Stage6 Racing Drive Variator Pulley Minarelli

Stage6 Booster variator fixed pulley
Stage6 offers here the Racing Drive fixed variator pulley for MBK Nitro / Booster, made from CNC-machined aluminum with an optimized flank angle. 

Numerous tests were conducted before reaching this final version to ensure a high-quality technical product. 

Designed in CNC aluminum, its completely smooth surface, thanks to its specialized treatment, provides an improved finish and enhanced performance. 

The cooling fins have been removed to reduce air friction on the pulley. Additionally, since the part is lighter than the original pulley, it achieves better overall variator performance. 

This variator pulley is perfect for drag racing enthusiasts due to the absence of cooling fins. If you still wish to cool your transmission, we also offer the ventilated STR8 kick-start cover (for Nitro only) as an add-on.
