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 Giannelli GO exhaust, you will experience a marked improvement in both traction and top speed. The cylinder is, just like the typical original cylinder, made of cast iron and can therefore be used over many kilometers, this combined with a strong bottom drive, makes the DR Racing Evolution 70ccm cylinder kit an obvious and very useful choice for everyday use.
A spark plug with a short thread must be used for this cylinder - we recommend an NGK BR8HS . The kit is delivered complete incl. gaskets, piston rings, etc. Note: ø10mm cross pin.
Specifications
NOTE: The cylinder kit is with ø10mm cross pin. In order to guarantee that this cylinder fits on your machine, we recommend that you measure your current cross pin.
Note: The cylinder can not be mounted on models from 2003->, unless the restriction in the engine block has been removed. If the cylinder is mounted, it is no longer possible to use the original, or other Euro2, exhaust. Both parts apply to models from 2003->. This does NOT apply to PGO engines.
