A very solid, torquey kit at a good price. The DR Racing is a bi-segment cast iron kit with a diameter of 47mm so approximately 70cc with a 10mm axle, we recommend it to those who stunt or ride every day (outside France because it is not homologated) because it is really very solid, some do up to 30,000 km by changing the piston every 8,000/10,000 km, the diagrams are very good and the compression ratio is 1:12.5. The piston is prepared, the cylinder head is a polished finish high compression model. A very powerful kit that offers very good acceleration and top speed. Its intake system is excellent and its high-end minacrom cast iron really makes it an amazing kit for the price, moreover the minacrom motors parts is really very precise and efficient. You can expect a power of 8 to 11hp depending on your equipment, your settings and your preparation.
Fairly good compared to these rivals: cast iron polini, cast iron malossi, cast iron parmakit and cast iron top performance. Elected the best kit category value for money / vertical minarelli performance by the RRD team.
Its advantages: the price / solidity / performance / instructions and minacrom treatment
Cons : keeps the original type aluminum cylinder head gasket, no valves or jets, cylinder finish
We recommend it with a minimum : crankshaft / bearings / reinforced cage, racing exhaust, cold competition spark plug, carburetor settings.

As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement of the piston and the lower skirts is also included in this modification. Count a little extra time for this preparation!
