Description

Polini Crankshaft "Evolution" MBK Nitro / Aerox with 44mm stroke and 85mm connecting rod for 12 + 13mm piston pin for Minarelli horizontal AC / LC "Hyper Racing" engines.

It was developed to go with Polini's 94cc Evolution cylinders. This 2010 version has a "long" 44mm stroke and an 85mm connecting rod for 12mm + 13mm piston pin. Full-circle crankshaft (with counterweight inserts) with special reinforced TiN-coated connecting rod and a 16mm smooth spline (variator-side). Because of this 16m smooth spline, it can only be used with Polini's Evolution variators, for other variators you'll have to order additional parts.

For MBK Nitro / Aerox / 44mm stroke - 85mm connecting rod - 12 + 13mm piston pin.
13mm small end bearing is included, main bearings and seals are not included.

Questions about the product
 
 
Notes and Safety

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.
