Ielasi Tuned GP9R Spec2 WC 2024 9-ports .21 OS Base Modified On-road engine
new GP9R24 engine compared to the GP9R23WC has a new, exclusive IELASITUNED piston which allows us to have a tighter piston/cylinder coupling than the WC, (but at the same time facilitates the running-in phase of the WC engine), this allows us to maintain better compression even when hot. Obviously the GP9R24 will already be relased with the new "R" reinforced connecting rod, shaft with different timing and balancing to attenuate internal vibrations, engine backplate and inner head revised in configuration and cooling head with the new 2024 graphics.
