🛠️ 3. Complete description of the product seat seat OTK Flat Fiber Flat - The Official Reference for Chassis Tony Kart & Kosmic

Optimize your driving position and the dynamic behavior of your kart thanks to headquarters OTK fiber flat. A true spine of your chassis, the choice and positioning of the tub determine at more than 70% the distribution of the masses and the efficiency of your rear train in turn.

Designed by the Race of the Italian factory OTK, this model stands out for its flat bottom design. This technical geometry makes it possible to anchor the seat closer to the bitumen and to lower the pilot's center of gravity, a major asset to stabilize the kart during the phases of large braking and limiting the excessive side grip on the tracks. Overloaded with gum. Made of high performance resin and fiberglass, this tub offers the exact flexibility required by the manufacturer to allow the tube to work freely, while maintaining perfectly the hips and ribs of the driver during the lateral G forces.

👨🔧 4. The trick in Michel (the corner of the expert)

* "Hi the artists of the trajectory! The tub OTK flat-bottomed fiber is the only one and only seat you need to mount if you want your Tony Kart or your Kosmic to work as the factory has planned. Chassis OTK are developed around the flexibility of this precise seat; Put another brand or a cheap copy is the best way to deregulate the machine.

My indispensable mechanical trick for mounting your seat: manufacturer ratings and support washers !

First absolute rule: do not mount your seat at the pifterometer ! OTK provides an ultra-precise dimension table (for example, the distance between the back shaft and the top of the tub, or the distance relative to the front train tubes). Take out your ribbon meter, take the measurements of the millimeter and attach it exactly according to the factory recommendations. An error of 1 cm forward or backward can turn a hunting plane into an anvil on the track.

Second booth board: The seat is fiberglass. When you go drill the tub to pass your fixing screws, use wide nylon or rubber washers (seat cups) between the metal screw head and the fiber. If you tighten raw metal directly on the fiber, the massive vibrations of the engine will crack the tub in two sessions. A seat mounted in millimeter and amortized, it is the insurance to snap a pole position without having pain back! "*

❓ 6. FAQ SEO (Frequently Asked Questions)

Q: Why choose the "Flat Background" version rather than a rounded standard seat ?

A: The flat-bottomed design has been specifically developed for adult competition categories. It offers a lower seat surface, which allows you to lower the pilot body to the maximum to the kart floor. This reduces the roll of the assembly and is particularly effective to release the rear yard when the track is very hot and gum loaded (avoids that the kart jumps or raises the internal wheel too much).

Q: how to choose the right seat size OTK in the drop-down menu ?

A: Sizes OTK usually range from numbers or letters (1, 2, 3, 4 or 1 plus, 2 more etc.). To make the right choice, measure the width of your hips with your race combination and coast protection (coast vest). The tub must keep you firmly without compressing the bones to avoid bruising, while avoiding being too wide for you to slip from one side to the other in turn.

Q: Is this fiberglass seat delivered with the fixing screw kit ?

A: No, the seat is sold naked (without prior piercing to adapt to your exact morphology). Seat scrapping kits, wide aluminum or nylon cup washers and rubber spacing holds are available separately in our "Chassis Accessories" category.
