The DR Racing Evolution 70ccm cylinder kit is a good solid cylinder kit in the Sport class. The design means that there is good traction at low revs and combined with e.g. a Top Performances Powered exhaust, you will experience a marked improvement in both traction and top speed. The cylinder is, just like the original, made of cast iron and can therefore be used over many kilometers. For this cylinder a spark plug with a long thread must be used - we recommend an NGK BR8ES . The kit is delivered complete incl. gaskets, piston rings, etc.
