Stage6 R/T Crankshaft Bearings (Steel Cage) + FKM Oil Seals

High-quality crankshaft bearings and oil seals are essential for any performance-oriented engine. Stage6 has upgraded their bearing kits by combining robust SKF bearings with their new orange FKM oil seals from the R/T series – visually striking and engineered for durability.

Designed for Minarelli / Minarelli Replica 2-stroke engines. Please verify dimensions before ordering.

Metal vs. Polymer Cage Bearings

• Metal cage (this version): Best for daily use, long-term durability, ideal for stock and tuned street engines.
• Polymer cage: More flexible and lower friction, recommended for pure racing setups.

Both bearing types are SKF-certified for speeds up to 20,000 rpm, provided they are properly lubricated and installed.

The new Stage6 FKM seals offer reduced friction, higher efficiency, and significantly improved lifespan compared to older seal types.
