Crankshafts
We use Kingwelle crankshafts because we are convinced of the quality, workmanship and durability. We have a very closed communication to the manufacturer, so that our wishes and suggestions for improvement can be realized immediatetly.
The new cranks ("Nuovo") are equipped with improved seals, which can be changed from the outside! No dissambling of engines because of worn out seals anymore. Seals and needed bolts/ screws are supplied with the crank. The 2018 version is thermally surface-treated and nitrated.
