Thomann site does have a few mistakes in the details.
That Gator bag says at bottom 'suitable for Tyros5-61!
So, if Thomann bag description is correct, will be a tight fit. Personally, I'd rather have a bit extra, as the end corners are vulnerable if dropped!
I see Vali reviewed it on their site, too. He will come back and comment on the 'fit', I'm sure.
I bought the Yamaha SCC bag from Thomann .. they are currently asking me to review it!
This one has over 25mm firm padding around each end.
