In collaboration with Massimo Tedeschi, Stage6 developed this Stage6 R/T Crankshaft MKII Piaggio with 90mm connecting rod, originally designed for use with Stage6 R/T cylinders.

Stage6 re-engineered and improved the balancing of their R/T crankshafts; anodized orange aluminium pads reduce weight and the counterweight inserts are made of HQ Tungsten alloy. You can expect a power increase of 0.5hp and a slightly wider rpm range.

The variator-side spline was reinforced for improved reliability and has a 20mm diameter (same as main bearing). A matching Viton oil seal is included.

In case you need help, there are some tutorial videos on how to install the Stage6 R/T MK II crankshaft on our website.

For Piaggio NRG / Gilera Stalker.
