Following the launch of the new Racer 401 RR chassis under the Tony Kart flagship brand, OTK Kart Group has extended the package of innovations introduced with this model to all single-speed products of the Group’s other brands. These include the newcomer, LN Racing Kart, developed from the collaboration with the F1 driver, Lando Norris. After having told you exclusively about the launch of this collaboration (read “VIP test | Lando Norris' first time at the wheel of his LN Four”), we returned to Prevalle, in the province of Brescia, to thoroughly analyse this chassis, which made its debut in the WSK and FIA Karting international competitions this year driven by Ricky Flynn Motorsport.
The same team in which Lando Norris grew professionally in karting and with which he won the 2013 CIK-FIA European Karting Championship and WSK Euro Series titles in the KFJ class (now OKJ), and, in 2014, the CIK-FIA Karting World Championship in KF (today OK).
However, now we are not talking about sporting results, but about the product and, specifically, the LN Four model, the chassis made with tubes all 30 mm in diameter, in a single-speed version, which fully inherits the basic construction philosophy of the OTK Kart Group: “Designed, Engineered, Manufactured 100% made in OTK”. All the components of the LN Four, in fact, are designed, engineered and manufactured entirely within the OTK Kart Group, a company that has been working with largely automated production processes for over 25 years: an approach that ensures almost total uniformity of finished products. This is all to the advantage of performance and operational constancy.
Furthermore, over the last few years the internal processes of the company have further improved, generating a constant path of changes even when the details apparently seemed unchanged from an aesthetic point of view. An example? The company has recently chosen to produce some components, such as the pedal set and bearing shells, made of high quality forged aluminium instead of magnesium. This choice was dictated by the desire to reduce the environmental impact that the processing and treatment of magnesium entail and with the aim of offering consumers a more durable product, as in the case of axle bearing flanges. In this sense the difference between ergal and magnesium is important: the former has better mechanical characteristics including greater resistance and less wear, while the latter has physical qualities such as lower specific weight and higher thermal conductivity, which is why it is used in components that require good heat dissipation such as disc housings, sprockets, rims and wheel hubs.
