Advantages of Stage6 R/T tuning crankshaft
Meticulously balanced high-end full-circle crankshaft with tungsten inserts that can be used with cylinders with 90mm connecting rods and 44mm stroke.
The tuning crankshaft features precision manufacturing and adherence to tight tolerances. The forged, then CNC-milled connecting rod is extremely resistant and offers maximum strength for use in racing engines, while at the same time optimizing the flow characteristics.
The very precise balancing via high-quality tungsten inserts prevents strong vibrations and ensures smooth engine running. The top-of-the-line crankshaft comes with a top quality small end bearing.
Fitting the Stage6 R/T crankshaft for MInarelli
The Stage6 R/T crankshaft was developed as the perfect complement for the Stage6 R/T Big Bore 95cc cylinder, but can of course also be used with other racing cylinders with 90mm connecting rod, e.g. with the 2Fast 94cc, the Bidalot WR 88 or the Malossi Testa Rossa 94.
The crank webs of the Stage6 R/T crankshaft have a larger diameter than the original model. Machining of the crankcase is therefore necessary. The final dimensions of the crankcase after machining should be 76.8 mm (+ 0.2 mm).
When installing, make sure to use a new pair of crankshaft bearings and seals.

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.
