The Birel is to the Karting as the Ferrari to the Formula 1. they Represent both the winning Italian technology in the world. And in the world of the karting, the Birel has always been sensitive in to develop new roads, parallel to the development of the products racing. From this philosophy was born the Division Endurance 4 year ago. 

So that the loom N35 x has been developed, that has in the structural sturdiness and in the facility of guide its own principal characteristics. And to guarantee to all the teams the perfect product, in 2003 the new motor Birel has also debut, the first one to 4 times specify for the kart and the first projected and realized from the Lissone's house. 

The first unity engine to 4 times thought and projected for the karting. It has in the acceleration and in the couple to the low regimes, its own points of strength. In comparison to the motors employees in the last editions, that guaranteed only little elasticity and the good couple to the tall regimes, the new motor Birel has been conceived for having all the in demand characteristics. 

This shrewdness allows to also annul the small possible differences between motor and motor and to avoid at the same time too elevated speed in rectilinear. The select configuration allows to also get chronometric reliefs of 6 inferior seconds in comparison to the trail season and to also satisfy the expectations some most experienced conductors.
