Crankshaft Stage6 R/T Piaggio scooter stroke 44mm connecting rod 90mm

Now available, the Stage6 R/T crankshaft with a 90mm long connecting rod and a 44mm stroke! Like all Stage6 R/T crankshafts, the 44mm stroke version is also optimized to improve gas flow and meet the toughest competition demands. The Stage6 R/T crankshaft stands out for its forged 90mm connecting rod, reinforced 18mm connecting rod pin, silver thrust washers, and a silver Torrington needle cage. Since the shaft on the variator side has a diameter of 16mm and is thicker, this crankshaft must be combined with a Stage6 Oversize, Malossi MHR Overrange, or Polini Evolution variator. The delivery includes two needle cages, which allows the installation of pistons with a 12mm or 13mm pin. The new Stage6 R/T crankshaft with a 90mm connecting rod and 44mm stroke is not only the ideal crankshaft for the new Stage6 R/T Big Bore cylinders, but also a true alternative to the expensive Malossi MHR BigBore crankshafts. NOTE: For Piaggio engines, a special 20mm seal must be installed, which is included in the kit!!! NOTE! 44mm stroke, 90mm connecting rod!

NOTE! To use this crankshaft, it is mandatory to install a lightened flywheel or, alternatively, a rotor, since using any other type of flywheel may affect the crankshaft and completely voids its warranty, as it is intended exclusively for competition use.

Attention! You must carry out balancing checks before installing it in the engine, since manufacturers will deny warranty for any balancing fault found after installation.
