Key Feature Snapshot

The 4S Update

Sensor 4S PRO

Developed for maximum performance

  • Even more direct, firmer bar feedback 
  • Tectanium 2 lines: thinner, stiffer, exceptionally strong 
  • Highest precision under maximum load and demanding maneuvers 
  • For riders who feel every nuance. Who access performance without compromise

Sensor 4S

Ideal for most riders

  • Precision, comfort, and durability in perfect balance 
  • Optimized for direct, reliable bar feedback 
  • New low‑stretch Liros power lines for clean power transmission 
  • Built for freeriders who demand uncompromising functionality

PRO LEVEL PRECISION. INTUITIVE SIMPLICITY.

With the Sensor 4S, we consistently evolve our control system. Based on years of experience, selected details have been purposefully refined. 

A  carbon‑reinforced high‑performance polymer bar delivers greater robustness and load capacity. Stiffer, more durable Sensor 4S lines provide even more direct feedback. The updated color concept features consistent grey‑yellow signal coding on the left side across both bar versions. Revised service inserts in the center can now be replaced without disassembling the bar. The FlexTrim clamp integrated into the floater enables easy backline trimming without untying. 

QUALITY BUILD

TECTANIUM® 2 VARIO LINES - CORE Sensor 4 Pro Bar
Sensor 4 Pro - Tectanium 2 Vario Lines

LINES MADE BY LIROS 
 Your most important connection

Our flying lines stand for highest quality, maximum breaking strength, and minimal stretch. This delivering a consistent flying feel even under high load, with precise steering and reduced trimming effort. Durable by design. As direct after years of use as on day one.  

Adjustable length. Fly at 18, 20, 22, or 24 meters with the base 18m lines and two extensions. 

 

POWER LINES MADE BY LIROS (Sensor 4S) 
More direct. More stable. More durable. 

Customer feedback flowed directly into development. The result: new power lines for the Sensor 4S, approximately 10 percent stronger in diameter, noticeably stiffer and more robust – for even more precision and reliability in every session. 

 

TECTANIUM 2 LINES (Sensor 4S Pro) 
Thin – yet brutally strong. 

The Pro version is equipped with Tectanium 2 lines – thinner, even stiffer, and extremely high in tensile strength. Steering inputs are transmitted instantly and uncompromisingly – for maximum performance under the highest loads. 

Griploc - Sensor 4 Pro Bar

GRIPLOC 2
 Maximum grip. Increased durability.

Abrasion‑resistant EVA grip with clear side identification. New colorway: less prone to dirt and improved visibility. 

 

ISO certified Quick Release
 Officially 100% safe

Since 2020, CORE has been actively involved in the GKA‑led standardization of safety requirements for quick releases. ISO 21853 defines release forces not only in dry conditions, but also under demanding circumstances such as heavy sand contamination, high loads, and extreme temperatures. It also regulates material thickness and color coding to ensure intuitive, brand‑independent operation. 

CONTROL & USABILITY

Core Sensor 4 Pro Bar - Auto Untwist

AUTO UNTWIST
Perfectly untwisted front lines

The ceramic ball bearing below the quick release automatically untwists the front lines. Low friction. Low maintenance. Proven. 

4:1 Adjuster - CORE Sensor 4 Pro Bar System

4:1 ADJUSTER
Less force. Maximum effect.

The 4:1 ratio reduces the required trimming force by 75 percent. 
Precise, smooth, step‑less trimming – even in the upper wind range. 

CIC Quick Release - CORE Sensor 4 Pro Bar System

FLEXTRIM
Backline fine‑tuning without untying.

The FlexTrim clamp integrated into the floater enables backline trimming directly at the bar – even without untying. 

CORE Sensor 4 Pro Bar System

BAR WIDTH ADJUSTMENT
50 cm / 46,5 cm

The rotatable steering line attachment hidden in the bar ends allows bar width adjustment with a simple finger click – perfectly tuned to your kite size. 

