Genuine Aprilia motorcycle sprag clutch outer, part number AP0659550, item 10 in the diagram.
Some V990's suffer from hard starting which in turn can mean the sprag clutch is under a lot of strain. The sprag clutch is a one way freewheel/clutch which basically prevents grinding of the starter motor. It engages when the starter motor is driving the engine but freewheels once the engine starts.
Please note that if the starter is turned over and over during start up, with no effect, it too can become damaged.
Replacing the sprag clutch is no mean fete and so if you are unsure at any stage, please email us or call us at the shop and we'll be happy to discuss your concerns.
Alternatively, we can book your bike in for us to complete the task in our fully equipped workshop
