Stage6 R/T Minarelli crankshaft bearing kit
It is important to ensure high quality for crankshaft bearings and oil seals on high-performance engines. Stage6 R/T has updated these kits, pairing their top-quality bearings with orange Stage6 R/T FKM oil seals – a unique style for proven reliability!

Stage6 R/T advantages
These orange FKM crankshaft oil seals are manufactured using the most modern production technologies. Stage6 R/T has focused on reducing friction to improve engine performance and the service life of the crankshaft bearing and oil seal kit.

The bearings are available in 2 versions:

• With a polymer cage for lower friction, geared more towards racing use.
  
• With a more robust metal cage, for daily road use of your two-wheeler.

Both types are SKF-approved for use up to 20,000 RPM.

This version with a TN9 polymer cage reduces friction and allows for higher speeds. They are mainly recommended for use with racing-type engines. The bearings have a heat resistance limited to 120°C. It is therefore important to properly tune your carburetor to avoid damaging the polyamide cage.

Please note:

• For engines with catalytic converters, favor the metal cage bearings, which have better heat resistance.
  
• Please also pay attention to the installation direction: the semi-open cage must be installed facing the crankshaft (markings on the oil seal side).
