70cc Ø47mm kit complete with POLINI cylinder head 4 CAST FONTE studs Ciao, bravo, boss, grillo, si, superbravo...

If you are looking for a solid and efficient kit for your CIAO, then this set is for you! POLINI struck very hard by finally getting rid of the known defects of the PIAGGIO CIAO on a large cast iron cylinder!

1- Polini switches to a 4-stud system for greater robustness and more freedom in terms of ducts (which requires you to use POLINI 170.0201 casings

2- Polini uses a large diameter interchangeable exhaust ball joint that is well released: one in 22.3 diameter and one in 27mm diameter (we are talking about external diameters)!

3- Polini uses big lateral transfers as well as a monstrous bar exhaust!

Let's make things clear right away, there is no need to fit this kit with a 13mm SHA carburetor and an original type exhaust... You must absolutely adopt a POLINI crankcase with RACE type valves, but also a 19mm PHBG carburettor, a racing exhaust ideally 27mm in diameter, as well as good electronic ignition and a reinforced crankshaft with 12mm axle!

The result is breathtaking, especially with a variator engine (not a single clutch), you will obtain excellent acceleration, arm-twisting acceleration and high top speeds on your favorite circuits! It goes without saying that a chassis of the height must accompany the beast!

As an option we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
