Bidalot has been known for 50cc tuning and racing components for several decades. The Racing Factory series (RF WR) includes Bidalot's high-end products and is the brand's most powerful series to date.

The series is available for various displacement classes. The Racing Factory products go to the absolute performance limit in all categories.

Racing Factory range

You can equip your bike completely with Bidalot Racing Factory parts and build yourself a high-end racer. Here is a list with Racing Factory parts:

• Crankshaft Bidalot RF
• Bidalot RF internal rotor ignition
• Clutch Bidalot RF
• Exhaust Bidalot RF

Of course, you need a bit of know-how to install the racing parts correctly and adjust them to yield maximum power.

To get the full potential out of your engine, we recommend buying a high-quality carburetor with the right diameter for the selected displacement.
Also remember to adapt the chassis to the increased engine power, e.g. with improved brakes and suspension.

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.
