This engine was the proposed powerplant for the SBF-1, a concept that a few of my old sport bike forum buddies and I came up with. The idea was to create a completely unique sport bike design, but it never really came to fruition. The engine however, was my favorite part of the process. I used cylinder geometry from the Yamaha R-1, and the 3 cylinder design of the Triumph Speed Triple.
