When it comes to high-performance engines, the quality of crankshaft bearings and oil seals plays a vital role in performance. Stage6 has taken it a step further by pairing their premium SKF bearings with bold orange FKM oil seals from the Stage6 R/T line, offering both a striking appearance and superior performance.

This kit is designed for scooters with Piaggio engines, but make sure to check the dimensions before placing your order.

Crankshaft Bearing Options :

Polymer Cage – Best suited for racing applications. It offers more flexibility and reduced friction compared to metal cages.

Metal Cage – Ideal for regular street use. It’s more durable and better suited for long-term stress.

Both versions are SKF-approved and can handle speeds up to 20,000 RPM. Proper lubrication and installation are key for long-lasting performance.

Why Choose Polymer-Cage Bearings :

Polymer bearings offer increased elasticity and reduced friction, making them a great choice for racing engines. However, they require attention to carburetor and ignition settings, as they are only rated to heat up to a maximum of 120°C to avoid damage to the plastic cage. Note: Only use the polymer cage version on engines without a catalytic converter!

Installation Tip :

When installing the bearings, make sure the half-open side faces the crankshaft webs.

The new orange FKM oil seals are made with cutting-edge technology, providing a longer lifespan and lower friction compared to older models, boosting engine efficiency.
