Cylinder Bidalot RF80WR Derbi euro 3
We are always looking for more power and improved performance, 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 cylinder kit Bidalot Racing Factory 80 WR Derbi Euro 3 / 4 is another milestone in 2-stroke tuning, with improved cooling and very high life expectancy. Thanks to CAD manufacturing, the highest precision has been achieved.
The Nikasil-coated aluminum cylinder has 6 transfer ports and a boost port supported exhaust. Bidalot developed complete new transfer and exhaust ports to perfectly match the Ø47.6mm bore. The objective was to provide very high power at high rpm, but without compromising torque and mid-range performance.
The piston is made of an extremely heat-resistant aluminum-silicon alloy for extended service life.
The one-piece cylinder head is CAD designed and has a self-centering combustion chamber. The cylinder head protrudes 2.4 mm into the bore. The water jacket has been redesigned and adapted to the new ports. The material thickness is constant throughout to ensure consistent thermal stability. The exhaust is flushed directly, and the water then flows to the cylinder head, where it cools the combustion chamber, thus ensuring perfect overall cooling.
Timing and compression are designed for racing use (±193° exhaust, ±132° overflow, with a compression ratio of 15.8-16.0 to 1).
Note: when installing this racing cylinder, you have to use matching high-end tuning components - reinforced racing crankshaft (with 90mm connecting rod and 44.9mm stroke), internal rotor ignition, VForce reed valve, larger carburetor (32mm), reinforced clutch, etc. Since this is a real high-end part, you should definitely have the appropriate know-how!
The cylinder is installed with a special 4-hole flange, but can also be installed with a 2-hole flange with 50mm hole spacing.

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.
