Description
Piston 39.95mm Bidalot RF50WR Derbi.
Bidalot is a French producer of tuning and racing parts with over 100 championship titles.
The piston with piston ring(s), piston pin and circlips is the moving heart of the cylinder. Due to the constant up and down movement, the piston is subject to wear. At some point the tolerances are no longer correct, the piston ring no longer seals perfectly and the performance decreases, i.e. the piston must be replaced.
Technical details:
- Displacement: 50cc
- Piston pin: 12 mm
Bidalot Racing Factory
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:
- Cylinder Bidalot RF WR 50cc to 96cc
- 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.
When to replace the piston?
To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).
Extending Piston life
To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.
It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