 

VERSATILITY

CORE Sensor 4 Pro Bar - Single Frontline Safety

100% SINGLE FRONTLINE SAFETY (SFS+)
 Universal safety – for fixed & pulley bridles

The IKO‑certified SFS+ safety system fully flags the kite on a single front line – without residual pull. 
Compatible with fixed‑bridle kites such as Pace and Air as well as all CORE pulley‑bridled kites like XR and Nexus. 
In combination with the 4:1 adjuster, it is one of the safest safety systems on the market. 

CORE Sensor 4 Pro Bar - Low-V / High-V

HIGH V OR LOW V LINE SPLIT
Adaptable to your riding style

Switch between high and low V in seconds. High V is the standard setting for all CORE kites. Low V is ideal for short lines and radical riding. 
More freedom. More possibilities. 

Core Sensor 4 Bar System - Universal Pigtails

UNIVERSAL PIGTAILS
Easy compatibility.

Universal pigtails make line length adjustments simple and allow easy compatibility with many kites on the market. 

RELIABILITY

CIC Quick Release - CORE Sensor 4 Pro Bar System

REVISED CIC QUICK RELEASE
Reliable release.
Fast reassembly.

Intuitive. ISO-certified. Reliable. 

The CORE Intuitive‑Connect Quick Release functions reliably under load as well as with slack lines. The revised fork lever ensures consistently comfortable click‑in. The green indicator reduces the risk of accidental mis‑release. 

more FEATURES

Sensor 4 Pro Bar Compact

SENSOR 4S PRO COMPACT
For small kites and big wakestylers

An optional shorter 45 cm bar is available for the Sensor 4S Pro. Using the rotatable steering line attachment hidden in the bar ends, the width can be reduced further to 41.5 cm.

Two advantages:  

Shorter lines give smaller kites more precision — ideal for wave and foil riding. Longer lines give freestylers more control, reducing the risk of over-steering larger kites. 

Sensor 4 Bar - Short Safety Leash

SHORT SAFETY LEASH
EXTRAshort is extrasafe

All CORE bars come standard with the ISO‑compliant Short Safety Leash. At just 55 cm, it is comfortably short yet elastic for easy hooking in and ensures the release mechanism remains clearly visible and perfectly accessible at the front of the harness. Riders who prefer to ride unhooked can alternatively combine the Sensor 4S Pro bar with the longer CORE Pro Leash. 

Sensor 4 Pro - Floater

FREE FLOATER
BETTER STEERING. ALWAYS IN REACH

The floaters end a few centimeters above the bar and are not directly connected to it, enabling the uniquely light and dynamic Sensor steering feel. The floater shape supports buoyancy, while the coated line above keeps the lines optimally positioned even without tension. 

Spliced Ends - Sensor 4 Bar System

SPLICED ENDS
Small detail. Big impact.

Spliced line ends instead of simple stitching ensure higher strength and improved aerodynamics. Line layout is cleaner and smoother. 

Click-In Inserts - CORE Sensor 4S Bar System

CLICK-IN INSERTS
Replaceable without disassembly.

The click‑in inserts of the dual‑channel bar guide act like a lubricant for the coated lines and are designed to be replaced under heavy use in order to maintain consistent functionality. Thanks to the intelligent click‑in system, they can now be exchanged in seconds – without taking the bar apart. 

Sensor 4 Pro Multibag

MULTIBAG
Protection with a system

Foldable MultiBag with accessory compartment and ventilated mesh back. 
Protects your bar while traveling and at the spot. 

High-Quality Raw Materials - CORE Sensor 3S Pro Bar

HIGH-QUALITY RAW MATERIALS
Precision under load

High‑performance polymers made in Europe ensure maximum stiffness, low friction, and high dimensional stability. 
Metal components made from marine‑grade A4 stainless steel guarantee maximum corrosion resistance.
