Cylinder Airsal Alu Sport 80cc Derbi Euro 3 / 4

The "big bore" version from Airsal.

The main feature that sets this Alu-Sport apart from the rest is that it comes equipped with a 50 mm diameter piston from the same brand and 2 rings, which brings it up to 80cc.

Another notable difference is the exhaust port, which in this case is more open and refined.

Finally, it is made of aluminium/nicasil and has 5 transfer ports. Power at a very good price!
