Description
Stage6 R/T high-end racing crankshaft 47mm stroke / 100mm connecting rod Malossi C-One & RC-One
Stage6 presents this high-end crankshaft for scooters with Malossi C-One / RC-One crankcase or comparable tuning crankcases. It has been specifically developed for the Stage6 R/T 100 FL cylinder kit and meets the requirements of modern 100cc FL racing engines. This architecture ensures optimized engine geometry, precise alignment and efficient power transmission.
Features Stage6 R/T crankshaft Derbi
- Hot-forged 18NiCrMo5 steel (HRC): Maximum reliability and strength.
- CNC-machined connecting rod with double heat treatment: High durability under heavy load.
- Precision grinding and polishing: Excellent surface finish and improved lubrication.
- Optimized balancing with high-density tungsten inserts (17.6 g/cm³) and ultra-light connecting rod (<80 g): Minimizes vibrations and ensures smooth operation even at very high RPM.
- Runout check on every crankshaft with a maximum tolerance of 0.02 mm.
- Cold-rolled threads: Increased durability.
- Silver-plated needle bearing: Reliable operation at very high engine speeds.
Compatibility and installation tips Stage6 crankshaft
The racing crankshaft is a perfect match for the Stage6 R/T FLR 100 cylinder kit for Malossi C-One / RC-One, but is also an excellent choice for all similar high-end cylinders with 47mm stroke / 100 mm connecting rod.
Important note for installation : Before installation, clean the crankshaft thoroughly with fuel to remove the protective oil. Machining of the engine case between 82.5 and 83 mm is required, and connecting rod clearance must be checked. This crankshaft also requires a specific 20mm oil seal on the variator side instead of 19 mm (ref. S6-8039005/OR). It is also recommended to use a new Stage6 R/T crankshaft bearing kit for Piaggio.

How to change a crankshaft?
The crankshaft is one of the main components of the engine and is responsible for the smooth operation of motorcycle, scooter and moped, whether with two-stroke or four-stroke engine. The longevity of the engine depends not only on the proper condition of the crankshaft, but also on the fact that it is properly mounted.
For a correct installation of the crankshaft, we recommend our tutorial: Crankshaft disassembly and assembly.
How can I tell if my crankshaft is Damaged?
A broken crankshaft causes metallic noises, unusual vibrations, leaking oil seals and drastically reduces the performance of the two-wheeler. In any case, the vehicle must be stopped immediately to prevent the damage from getting worse.
Please note that whenever the crankshaft is changed and serviced, you'll have to install new crankshaft bearings.
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.
