Yamaha G5 Regulation Specs

[Terry Beckingham]

Terry,

I can't find a Yamaha G5 in the action handbook which I have here (1991) 
but it appears that specs for all of the grands are the same.

Key height  62mm
Sharp height 12mm
Hammer blow 47.5mm
let-off 3-2mm
key dip 10mm
back check distance 16-15mm
drop  let-off +2mm

Hope this helps
