This is a new CNC machined front miter box input shaft for a 2 wheel drive Rokon motorcycle. This is the shaft that connects to the universal joint inside the main frame tube. The shaft is 4 13/32 inches long. 3 new 3/16 diameter split pins are included. This shaft works with screw in and bolt on miter cap miter boxes. It is not correct for the newer snap ring miter boxes. This will not work in a Plunger transmission or a rear miter box. The A1127 is no longer supplied with a snap ring or snap ring groove. An A1182 #108 miter box spacer can be used to replace the spacer and snap ring if required.
