Well its definitely not a straight fit. the swing arm pivot on the 28 is much larger. the threaded part that screws into the left hand side of the frame is bigger. The only way it would fit is by using the 21 pivot bolt and spacers and hope that they fit the proarm. I dont have the 21 pivot bolt or spacers, just the bare frame. then ya got to wonder why they made it bigger??

differences between mc21 and mc28 frame.

28 has extra lugs for the tail fairing to screw into below the subframe mount.
28 has a large cut out behind the headstock to mount the electric lock.
28 has a much bigger swing arm pivot and pivot thread.

can anyone tell me if the 21 spacers and pivot will slip straight into the pro arm?
