Racing Crankshaft MAZZUCCHELLI

for Vespa PK125 ETS/N/XL/XL2
disc valve, stroke 51,0mm, conrod 97,0mm,
pin 15mm, cone 24/25mm, M12

FOR RACE USE ONLY

Racing crankshafts are a simple and effective tuning step for every disc valve engine. A racing crankshaft enables higher numbers of revs. The engine becomes more lively and agile. The high quality racing crankshafts from Italian company MAZZUCCHELLI convince thanks to their minimum production tolerances and limited bearing clearance. This guarantees high rev endurance and an exceptionally high product lifespan.

 

In contrast to the original crankshaft, a racing crankshaft has a clearly extended inlet time. This means the charge level is increased. The crank webs are flow-optimised and polished. Turbulence and flow separations are thereby reduced. A polished connecting rod and a lower connecting rod bearing as a silver bearing satisfy the highest aspirations. All crankshafts are supplied with upper connecting rod bearings.

Those who want to convert to electronic ignition should go for the 20/20mm racing crankshaft. In combination with a racing cylinder, the thicker and therefore more stable cone is recommended. The ETS crankshaft should be installed on high revving engines which are equipped with high performance cylinders or very light flywheels. This omits the risk of the crankshaft stump from being torn away. A set of conversion bearings and the corresponding oil seal are then required in the V50/PV/ET3/PK engine casings.

 

A strengthened connecting rod is fitted to the RACE version. Additional lubrication holes in the upper (on the 125 series only) and lubrication slots in the lower connecting rod eyelet lead to additional stability and allow higher numbers of revs due to the superior lubrication.

 

Conclusion: not only a good idea in combination with a tuning cylinder. A boost in performance can also be achieved with an original cylinder. MAZZUCCHELLI stands for long product lifetime and durability.

 

SIP community user '„NOSw11', Italy:

"Excellent! As I had previously installed a crankshaft with bronze bushing, due to the tuning I wanted to have a crankshaft with needle bearings under all circumstances. I therefore chose Mazzucchelli as I can be sure that their products are produced with the highest level of care and the price is right."

 

Racing crankshaft / stroke 51mm / connecting rod 97mm / 24/25mm, M12

Racing crankshaft with Ø 82mm crankweb (flywheel side), Ø 87mm crankweb (rotary valve side), 97mm connecting rod with 2 additional lubrication bores, oil seal housing 24mm, bearing housing 25mm, stump cone with M12mm thread, incl. connecting rod bearing

 

SIP-TIP: New bearings, oil seals and keys are a must. Same goes for sealing kit, clutch-, and flywheel nuts. When using a V50/PK/PV/ET3 crankcase, you?ll need a conversion bearing oil seal. It also makes sense to use the crankshaft tools # 27338000, # 21071000 and # 18119000. Ideal for POLINI, MALOSSI, DR and PINASCO racing cylinders with rotary valve.
