Description
Stage6 R/T high-end crankshaft for Piaggio scooters
Stage6 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 crankshaft
Meticulously balanced high-end racing full circle crankshaft with light alloy inserts, which can be used with cylinders with 85mm 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 Piaggio
The Stage6 R/T crankshaft was developed as the perfect complement for 80cc – 85cc racing cylinders with 85mm connecting rod length. It is also suitable for increasing displacement.
The Stage6 crankshaft from Piaggio has wider crank webs than the original model. It is therefore necessary to machine the crankcase to fit it in. The final dimensions of the crankcase after machining should be 76.8 mm (+ 0.2 mm).
Please note: The variator-side stub is smooth and has a larger diameter than classic crankshafts (16 mm). You must therefore use the Stage6 R/T Piaggio variator and also the 16 mm washer, the 16 mm CVT sleeve and the 16 mm ramp plate.
