Cylinder Airsal XTreme 80cc Derbi (D50B0)
If you are looking for the top cylinder from Airsal, this is it: Cylinder Airsal X-Treme 80cc Derbi Euro3 (D50B0).
It has a 50mm bore and is designed for crankshafts with original stroke, which brings it close to 80cc. As usual with Airsal, the cylinder is made from high-quality aluminum and the bore is coated with Nikasil. It comes with no less than 6 transfer ports and a bridged exhaust port. New in the 2014 version are additional boost ports at the exhaust, which support the cylinder in the upper RPM range.
You should optimize your setup to get the most out of this cylinder:
- 28mm carburetor (PWK / VHST), e.g. the Stage6 R/T
- High end racing exhaust
- Internal rotor ignition
contents Airsal Xtreme 80cc
- 80cc aluminum cylinder, bore = 50mm, 7 transfer ports and bridged exhaust
- 50mm Vertex piston with 1 piston ring and 12mm piston pin
- High compression cylinder head, one-piece
- Gasket set for sealing and squish adjustment
Note: 50cc bikes with Derbi Euro 4 engines use a slightly smaller temperature sensor (thread: M12 x 1.5) than the Euro 3 models (M14 x 1.5). To fit the smaller Euro 4 sensor to the cylinder head, you also need the MF96.91010 adapter.
Note 2: As seen in the last picture, there is a small gap between the cylinder head and the cylinder, but this is normal for this model, as the cylinder head gasket is thick enough to prevent any coolant leakage.
