The original cylinder head can still be used with this cylinder kit. The ECU CDI unit 171.0015 is required for operation with Euro3/4 vehicles. The ECU CDI unit 171.0017 is required for operation with Euro5 vehicles.

Thanks to a special steel liner with nickel-carbide-silicon coating and the "HTR" ring (High Turbulence Ring), the bore has been enlarged to 77 mm, increasing the displacement from 278cc to 294cc. The piston has a wider skirt. The crankcase does not need to be machined for this cylinder kit.
