Yamaha N1110021 Complete Neck Assembly for YAS23 Saxophone

The Yamaha N1110021 Complete Neck Assembly is a factory-original replacement part for the Yamaha YAS-23 alto saxophone, one of the most widely used student-level alto saxophones in music education. The neck—also called the crook or gooseneck—is a critical component that directly affects airflow, intonation, and tonal response across the instrument's range. When a YAS-23 neck sustains dents, develops corrosion, or has a worn tenon cork that no longer creates an airtight seal with the body, replacing it with this genuine assembly restores the saxophone to its intended playing condition.

As a complete assembly, this part is manufactured to Yamaha's original specifications for bore taper, wall thickness, and receiver dimensions, ensuring a precise fit on the YAS-23 body without the need for custom modifications or adapter work. This makes it a reliable choice for school music programs, private instructors, and individual players maintaining a YAS-23 that remains in otherwise good condition. While the physical installation involves sliding the neck into the body receiver and securing it, having the cork fit, mouthpiece alignment, and octave key linkage checked by a qualified repair technician will ensure the instrument performs at its best after the replacement.
