The famous and very famous kit POLINI liquid 70cc for MOTOBECANE AV10 engine! We've been calling for reproduction for 15 years! POLINI finally decided to listen to the enthusiasts by leaving a small series! We booked a nice part of the small production with our friends of the factory POLINI for our customers!

The ultra coupled and powerful kit from the market! The passionate kit par excellence!!!!! It is a kit that works on everything, even on small configurations, and it is a kit that becomes a real demon once prepared!!!! Prefer aluminum, finishing, honing, applause, and processing GILARDONI / POLINI to the lower-end competitors of the market, you will not be disappointed!

This high quality cylinder is made in GILARDONI and treated nicasil on these new versions (better than the chrome of the time), we will also enjoy the architecture of the canals that is excellent. Basic level, big transfers are present, so you will have to align your carters with them, they are not necessarily useful to this unprepared kit because it has very small diagrams you must admit! You can earn a lot of power by raising the diagrams of at least 10° to 20° for the exhaust while following the admission. The piston delivered with this kit is a very good model with high silicon content, mono segment to allow the highest speeds, this piston also has a small preparation for improved sweeping, lateral greases to avoid side heaters and scrubs.

The head is a hemispherically polished high compression model. This kit preserves big assets such as the 6 real transfers (no blinds), the exhaust in W, the single segment exhaust, the aluminum material.. This kit is therefore a very good very torquey model that can achieve very high speeds with good engine preparation (to be performed by professional or connoisseur, the W and the treatment takes care and time).
