OK, I bough this Yamaha cover for my Tyros 2 but it is too small. If you have a PSR series keyboard, it will fit. The part number is KDC-3800. Cover is brand new, I just took it out to see if it will fit the Tyros. It has a Yamaha name and logo on it. I paid $14.95 and will take that shipped within US. Or, if you have a Tyros cover and would like to swap, let me know.
