Crankshaft Stage6 R/T 44mm stroke / 90mm conrod Piaggio / Vespa

Video Description Stage6 R/T high-end crankshaft PiaggioStage6 R/T crankshaft for 50cc scooters with Piaggio engine in flow-optimized design. Fits many 50cc scooter models such as Piaggio Zip, Typhoon, Nrg, Gilera Runner, Stalker, Vespa 50 2T or Aprilia SR 50 (Piaggio engine).Stage6 R/T tuning crankshaftMeticulously balanced high-end racing full-circle crankshaft with light alloy inserts, which can be used with cylinders with 90mm connecting rods with 44mm stroke.The tuning crankshaft features precision manufacturing and adherence to exacting tolerances. The forged, CNC-machined connecting rod is extremely resistant and ensures maximum strength when used in racing engines, at the same time its design optimizes flow dynamics for enhanced performance.The very precise balancing via lightweight metal inserts mitigates strong vibrations and ensures smooth running. The top-of-the-line crankshaft comes with a top quality small end bearing.Fitting the Stage6 R/T crankshaft PiaggioThe Stage6 R/T crankshaft was developed as the perfect complement to the Stage6 R/T Big Bore 95cc cylinder, but can of course also be used with other racing cylinders with 90mm connecting rod length, such as the 2Fast 86cc cylinder (90mm connecting rod) or the Malossi Big Bore 86cc and Polini Big Evo 94cc cylinders, in this case you'll have to use a 5mm cylinder spacer and a new small end bearing.The Stage6 Piaggio crankshaft has wider crank webs than the original model. It is therefore necessary to machine the crankcase. The final dimensions of the crankcase after machining should be 76.8 mm (+ 0.2 mm).Please note: The variator side stump is smooth and has a larger diameter than classic crankshafts (here 16 mm). You must therefore use the Stage6 R/T Piaggio variator and also the 16 mm washer, the 16 mm sleeve and the 16 mm ramp plate.TECHNICAL DETAILS FOR STAGE6 R/T Piaggio scooter crankshaft:Stroke: 44 mmConnecting rod length: 90 mmPiston pin: 14 mmNeedle cage: 14x17x16.6 mmMachining crankcase: 76.8 + 0.2 mmSupplied with CVt nut: M12x1.25 mmSupplied with an oil pump pinion d.16 mmSupplied with crankshaft seal Stage6 made of VitonFor Piaggio LC and AC Questions about the product
