The Monza chassis competition program, managed directly by the Birel racing department along with some external teams both in the National and International arenas, allowed for efficient development of the KF models (destined for the single-brand lines) and KZ models (categories with gearboxes).
In international competitions, Giacomo Patrono was engaged in the development of the KF version, participating in the principle KF2 competitions, while Manuel Cozzaglio was committed to a program completed by the KZ1.
The result of that commitment is the birth of two new chassis which, starting in 2008, will be integrated in the Monza line that already includes 7 models.
The two new karts were developed for the top competitions and will be identified by the initials ZY 32-A (category KF) and ZY 32-C (category KZ).
They can be considered to be an evolution of the respective ZX versions that, however, will remain in production. The differences mainly concern the technical specifications of the pipes used to build the body: for the new ZY models solutions offering more efficient performance with medium-soft tyres and typical race track conditions were chosen.
Moreover, the bearing support flanges were modified with the introduction of those made by Freeline, already used in the KF and KZ Birel series. Such a solution in respect to the ZX version permits further regulation of the rear axle, among which is its height.
The two new models also include some specific and functional International competition solutions: for the ZY 32-A version, the front-end spindle is the Freeline L 180 which allows for the front brake casing, while both have the external eccentric bushing to facilitate control as well as magnesium rims.
