JESOLO APACHE A CHASSIS WITH A UNIQUE DESIGN


















CIK-FIA 2012 - 2017

HOMOLOGATION
The approval of the Jesolo Apache expires in 2017. However, everything is ready for its renewal

KZ - KZ2

CONFIGURATION
The chassis is suitable for use with both non-shifter and shifter engines. The photos show the KZ version

30

TUBE DIAMETER
Typically, 30 mm and 32 mm tubes are used. Either all the same size or a mixture. The Apache’s tubes are all 30 mm

MANUAL

WELDING
There are two “schools of thought”: by hand or robotic. The Jesolo Kart is manually welded

MAGNESIUM

ACCESSORIZES
Magnesium accessories with bars and a few other parts made out of aluminium, on the Apache by Jesolo

It is often said that "These days chassis are all the same". Not always. The Apache model produced by Jesolo Technology Kart, for example, has an absolutely revolutionary frame design

Let’s forget everything we know about kart chassis! Let's start from scratch. Let’s dare! This must have been the mantra of Jesolo Technology Kart when designing the Apache chassis, undoubtedly the most unconventional product in the last decade of kart approvals.
The project was led by Gianluca Giacchetto, owner of the company, respected constructor for many years and all-round "karting man": "The main objective during the design phase - he explained - was to keep the weight as close to the ground as possible in order to increase smoothness on bends, which is a vital factor for a successful frame".
To achieve the objective, Jesolo’s engineers created a chassis with a single outer tube folded twelve times in sequence ("An act of madness performed using a tube bender..."), placed entirely on one axis: a "unique" solution for the current karting scene, in which all chassis have different height longeron tubes at the front and the rear.
This innovative feature is accompanied by the position of the central crossbar that, unlike traditional chassis, is not joined to the outer tubes, but rather to the inner ones.

    The central crossbar is joined to the chassis’ inner tubes. By mounting the left sidebar (photo inset), it can be turned into a "four-tube" chassis, concentrating the weight in the central area of the chassis

    There are two versions of the Apache chassis: the first, which is CIK-FIA approved, has the front end welded to the outer tube, while the second, called USA-Hobby (pictured), is not welded, but bolted to the chassis so that it functions as a roll bar. This also allows quick height adjustment and the possibility of completely changing the front end with one of a different hardness, depending on the type of rubber used

    The outer chassis of the Apache consists of a single 30 mm diameter tube bent twelve times, which allows the weight to be kept as low as possible on the front end compared to traditional chassis

    The design of the frame showcases the countless curves of all the main tubes in the chassis: a bona fide philosophy for the Apache by Jesolo Technology Kart

    The extension created to join the central crossbar to the left side permits an additional square-section bar, de facto transforming it into a “four-tube” chassis. “The research on concentrating the load ‘inside’ the chassis – said Giacchetto – produced positive results, especially on the traction of the kart with the wheels straight“. With the driver on board, the forces are distributed equally, not just on one are of the chassis: this factor helps during the set-up of the kart and is more noticeable when there is less grip out on the track.
    The “round theme“, created in the design of the frame and present in all main 30 mm diameter tubes, contrasts with another innovation introduced on the Apache: square-section bars, used for the two additional bars and the supports for the seat and the tank. Slots are machined at various heights so that cables and fuel pipes can be positioned inside, keeping the area tidy.
