DescriptionCrankshaft -MAZZUCCHELLI Racing (rotary valve)- Vespa PX125, PX150Description In order to achieve higher speeds, one should reach for the racing shaft. The extended intake timing results in a much freer engine revs. This measure is especially noticeable with high-revving cylinders.The quality of the crankshafts is very good and so they resist even the highest revs. Especially for engines with a larger displacement, they are an optimal supplement to extend the usable speed range.These engines run out freely, which leads to a significant increase in top speed.Bearingssizes:15x19x20mmGudgeon pinsdiameter:15 mmCrankshaftsstroke:57 mmthread rotor side:M12x1,25 right-hand threadthread drive side:M12x1,5 right-hand threaddiameter crankwebs:98 mmwidth crankwebs:38.8 mmdiameter bearing seat rotor side:25 mmdiameter bearing seat drive side:25 mmdiameter oil seal seat rotor side:24 mmdiameter oil seal seat drive side:31 mmfull circle crankshaft:rotary valve crankshaft:length rotary crankweb:193 mmVespa PX125-150 - intake timing for long rotary surface (33mm) (°):172Vespa PX125-150 - intake timing for short rotary surface (53mm fully modified) (°):196crankcase has to be milled:engine casing has to be modified:Connecting rodslength connecting rod:105 mmthickness connecting rod:5.3 mmdiameter small end connecting rod eye:19 mmlubricating hole at small end bearing:nodiameter crankpin:22 mmlubricating hole at crankpin bearing:notchcrankpin shims:yes Model / manufacturerccTypeEngineYear of constructionAdditionLML Star 125 2T/ DLX / Via Toscana / Deluxe1252T ACLML Star 150 2T / DLX / Via Toscana / Star / Stella / Belladonna RV1502T ACMOTOVESPA 125 CL1259CL2T AC'78-MOTOVESPA 150 CL1509NC2T AC'78-VESPA 125 GTR125VNL2T2T AC'68-'78145901 ->VESPA 125 TS125VNL3T2T AC'75-'7818139 ->VESPA 150 Sprint Veloce150VLB1T2T AC'69-'79294260 ->VESPA 150 Super150VBC1T2T AC'65-'79412374 ->VESPA COSA 1125VNR1T2T AC'88-'91VESPA COSA 1150VLR1T2T AC'87-'90VESPA COSA 2125VNR2T2T AC'91-VESPA COSA 2150VLR2T2T AC'91-VESPA P125X125VNX1T2T AC'77-'82VESPA P150 S150VBX1T2T AC'78-'90VESPA P150X / PX150 E150VLX1T2T AC'78-'85VESPA PX125 2011/ 30 Jahre125ZAPM741002T AC'11-VESPA PX125 CAT125ZAPM501002T AC'07-VESPA PX125 E125VNX1T2T AC'81-'83VESPA PX125 E '98 / Millenium125VNX2T2T AC'98-'05VESPA PX125 E Lusso/EFL/Arcobaleno / Elestart125VNX2T2T AC'83-'97VESPA PX150 2011150ZAPM742002T AC'11-VESPA PX150 E '98 / Millenium150VLX1T2T AC'98-'05VESPA PX150 E Lusso/EFL/Arcobaleno / Elestart150VLX1T2T AC'83-'97
