Jake Zemke will now no longer be replacing Roberto Rolfo on the Hannspree Honda Althea CBR1000RR machine at this weekend's Italian Round of the Superbike World Championship.

The American was due to replace the injured Italian but he was unable to get the required authorization through from the AMA federation in time for this weekend's fifth round of the series.

HANNspree Honda Althea SBK riders for Monza will be Giovanni Bussei.

Yesterday afternoon after a medical consultation he received the authorization to race from his medical staff and so he’ll ride the team’s Honda CBR 1000 RR.
