Airsal Sport 70cc Cast Iron Cylinder Kit – Derbi Euro 3 (D50B0)

The Airsal Sport 70cc Cast Iron Cylinder Kit for Derbi Euro 3 (D50B0) engines offers the proven reliability of cast iron with Airsal’s signature performance and value. Known for their high-quality aluminum cylinders, Airsal delivers an excellent alternative here — a durable, long-lasting cast iron cylinder that’s perfect for everyday riders and sport setups alike.

Performance

This cylinder provides strong torque and impressive power, especially in the mid-range, resulting in excellent acceleration and pulling power. It’s ideal for riders who want dependable performance without sacrificing durability. The kit works perfectly with original or touring exhaust systems, and can also be used in a mild sport setup with a larger carburetor and sport exhaust.

Installation Note

To install this cylinder, you’ll need 120mm studs, as the one-piece cylinder head requires the studs to extend beyond the head. Please note: 50cc bikes with Derbi Euro 4 engines use a smaller temperature sensor (M12 x 1.5 thread) compared to Euro 3 models (M14 x 1.5).

Kit Includes

• 70cc cast iron cylinder
