Designed to fit into the BSA pre unit gearbox shell, either standard or RR2 type. It comprises of all the internal components for conversion to a five speed gearbox, the only original parts retained are the selector shaft and the selector pawl mechanism which connects directly to the gear lever. Gear change pattern is the same as for the RRT2 gearbox. The RRT2 speedo drive and standard kick start ratchet gear are retained, so that the gearbox may be used for both road and racing use.
