Aprilia is either confident or cocky, because according to MCN, the Italian manufacturer’s racing department has halted development on the 2010 World Superbike spec RSV4 Factory race bike. Comfortable with Max Biaggi’s 58 point lead over Leon Haslam and his Alstare Suzuki, Aprilia wants Biaggi to focus on racing with his current setup, rather than risk having a prototype part breaking, and costing the team and Biaggi the World Superbike Championship.
