kickstart gear / castle washer 34.5x17 for Aprilia, Gilera, Piaggio, Vespa

Kickstarter drive (star washer) is the other side of the kickstart shaft. That sits on the crankshaft in front of the Variator and the teeth wear out over time, which leads to problems with the kick starter. Should be changed as soon as possible. Suitable for 17mm crankshaft mount. OEM-No. for comparison purposes: 235060 / 435060 / 478032
