Adjustable keyboard 8x3x70 mm – 2 pins Ø7,4 mm – Compatible OTK

This high-precision adjustable keyboard is specially designed for demanding users in karting and mechanical sports. It guarantees a perfectly stable lock between the rear hub and the axle, ensuring total safety even under the most severe conditions: strong bend supports, high lateral loads, sudden variations in grip or particularly good track use.

Unlike a standard clave, this adjustable version allows not only to secure the mechanical connection, but also to adjust quickly and properly the position of the rear hubs on the axis. This feature is essential to change the grip of the chassis as needed:

• extend or tighten the rear lane,

• increase or reduce the bending of the axis,

• fine-tuning kart behaviour in the inlet, middle or exit phases.

Thanks to this keyboard, the settings become faster, more reproducible and more reliable. A simple manipulation allows the hubs to be repositioned precisely without the risk of involuntary displacement during support. This is particularly important for modern chassis, where the grip often varies from turn to turn and where a slight unsynchronization of hubs can completely change the handling.

Made of high-strength steel, it supports twist, impact and shear stresses without any deformation. The two Ø7.4 mm pins, perfectly calibrated, ensure rigid coupling with the axis and eliminate any parasitic play. The 34 mm spacing between the pins helps stabilize the whole and ensures a direct and efficient power transmission.

Accuracy machining ensures easy mounting, regular sliding and perfect compatibility with systems OTK (Tony Kart, Kosmic, Exprit, EOS, Redspeed, etc.). This clave is therefore ideal for both demanding leisure drivers and competitors looking for a consistent performance lap after lap.
