(10mm axle)An excellent kit that combines performance, torque, tip, solidity, low price, finish... Its high quality cast iron and its reinforced piston gives it a perfect bore as well as maximum solidity, it is very complete with its carbon valve slat, its nozzle, its special reinforced seal pack (O-ring in the cylinder head), its warranty, and these various high-end accessories such as the high-quality alloy cylinder head with a bevelled polished high-compression chamber. It is ranked in power just behind the POLINI corsa 70cc and the top performance cast iron racing.
Its diameter of 47mm, its normal exhaust, its diagrams, its special admission and its two segments offer it a breathtaking torque. We can use it to drive every day (outside France) and do 25,000 km without reboring and 50,000 km in reboring without problems by changing the piston every 8,000 km (available in a, b, c, d same reboring) and also the best for the stunt thanks to its acceleration and its torque as well as its solidity. Peak level, price, torque, acceleration it is relatively up to par or even better and more complete next to these rivals: the Malossi cast iron, the Top performances cast iron, the Parmakit cast iron and the DR racing cast iron. Still excellent, very finished equipment worthy of this great brand that is Polini.
the most: quality, finish, instructions, guaranteed, valves, jet, performance, solidity, O-ring in the cylinder head, excellent diagrams, fuller axis, ...
cons: price a bit high for the range all the same

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!
