Designed using hlins' race-proven suspension technology, the STX 46 provides significantly enhanced damping performance over the original equipment shock while maintaining excellent reliability for everyday street riding and spirited performance use. Built around a large 46 mm monotube piston architecture, the STX 46 is designed to provide consistent oil flow characteristics, improved damping control, and reduced fade during prolonged aggressive riding. Whether navigating urban streets, mountain roads, or long-distance touring routes, the hlins STX 46 offers increased traction, improved stability, and a more connected riding experience. Key Features Genuine hlins STX 46 Street Performance Rear Shock Direct bolt-on replacement for OEM rear suspension Large 46 mm monotube piston design High-pressure nitrogen gas charged Internal gas reservoir configuration Adjustable rebound damping Adjustable spring preload Precision CNC-machined aluminum components Hard anodized body construction for corrosion resistance Low-friction piston rod and seal design Fully rebuildable and serviceable TV approved Manufactured to hlins Racing specifications STX 46 Monotube Technology The STX 46 utilizes a high-performance monotube damping system that separates hydraulic oil from the nitrogen gas charge using an internal floating piston. This configuration minimizes oil aeration and cavitation, maintaining consistent damping characteristics under varying operating temperatures and demanding riding conditions. Compared to conventional twin-tube shock absorbers, the monotube architecture offers several advantages: Improved heat dissipation More consistent damping force Reduced damping fade during prolonged operation Faster hydraulic response Enhanced wheel control over uneven surfaces Increased suspension sensitivity to small bumps The large 46 mm piston diameter provides greater hydraulic control and allows more precise management of compression and rebound forces, resulting in improved chassis stability and tire contact. Adjustable Rebound Damping The integrated rebound adjuster allows riders to tailor suspension extension speed after compression events. Proper rebound adjustment offers significant improvements in: Corner exit traction Chassis stability Rider confidence Suspension composure over uneven pavement High-speed directional stability Control during rapid transitions Fine-tuning rebound damping allows the suspension to match rider preference, motorcycle loading, and varying road conditions while maintaining optimal tire contact with the pavement. Adjustable Spring Preload Mechanical spring preload adjustment enables accurate suspension sag setup for different rider weights and operating conditions. Correct preload adjustment contributes to: Proper ride height Improved steering geometry Enhanced braking stability Better weight distribution Increased cornering precision Reduced chassis pitch during acceleration and braking The included preload adjustment tool allows convenient setup without removing the shock from the motorcycle. Premium Construction Every component of the STX 46 is manufactured using high-quality materials and precision machining techniques developed through decades of motorsport competition. Construction features include: CNC-machined aluminum shock body Hard-anodized surface treatment for corrosion resistance Precision ground piston rod Low-friction sealing system High-pressure nitrogen charging High-performance hydraulic oil Precision shim-stack valving Serviceable internal wear components The design ensures long service life while allowing complete rebuilding and re-valving by authorized hlins service centers. Performance Advantages Installing the hlins STX 46 rear shock provides measurable improvements in motorcycle dynamics. Enhanced Rear Tire Traction Improved damping control allows the rear wheel to maintain more consistent contact with the road surface, increasing available traction during acceleration and cornering. Increased Chassis Stability Controlled suspension movement minimizes unwanted chassis oscillation, resulting in more predictable handling characteristics at both low and high speeds. Improved Rider Feedback The advanced damping system transmits more precise information from the rear tire to the rider, increasing confidence during aggressive riding and improving overall control. Reduced Suspension Fade Efficient heat management and superior hydraulic design maintain consistent damping performance during extended rides where conventional shocks may experience degradation. Superior Ride Comfort Improved compliance over road irregularities reduces rider fatigue while maintaining excellent chassis composure.
