Gilera Runner 50 PureJet RST (2005 and later)
The Gilera Runner 50 PureJet RST is the second generation of Gilera’s sport scooter, introduced in 2005 with the model’s first major redesign since its launch. It retains the defining feature of the PureJet designation—the fuel injection system that replaces the carburetor found on the SP versions—and is identified by the chassis code ZAPC46200, as opposed to the ZAPC36100 of the previous series. This generation features larger-diameter wheels, a combined analog-digital instrument panel, and a new chassis, all of which directly affect the compatibility of replacement parts.
