Hi Deane, congratulations on taking delivery of your Tyros 5-61 today.
Looks like a 'red letter' day for both of us as I received mine today too.

Though T5-61's only a mere pound lighter than Tyros 4 I sensed right away T5 feeling lighter than T4 when I picked it up.

Tyros 4 - 61 note: 14.5 kg (31.97 lbs)
Tyros 5 - 61 note: 14.0 kg (30.86 lbs)

Weight Differemce: 0.5 kg ( 1.11 lbs)
