Part 1 of 3

Genuine Aprilia sprag clutch housing (outer race) -AP0659123 (ex AP0659120) (ex AP0659121)

For '98-'03 Mille, Mille-R, '00-'03 Falco, and '02-'05 Tuono.

If you can hear your starter motor spinning but the engine is not turning over, the sprag clutch assembly has failed.

The hard starting nature of some V990s causes a tremendous strain on this assembly.  The sprag clutch is a unidirectional starting system which prevents grinding the starter.  Unfortuantely, this assembly is also very susceptable to damage if the starter is run over and over again while attempting to start an unwilling engine.

The installation of this assembly is an advanced operation, if you are not comfortable with torque specs and adjusting your own valves, you should not attempt to install this assembly.

***Please note: This part is not to be used on '04-'08 RSVR, Factory, '06-'08 Tuono R, '01-'04 Futura, nor '01-'06 Caponord.  For those models you need Part # AP0659550, which is no longer available

Part no 4 in the Diagram.
