MONSTER EVO 3, A WINNING TRADITION
The Formula K Monster EVO is a chassis which, in recent years, has become a point of reference in the 60 Mini category. The first “signal” came with the victory of the 2016 WSK Super Master Series and the performance on the track has always been at the top, as substantiated by the excellent results in the races of the first couple of months in the 2020 season. It was inevitable that in the year of the first CIK-FIA homologation dedicated to the MINI class, IPK was ready with the third version of its kart reserved for younger drivers, updated both technically and aesthetically.
As per the regulations, the Formula K Monster Evo 3 frame is made of 28 mm diameter tubes that are manually welded. The chassis design has not changed compared to the past, reinforcing the two curves on the longeron at the fuel tank height, a feature that all major manufacturers have introduced in the 2020 homologation. The first innovation of the 2020 model is found in the rear axle with the new bearing housing which offers an additional height adjustment feature, for a total of four in all, for the fastening of the flange.
A change that also involves the C5 bearing (additional smoothness), is now equipped with 3 axle fastening grub screws. The added grub screw allows the grip to be more significant by distributing it over 120 degrees, a major modification which aims at solving one of the most common problems in the Mini 60: the fastening of the grub screws to an axle with a thinner width.
The new plate for the fastening of the fuel tank has two rings for the route of the fuel pipe.read more
The axle bearing housing features three grub screws, this distributes the force exerted on a thin axle thickness such as that of the 60 Miniread more
As support for the master cylinder, IPK has introduced an open housing, a solution which increases the rigidity of the support structureread more
The muffler support is no longer anchored to the bearing flange casing, so as not to affect the chassis flexion which remains unchangedread more
The footrest is an important accessory for the Mini category karts as its multiple adjustments allow it to adapt the driving position to the different heights and growth of the younger drivers.read more
The careful attention to details by IPK technicians is displayed in a secondary modification concerning the tubes, shortened and reduced in diameter, to which the supports of the side fairings and front spoiler are fastened to. Thanks to these changes, it was possible to eliminate a previously present Teflon bushing. Moreover, on the more purely technical side, this solution leaves the chassis freer, reducing the tension that is generated in making it integral with the fairing support. The fastening system was revised as well, allowing the screws to be tightened without ovalizing the chassis tube. In regard to the chassis, emphasis should also be placed on the introduction of the casing for the support of the master cylinder which replaces the previous welded plate. The new solution allows a better alignment of the pump with respect to the brake pedal, as well as increasing the rigidity of the support structure.
