For riders looking for a substantial performance increase for their water-cooled 125cc Kymco 4-stroke engine, there is now a gritty performance set from NARAKU performance. The bore of the cylinder was increased to 62mm and now gives a capacity of 175cc, which clearly lets the torque of the engine be felt. Now Kymco enthusiasts can keep up with their Italian counterparts when it comes to over bored cylinder kits. Kit contains all necessary mounting parts. The crankcase must be also be shimmed out, as on other big bore kits. The 125cc cylinder head is retained.
