Description
Stage6 R/T Crankshaft Bearings + Oil Seals C4 polymer cage (milled down outer ring) Piaggio, high-end racing main bearings with 1.1mm milled down outer bearing ring.
Racing bearing and oil seal kit by Stage6 R/T, for Piaggio NRG / Runner. Polymer cages have higher elasticity and reduced friction, designed for use with full-circle racing crankshafts and tuned / high performance engines.
You'll notice that the outer bearing rings are milled down a little (1.1mm). The resulting little gap between bearing and crank web allows for excellent lubrication.
Designed for high-end racing use.
Crankshaft bearings for motorcycle, scooter and moped
Crankshaft bearings ensure the smooth operation of engines, whether on scooters, motorcycles or mopeds. The crankshaft is an integral part of the engine and the associated bearings and seals must be in perfect condition.
A crankshaft bearing set consists of ball bearings and oil seals. They are usually sold as a complete set and must be replaced each time the crankshaft is installed/re-installed.
What are the symptoms of defective crankshaft bearings?
The main symptoms of a defective crankshaft bearing are:
- Unusual metallic noises coming from the direction of the crankshaft.
- Unusual vibrations of the vehicle.
Defective bearings must be replaced immediately, otherwise there is risk of further damage to the engine. There are many different tools for crankshaft removal or bearing pullers.
You can see how to change crankshaft bearings in our crankshaft disassembly and assembly tutorial.
Tuning Level: High End racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.
Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.
