[UPDATE June 12, 2025: We heard back from Yamaha Motor Corporation USA about the Matrix headlights on Tracer 9s in the US. According to a Yamaha US representative, while the US model Tracer 9 does use the same light assembly as the Matrix-equipped models, the US version does not currently have the Matrix lighting upgrade found on its European counterparts.
The EU version has additional wiring, sensors, and a control unit that allow control of its various specialized LED functions, which the US version does not have at this time.]
