Vespa clutch/ crankshaft kit
German scooter specialist SIP Scootershop has this new 115 mm geared disc valve Vespa clutch/crankshaft kit available for Vespa 200 Rally/P200E/PX200 E/Lusso/'98/MY/Cosa 200 applications.
Features include 23 teeth, four SIP CR80 plates, ten springs, 60 mm stroke, 110 con-rod - for the "perfect connection between the crankshaft and the clutch on all Vespa largeframe models," says CEO Ralf Jodl.
"Piaggio designed these engines with a cylindrical flange, a spring washer and an M12 nut holding the crankshaft and clutch together. Generally speaking, this arrangement works quite well in a standard engine. Nowadays though, this tested set-up is not quite capable of reliable transmission of the power outputs that have become achievable.
"To solve this, we can now present a solution with the important advantages over the stock design - such as interlocking cog-teeth connection, simple de/mounting and a solid and enduring connection, for all mileages and power outputs.
"We now have a range of crankshafts and complementary clutches available with interlocking connections that are extremely solid and stable in operation. This technology has already been established in our BFA 306 engine design. These performance engines are easily capable of power outputs of up to 72 PS!
"When stripping such an engine, following operation, the clutch can be removed by hand once the holding nut had been undone, with absolutely no wear discovered. These achievements led us to transfer this advanced idea to more conventional engine casings, set-ups and clutch concepts.
"All SIP crankshafts and clutches equipped with this interlocking connection are compatible with each other. With this system, the components are locked together and held in position by the M14 holding nut, eliminating the need for a woodruff key.
"On original engine casings, a 3.5 mm thick spacer disc must be positioned between the clutch and bearing, with our SIP BFA engine casings, a thinner 2.5 mm spacer disc is used.
"The end result is a complete solution that eliminates once and for all one of the weakest links in the Vespa largeframe engine's drivetrain."
