This link shows (as some others do) that the max Style file size for Tyros1 is 120Kb.

Unfortunately Yamaha don't seem to have given similar info in their specs. for Ty2. The style features are the same though (Number of intros, fills etc.etc.) so it "may" (fingers crossed) be logical to assume Ty2 can cope with at least 120Kb. Whether it'll load more than that presumably depends on whether Yamaha increased the amount of buffer memory allocated to styles in Ty2 compared with Tyros.
