Big Base

The ‘Big Base’ Indian 648s were the ultimate development of flathead engine technology, with high-dome pistons carrying two compression rings and one oil ring. The name came from the huge oil capacities, because the bikes were fitted with extra-large sumps designed to help engines cope with the stresses of racing.

Its thought that only seven factory Daytona Sport Scout 648's are stll in existence, so the chances of ever owning one are highly unlikely.

With a lot of Indian tuners still chasing ultimate performance for their vintage racing Scouts, it is possible to build a replica motor, up until now the sticking point has been availability of cylinders... looks like that may not be an issue any more!
