Cylinder Italkit 140cc ø57mm Aprilia engine Rotax 122/123 2T

Cylinder Aprilia rs 125 2001 valid for Rotax type 122 engines, increases the displacement to 140cc in these already very powerful engines.

With this you will achieve a much fuller engine at low revs, greater response at mid-range, and an improved "kick".

Very important is the corresponding carburetion adjustment, as these engines are very sensitive and delicate to excessively lean carburetion.
