Generation II

The second generation Family 0 began production in November 2002. It is an updated version of the Family 0 engine and features TwinPort technology – twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy. The crankshaft and oil galleries were also redesigned to lower power loss; thereby increasing fuel economy.
