One of only four E-95’s created, the A.J.S. E-95 is a modified version of the A.J.S. E-90 horizontal twin motor, and was called the porcupine because of the spiky cooling fins protruding from the cylinder heads.

Originally designed to be supercharged, those plans had to be scrapped when the FIM banned supercharging in 1946. Despite its reputation for not living up to its hype, a finished Porcupine is valued somewhere north of a $250,000. Pictures and more after the jump.
