SENSOR 4S AND SENSOR 4S PRO

PERFECTION THROUGH SIMPLICITY

CORE Sensor 4S und Sensor 4S Pro

With the Sensor 4S and Sensor 4S Pro, CORE continues to evolve its control system with a clear focus on precision, functionality, and durability. Clean design, purposeful features, and uncompromising quality form the foundation of the unmistakable Sensor feel – developed for maximum control and performance in every situation. 

Based on experience gained over recent years, the Sensor 4S has been purposefully refined in key areas. A new bar made from carbon‑reinforced high‑performance polymer delivers increased robustness and load capacity while reducing weight. 

Revised Sensor 4S lines, developed exclusively in collaboration with Liros, provide significantly more direct feedback combined with increased durability. The update is complemented by a consistent grey‑yellow signal coding for improved orientation, as well as new service inserts that can now be replaced without disassembling the bar for the first time.The FlexTrim clamp integrated into the floater, allowing easy backline adjustment directly while riding. 

TWO ModeLS. One System.

CORE Sensor 4S Bars System

Sensor 4S

The Sensor 4S is aimed at riders who prioritize maximum reliability and precise feedback. The new Liros lines offer increased stiffness, reduced stretch, and a consistently direct steering feel – ideal for the majority of riders. 

CORE Sensor 4S Pro Bars System

Sensor 4S PRO

The Sensor 4S Pro takes things one step further. Equipped with Tectanium 2 lines, it delivers even more direct, uncompromising feedback with minimal diameter and maximum strength. Developed for riders who demand the highest level of performance. 

“With the Sensor 4S and Sensor 4S Pro, we are continuing the success story of our control system. We have consistently evolved it, taken customer feedback seriously, and purposefully refined key details – always with the goal of maximum precision, highest reliability, and functional clarity.”

MAXIMUM SAFETY AND VERSATILITY 

The proven SFS+ safety system ensures full depower via a single front line – without residual pull. In combination with the 4:1 adjuster, it is one of the safest systems on the market. 

The High V / Low V line split allows the bar to be adapted to different riding styles and setups in seconds. Universal pigtails also allow easy compatibility with a wide range of kites. 

CONTROL DOWN TO THE LAST DETAIL 

The Auto Untwist system with ceramic ball bearing keeps the front lines perfectly untwisted at all times, while the 4:1 adjuster enables precise trimming with minimal effort. 

Stealth winders, adjustable bar width, and smart details such as spliced line ends and premium materials result in a consistently clean, durable, and high‑performance setup. 

 

BUILT FOR THE HIGHEST DEMANDS 

High‑performance polymers made in Europe and marine‑grade stainless steel metal components guarantee maximum stiffness, corrosion resistance, and longevity. 

The new carbon‑reinforced high‑performance polymer bar sets new benchmarks in stability and weight. The revised CIC quick release features optimized ergonomics and reliable function under load for maximum safety.
