Kloķvārpsta Stage6 R/T gājiens=44mm / konrods=90mm / virzuļa tapa=14mm Piaggio NRG / Runner

Stage6 R/T Crankshaft Piaggio NRG / Runner with 44mm stroke and 90mm connecting rod for 14mm piston pin.

HQ full-circle crankshaft for higher primary compression (HPC) with excellent balancing, with silver-plated thrust washers and TiN-coated 90mm connecting rod. It has a longer stroke than the original crankshaft (4mm longer).

Originally developed for use with Stage6 R/T 95cc cylinders, but it can also be used with other large displacement cylinders such as 2Fast 86cc or Polini Big Evo 94cc or Malossi Big Bore 86cc (with 5mm cylinder spacer and matching needle cage).

Note: the variator-side spline is smooth and has a larger 16mm diameter; this means that the only variators that can be mounted with this crankshaft without any additional modifications are the Polini Evolution variators. You can also combine it with Stage6 R/T and Malossi MHR GP variators, but you’ll need a different ramp plate and sleeve (item no. S6-56166ET012 and S6-56166ET016 for Stage6, M2512807B and M2312806B for Malossi).
