Folan Engineering, who makes some very lightweight and powerful motors, teamed up with ISR to produce this beautiful 90 degree 650cc vtwin motor. Not much information out there on this just yet. The 1050cc Folan V-twin motor weighed in under 90lbs. Folan has made motors for Highland and Cannondale, hopefully this ends up in lightweight racer.
