Equipped with a high compression combustion chamber, tapered, polished finish. The piston is a 1mm mono-segment model to have the least possible friction and therefore greater ease in reaching the highest speeds. These diagrams are very well worked, seen upwards to gain a maximum in recovery, acceleration and lengthening. with an almost perfect finish. Clearly this kit is an excellent performance gain without neglecting reliability for time. The whole RRD team was pleasantly surprised to see this kind of kit with such a good finish, all for a low price. It was sold with a set of wedges to best adjust your squish for optimal operation.
