This edition dresses the SP2 in the colours of the Castrol Honda World Superbike team, with which Colin Edwards won the 2000 and 2002 titles. The figures listed for it match the standard SP2, so it is essentially a livery variant of the updated RC51 with its stiffer frame and revised fuel injection.
