Kit 70cc Ø47,6mm (axis of 10mm) aluminum SIMONINI Hyper Racing minarelli vertical (booster rocket, bws, ...)

Unapproved part! Only reserved for competition, circuits and closed tracks.

 

Finally available at home the famous kit of the Italian house SIMONINI racing model hyper racing exhaust booster. Very high-quality aluminum treated nykasil the cylinder is bored has a Ø47,6mm, it has a very robust Nykasil treatment and intake / exhaust diagrams based on 50/50% torque / high speeds, you will have a very good couple and excellent high regime. The booster exhaust will give you more strength than a bar exhaust and it will allow you a very good top speed thanks to a maximum opening width of the exhaust. This cylinder has 6 transfers, the intake is reviewed and corigated, much larger in the low case inlets, we strongly advise you to add a big valve to your configuration with this type of cylinder.

The piston is prepared as it should, it is manufactured at vertex (luxury version with high silicon content) in mono segment end chrome hard curved to allow the best high speeds while maintaining excellent compression. We can compare it to the various high-end kits like the MHR, polini evo ... at the same time more solid and sometimes better finished. A real kit capable of surpassing many competitors! This cylinder will be an excellent base for engine preparation. Even the finish is really on top! You can push it a little more with the help of an exhaust preparation.

 

Attention, kit delivered without cylinder head! You can also buy the piston model 12mm axis.

 

We recommend at least to accompany this kit : Simonini hyper racing exhaust or equivalent model, Ø21 minimum carburation, competition spark plug, crankshaft and reinforced bearings, Simonini racing cylinder head or equivalent model.

Optionally we offer a preparation Stage 1, this preparation is a modification of the channels and the exhaust light by increasing the diagram and improving the duct, it increases the performance of the cylinder. An improvement of the piston and skirt stocking is also included in this modification as well as work on the admission. Allow a little extra time for this preparation!
