Norton 5 Speed Close Ratio Gear
Set

                          To Fit Standard AMC Cases

<< back to products

These are recommended only for use with 500cc engines, eg. Manx Norton, G50's, Matchless, Weslake and Norton 500 twins.  As these require a different length mainshaft, it is essential we know which machine they are for when ordering.

We have been asked on numerous occasions if they are suitable for Norton Commando Twins.  Whilst we do not sell them on this basis, fitting with an outrigger bearing may make there use possible, however Nova would accept no responsibility for damage caused to them.

The gear sets comprise of both shafts with all gears, sleeve gear runs on needle roller bearings, selector forks, selector plates with drive gear and selector quadrant.
