The 998r engine id indeed a 999cc short stroke with ti rods the same as a 999r (03) engine. In Fact all the 999r (04) model has extra is some cosmetic changes, carbon cam belt covers, mag cam covers.

I think the biggest difference your talking about also relates to the situation emmett and Rutter were in last year with their choice of engines.
998cc v999cc whatever they were called.
