Product description
The perfect connection between the Clutch and the Crankshaft for all Vespa Largeframe models.
As standard, the crankshaft and Clutch on Vespa Largeframe models are connected via a cylindrical Flange, a disc spring, and an M12-threaded Nut. For the most part, this works quite well. However, this connection is not designed to handle the power output typical of engines with modern tuning concepts. That’s why we offer a solution with the following advantages:
- Connection via gear teeth
- Easy installation and removal
- A secure, low-wear connection for any mileage and engine power
We offer a series of crankshafts and Clutches that feature a very stable toothed connection between the components. This type of fastening has already proven itself extensively in the BFA 306 engines for Vespa Largeframe models. In those applications, power outputs of up to 72 PS were achieved. After loosening the nut, the clutch could be removed and reattached without applying force. No wear was observed. Therefore, we decided to offer this type of power transmission for conventional engines and clutch designs as well.
No Woodruff Key, but with an M14 thread
All SIP clutches and crankshafts featuring our toothing can be combined with one another. The parts are simply slotted together; no locking key is required. To ensure the connection is securely fitted, it is locked in place with an M14 flanged nut.
A washer is placed between the Clutch and the Bearing. For original casings, this washer is 3.5 mm thick; for SIP-BFA casings, a 2.5 mm thick washer can also be used.
Note: The oil pump gear cannot be installed.
Conclusion: A permanent solution that eliminates a weak point in Vespa large-frame engines once and for all.
