This model which is part of the BRK (BARIKIT COMPETITION SYSTEMS) range is cut from good steels, it has a reinforced connecting rod which rests on a larger crank pin. Unlike the standard SPORT or COMPETITION model, this vilo has a real big job on balancing and real full masses, blue caps, so it offers a performance gain. It will go very well with your small and large power 50cc or 70cc kits. This vilo with its weight has excellent inertia. Comes with its needle cage.
