(axis of 10mm) A very solid kit of the house TOP PERFORMANCES, coupleux and very low price. It is a cast iron kit bi segment diameter 47mm so 70cc, we recommend it to those who stunt or rolls every day (except France because not homologated) because really strong, some make up to 30 000km by changing the piston every 8,000 / 10,000km, the diagrams are very good,
the prepared piston and the polished frustoconical high compression yoke as well as the diameter of 47mm gives a very powerful kit which offers a very good acceleration and speed peak. Its admission system is excellent and its high-end treated minacrom cast iron really make it an amazing kit for the price, plus the minacrom motors parts is really very precise and powerful. You can expect from 9 to 11 hp depending on your equipment, your settings and your preparation.
Quite good in relation to these rivals : the cast iron polini, the malossi cast iron, the parmakit cast iron and the cast iron.
Its more: price / solidity / performance / instructions and minacrom treated
Its minus : keeps the original cylinder head aluminum gasket, no valves and nozzles, cylinder finish
We recommend it with minimum : reinforced crankshaft / bearings / cage, racing muffler, competition cold spark plug, carburation adjustments.
