Description

EVO advance shaft for Vespa 90-125/PV/ET3/PK/S for Vespa 90-125/PV/ET3/PK/S/XL/2 rotary disc valve, stroke: 51.0mm, connecting rod: 97.0mm , 20/20mm cone, M12 for competition only! Not permitted in the German StVZO zone! Highlight of the EICMA 2010 the new Evolution crankshaft. has returned to its roots. The racing shaft is a very high quality and cleanly made slide valve motor. It is particularly balanced and equipped with tungsten balancing weights. The connecting rod is equipped with upper and lower lubrication holes/slots for optimal lubrication and is massively reinforced. Quality stress proof and lubrication are really in the foreground here. More time allows for a larger fill and more power. Molded balance weights with additional balance holes are sealed with resin. What comes out is a very quiet engine, with less vibrations. Result: high-end crankshaft for all those who do not want to drive disc packs. Shaft stroke / 51 mm stroke / 97 mm connecting rod / 20/20 mm / M12 Crankshaft stroke with 82 mm generator web, 87 mm valve web slides, balanced, 97 mm connecting rod, suitable shaft seal 20 mm, suitable bearing 20 mm, chamfered / cone thickness with M12 thread, includes SIP-TIP connection bearing: ideal for Evolution stroke or cylinder.
