Not sure if the article mentions it or not (I can't get the page to load at the moment), but I assume he's being offered the 3rd bike in the team. [Talmacsi is the 3rd rider in the Aspar team--even though he's leading the championship--and next year he'll be too old for the 125s.] That would definitely be a step up from his current Honda, but not so big a difference to a KTM, should Repsol switch to them in 2008.
I think he would stay with Repsol if the KTM switch were to happen, but if it doesn't then I guess it will come down to his loyalty to Puig.
