Airsal 70cc 47.6mm Cylinder Kit – Morini LC – Aprilia SR2000 / Suzuki Katana

The Airsal 70cc cylinder kit is a performance upgrade for Morini liquid-cooled (LC) 2-stroke engines. With a 47.6mm bore, this kit delivers approximately 70cc displacement and noticeably more torque compared to the stock 50cc cylinder.

Made from aluminium, it offers excellent heat dissipation and improved reliability over cast iron cylinders. This makes it well suited for daily use.

The Airsal 70cc is known for its strong acceleration and smooth mid-range power. It is not an extreme racing cylinder, but rather a reliable and affordable sport cylinder with excellent value for money.

Compatible with the original exhaust. For optimal performance, adjusting the main jet or upgrading to a 17.5mm carburetor is recommended.
