Description
We are always looking for more power, more performance and more speed, and tuning expert Bidalot from France is definitely one of our go-to manufacturers when it comes to high-quality, extremely powerful racing products. The Bidalot Racing Factory 50cc WR Derbi Euro2 cylinder kit is another milestone in the high-end 2-stroke tuning.
The Bidalot RF50WR racing kit is a powerhouse inspired by and developed for racing, and has been successfully tested on international racetracks. The name RF-WR (WR = world record) refers to the 2018 world speed record on Lake Bonneville, USA.
The Nikasil-coated aluminium cylinder has 5 transfer ports and an exhaust plus boost ports. Cylinder bore is 40mm. The cylinder head has a special coating and provides excellent cooling of the self-centering combustion chamber. The piston is made of a very heat-resistant aluminium-silicon alloy for extended service life.
Attention: this high-end tuning cylinder has to be run with other appropriate high-end tuning components (internal rotor ignition, 28 or 30mm carburetor, V-Force reed valve, reinforced clutch); you also need the matching Bidalot crankshaft with 39.7mm stroke and 85mm connecting rod. If you don’t want to go all the way, we recommend to use the regular Bidalot RF50WR version (lower compression).
Technical Specifications:

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 Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
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.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
