TESTED DURING ENDURANCE ROUNDS

Since 2000, that is since the birth of the project N 35-X, the organization of Birel group managing Endurance rounds have been using during competitions the new frame designed for renting activities, totalling in 4 years over 400 running hours. Over 30 crews are present at the starting grid of each round and many of them are composed by very beginners. Thanks to this feature, the material tested during the competitions, besides running hundreds of kilometres, was used stressing and straining badly all safety and structural resistance devices installed on the kart.

The functionality of the adjustable pedal and of the driving set-up passed the trials carried out during rounds as well, and of course they proved to be useful to improve many details and to make them more and more functional and effective. The experience on racing tracks was also essential to develop one of the most innovative aspects characterizing the kart N 35-X, that is to say the new pods.

During the first competitive seasons standard pods were adopted, which were not particularly protective as far as rims, spindles, axles and mechanical parts in general were concerned. Since the introduction during agonistic competitions of the pods installed on the version for rent, the damages suffered by mechanical parts have been almost cancelled. The rims and the spindles are protected as well as the frame and even the pods reached unexpected levels of resistance. It is enough to clean the kart carefully to restore its original conditions.

N Series Chassis

Birel has created a department in parallel to the racing department for this product range, focusing on studying, researching and developing the new worldwide phenomenon in indoor and outdoor kart rental and endurance racing. All these new events have one common denominator: they use four-stroke engines. After two years of design and research, Birel is proud to present an innovative kart intended for mass amusement. The entirely new chassis has been expressly designed for rentals and endurance races implementing totally innovative concepts. The extremely solid structure is made of 35 mm diameter molybdenum chromate steel tubes. The new kart can be used for right-engine, left-engine or two-engine versions. Front axle disc brakes ensure perfect deceleration and the 40 mm diameter axle fitted on four bearings spells safety.
