Yamaha YUS1 vs YUS3 vs YUS5 Comparison Chart
The YUS series is Yamaha's premium upright: CFX-grade hammer felt and strings, a tone escapement and hand voicing. Here is how the three models differ.



The YUS series sits above the U series in Yamaha’s upright line. Yamaha builds all three models with the hammer felt and strings of its CFX concert grand, a tone escapement that lets the sound out of the cabinet, and voicing by hand. This chart shows what changes from the YUS1 to the YUS5.
The Differences in Brief
- YUS1: the 47-3/4″ model, for rooms where a taller upright won’t fit.
- YUS3: the same design at 51-1/2″, with the larger cabinet’s bigger sound.
- YUS5: also 51-1/2″, with the keyboard action of Yamaha’s top grands, Ivorite key tops, and a true sostenuto as the middle pedal.
- All three: CFX-grade hammers and strings, tone escapement, double casters, soft-close fallboard, and Silent, TransAcoustic and Disklavier versions.

Head-to-Head Comparisons
Yamaha YUS1 vs YUS3
Both have the YUS series’ CFX-grade hammer felt and strings and its tone escapement. The difference is size: the YUS3 is 51-1/2″ tall to the YUS1’s 47-3/4″, and weighs 545 lb to the YUS1’s 504 lb. The taller cabinet gives it a fuller, longer-sounding bass.
Yamaha YUS3 vs YUS5
The same 51-1/2″ cabinet. The YUS5 adds the keyboard action of Yamaha’s top grand pianos, Ivorite white key tops and wood process composite black keys, and a sostenuto middle pedal in place of the YUS3’s muffler pedal. It weighs 558 lb to the YUS3’s 545 lb.
Yamaha YUS1 vs YUS5
The two ends of the series: the YUS5 is nearly 4 inches taller, with the grand-piano action, Ivorite key tops and a sostenuto pedal. The YUS1 gives you the YUS sound in the 48″ cabinet.
Which Is Right for You?
The YUS1 and YUS3 differ mainly in height, so the room usually decides: the YUS3 has the fuller bass if it fits. The YUS5 is for the player who wants an upright to feel as close to a grand as possible, with its grand-piano action and a sostenuto pedal for advanced repertoire.
