Technically speaking, the Polini 84cc Cylinder Kit Evolution 2010 Piaggio NRG / Runner is a Nikasil-plated aluminium cylinder with 6 transfer ports and a divided, bridged exhaust port (new shape). It comes with a top quality one-ring piston (d = 52mm, 13mm piston pin) and a special monobloc cylinder head.
It is the "little brother" of Polini's 94cc kit; it includes the same 52mm diameter cylinder, but with a "standard" stroke (40mm) resulting in this intermediate 84cc displacement. Basically a compromise between a 70cc and a large 94cc, also in regard to performance. It falls into the "Hyper Racing" category.
Note 1: angle of exhaust flange is different from original (flat Piaggio type), it can only be combined with Polini's same series "Evo 2010" exhaust.
Note 2: the kit can only be used with crankshafts with 85mm connecting rods and 13mm piston pins (small end bearing 13x17x17.7mm); the crankcase has to be milled in to make room for the cylinder base!
