Piece unapproved! Only reserved for the competition, with closed circuits and tracks.
Finally available from us the famous kit 70cc 7 transfers of the Italian house SIMONINI racing. In high-end aluminum cylinder is bored a 47,6mm, it has a very robust treatment nykasil and torquey enough intake charts. 3 back transfers, diagrams, normal exhaust (part of) special form make a couple of monster.
The piston is prepared as it should be, it is manufactured at vertex (luxury version with high silicon) in mono chrome domed end hard segment to enable the best diets high in preserving a great compression. This kit is a true weapon acceleration torque and recovery, it is also pretty good at high speeds but all the same less than its big brother in racing version to boosters. Transfers channels are extremely well drawn and in combination with the admission of 3 transfers back the perfect scanning. On these models engines (minarelli vertical) it is quite hard to make out the power in particular because of the admission of the cylinder and air cooling.
On this one, SIMONINI has learned of such admission maximum performance, the three rear transfers are not here to trade but rather to increase the quality and scanning performance. A real kit able to overcome many competitor! This cylinder serras an excellent base for the engine preparation. Even the finish is really on top!
Attention kit comes without head! You can also buy the piston axis 12mm model.
We suggest at least to accompany this kit: Exhaust Simonini racing or similar, minimum Ø21 carburetor, racing candle, crankshaft and reinforced bearings, Simonini racing cylinder head or equivalent.

Optional we offer a preparation course 1, this preparation is a modification of the channels and the exhaust port by increasing the chart and enhancement of the duct, it increases the cylinder performance. Improved piston and bottom skirt is also included in this modification as well as work on admission. Allow a little extra time for this preparation!
