headlights

In the affected motorcycles, use of the headlight may generate enough heat to cause the bulb connections to expand, resulting in arcing in the headlight bulb socket which could cause the socket to overheat, melt and cause the headlight to malfunction.
- Risk
- A headlight failure reduces the rider's ability to see clearly and the motorcycle's visibility to oncoming traffic, increasing the risk of a crash.
- Remedy
- Yamaha will notify owners and dealers will replace the headlight socket, free of charge. The recall began on March 10, 2014. Owners may contact Yamaha at 1‑800‑962‑7926.
