The Top Performances 70cc Cast Iron “Due Plus” Cylinder Kit Piaggio NRG / Runner is one of the best 70cc cast iron available for the NRG / Runner. With the right configuration (21mm carb and racing exhaust), the “Due Plus” can reach about 15/16hp – definitely record-breaking for a cast iron 70cc cylinder! This cylinder kit has a lot of torque and is very powerful in the high rpm ranges, making it the perfect cylinder for pilots who are looking for maximum performance with a cast iron cylinder. In order to preserve the reliability of the engine we highly recommend using a reinforced racing crankshaft, at least from the mid-range segment.
