Crankshaft Stage6 R/T connecting rod 85mm Minarelli horizontal
Description
Stage6 R/T high-end crankshaft with 85mm connecting rod
Stage6 R/T crankshaft for 50cc scooters with Minarelli horizontal engine with flow-optimized design. Fits many 50cc scooter models such as Yamaha Aerox / Jog, Malaguti F12 / F15, Aprilia SR50, and many more.
Stage6 R/T tuning crankshaft
Meticulously balanced high-end racing shaft with light alloy counterweight inserts that can be used with all cylinders with original stroke / original connecting rod length.
The tuning crankshaft features precision manufacturing and adherence to exacting tolerances. The forged, CNC-machined connecting rod is extremely resistant and ensures maximum strength when used in racing engines, at the same time its design optimizes flow dynamics for enhanced performance.
The very precise balancing via lightweight metal inserts mitigates strong vibrations and ensures smooth running. The top-of-the-line crankshaft comes with a top quality small end bearing.
The crankpin measures 18mm instead of 16mm to increase durability.
Fitting the Stage6 R/T crankshaft Aerox
The Stage6 R/T crankshaft was developed as the perfect complement to the Stage6 R/T 70cc cylinder for Minarelli horizontal, but can of course also be used with other racing cylinders with 85mm connecting rod length.
You can also use a cylinder kit with 80mm original connecting rods, in which case a 5mm cylinder spacer must be used.
Plug & Play installation - the Stage6 R/T shaft can be installed without further modifications, without the need for complicated crankcase machining. We recommend using a set of new crankshaft bearings.

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.
