Performance Stage6 70cc cylinder Regarding performance, the Stage6 R/T 70cc Cylinder Kit MKI Piaggio NRG / Runner reaches 20 to 22hp and can easily be placed among the top 70cc high-end racing kits on the market. The thermal properties are excellent - the combustion chamber is bolted to the cylinder at five points, each coming with its own cooling pocket. These highly critical areas are thus stabilized and the risk of piston seizure is minimized. Notes on installation The 70cc cylinder must be fitted with an 85mm long stroke crankshaft, we recommend the Stage6 crankshaft. The crankcase must be opened up a little to make room for the cylinder base (D. = 56.1mm +/- 0.1mm, 10mm deep). A manual is included. The cylinder fits only on the Stage6 R/T exhaust for Piaggio without further modifications due to the angle deviating from the original. WITHOUT HOMOLOGATION / STREET APPROVAL.
