Key Features Genuine hlins STX 36 Twin Rear Shock Set Specifically engineered for Harley-Davidson XR1200 and XR1200X STX 36 Single Tube Technology 36 mm piston diameter Monotube high-pressure nitrogen gas construction External piggyback reservoir Adjustable rebound damping Adjustable compression damping Adjustable ride height Adjustable spring preload Precision CNC-machined aluminum construction Hard-anodized components for corrosion resistance Fully rebuildable and serviceable Manufactured in Sweden STX 36 Race-Derived Suspension Technology At the heart of the hlins STX 36 is a 36 mm high-flow piston operating within a monotube hydraulic body. The high-pressure gas design separates hydraulic oil from nitrogen, reducing cavitation and maintaining stable damping characteristics even under aggressive riding conditions. Compared to OEM suspension, the STX 36 offers: Improved suspension response Increased rear tire grip Superior bump absorption Enhanced cornering stability Reduced suspension fade More consistent damping under heavy use Improved rider feedback The advanced hydraulic design keeps the rear wheel planted, improving both performance and rider confidence on demanding roads. External Piggyback Reservoir The integrated piggyback reservoir increases oil capacity and improves thermal stability, allowing the suspension to maintain consistent performance during prolonged spirited riding. Benefits include: Increased oil volume Better heat dissipation Reduced damping fade Improved hydraulic consistency Superior performance during aggressive riding Enhanced suspension longevity This configuration is ideal for riders who regularly push the limits of the XR1200 chassis. Adjustable Rebound Damping External rebound adjustment allows precise control over suspension extension speed following compression. Proper rebound tuning improves: Corner exit traction High-speed stability Suspension recovery over uneven pavement Chassis composure Rider confidence Overall handling precision The easily accessible adjuster enables quick suspension tuning to match rider preference and road conditions. Adjustable Compression Damping Independent compression adjustment allows the rider to tailor suspension firmness during bump absorption. Compression tuning optimizes: Brake stability Impact absorption Chassis support Cornering precision Passenger comfort Ride quality over rough pavement Together with rebound adjustment, compression tuning provides a highly customizable suspension setup. Adjustable Ride Height Integrated ride height adjustment allows chassis geometry to be fine-tuned without affecting spring preload. Benefits include: Faster steering response Increased lean angle clearance Improved weight distribution Enhanced agility Customized riding position Optimized handling characteristics This feature is particularly valuable for riders seeking maximum performance from the XR1200 platform. Adjustable Spring Preload Threaded spring preload adjustment allows proper suspension sag to be established for rider weight and intended use. Correct preload adjustment contributes to: Balanced chassis geometry Improved steering feel Better braking stability Increased cornering confidence Enhanced traction Maximum suspension effectiveness Proper setup ensures the suspension operates within its designed travel range for optimum performance. Premium Engineering Every hlins shock absorber is manufactured using precision machining and premium materials developed through decades of international motorsport competition. Construction highlights include: CNC-machined aluminum bodies Hard-anodized corrosion-resistant finish Precision-ground piston rods Low-friction seal head assemblies High-pressure nitrogen charging Precision shim-stack valving Premium hlins suspension fluid Replaceable internal wear components The fully rebuildable architecture allows complete servicing and re-valving, making the STX 36 a long-term investment in your motorcycle's performance. Performance Benefits Superior Cornering Performance The STX 36 provides exceptional rear wheel control, reducing chassis movement and allowing the motorcycle to maintain its intended line through corners. Increased Rear Tire Traction Improved hydraulic control keeps the rear tire in contact with the pavement, maximizing grip during acceleration and corner exit. Enhanced Rider Confidence Consistent damping and improved chassis feedback create a more predictable motorcycle that inspires confidence at all speeds. Improved Ride Comfort The advanced damping system absorbs road imperfections more effectively than the factory suspension, reducing rider fatigue without sacrificing performance. Reduced Suspension Fade The monotube gas-charged design and external reservoir maintain consistent damping performance even during extended aggressive riding. Technical Features STX 36 Single Tube Technology 36 mm piston diameter Monotube high-pressure gas construction External piggyback reservoir Adjustable rebound damping Adjustable compression damping Adjustable ride height Adjustable spring preload Fully rebuildable design Multiple spring rates available for rider-specific setup Exact shock length and spring specification vary depending on the selected XR1200 application and hlins part number. Fitment Designed for: Harley-Davidson XR1200 (20082012) Harley-Davidson XR1200X (20102013) These motorcycles represent Harley-Davidson's most sport-focused Sportster models, featuring upgraded brakes, chassis geometry, and suspension designed for aggressive road riding. Installation The hlins STX 36 Twin Rear Shock Set is designed as a direct replacement for the factory rear suspension using OEM mounting points.
