The DR Racing Evolution 70ccm cylinder kit is a good solid cylinder kit in the Sport class. The design means that there are good features of low revs and combined with e.g. a Giannelli GO exhaust, you will experience a significant improvement in both the upswing and top speed. Like the typical original cylinder, the cylinder is made of cast iron and can therefore be used over many kilometers, combined with a strong bottom drag, making the DR Racing Evolution 70ccm cylinder kit an obvious and very useful choice for everyday use.
For this cylinder a spark plug with short thread is required - we recommend an NGK BR8HS . The kit comes complete incl. gaskets, piston rings, etc. Note: ø10mm crosswind.
