Key Features
Power Lines by LIROS
Durable, stiff, and precise LIROS power lines give the Sensor 4S dependable control feedback with the strength and reliability expected from a premium CORE bar system.
Carbon Long-Fiber Bar
A long-fiber carbon-reinforced high-performance polymer bar improves stiffness, robustness, and load resistance while maintaining the clean Sensor feel CORE riders love.
Click-In Service Inserts
Replaceable click-in inserts in the bar center help reduce wear and simplify maintenance, allowing service without fully disassembling the bar.
FlexTrim Backline Tuning
FlexTrim is integrated into the floater and allows quick backline fine-tuning directly at the bar, making small adjustments faster and more intuitive.
SFS+ Single Frontline Safety
The SFS+ safety system flags the kite on one frontline for a clean release and adds compatibility with both fixed-bridle and pulley-bridled kite designs.
4:1 Adjuster
The proven 4:1 trim system makes depower adjustments fast, smooth, and precise with less effort, especially useful in stronger wind or changing conditions.
Auto Untwist
Automatic below-the-bar front line untwist helps keep lines clean after spins and rotations, reducing clutter and improving control system feel.
Universal Pigtails
Universal pigtails make setup easier and help expand compatibility, making the Sensor 4S a practical option for CORE kites and many other kite models.
Performance Feel
Precise Without Being Complicated

Easy to Tune
High/Low V line split, Vario line lengths, FlexTrim, and adjustable bar width let you tune the bar for kite size, wind strength, riding style, and personal preference.
Reliable for Everyday Sessions
