Produk Selesaiview

The image displays a pair of Ohlins HD 159 OHL STX 36 Twin Shock Absorbers. Each shock features a silver-colored main body with black springs coiled around it. The top and bottom mounting eyes are visible, designed for secure attachment to a motorcycle. The overall appearance is robust and engineered for performance.

Fitur Utama:

• 1/2 in. length adjustable: Allows for fine-tuning of ride height and geometry.
• 36mm piston: Provides excellent dampkarakteristik.
• Hard anodized, precision CNC-machined components: Ensures durability and precise fit.
• High-pressure nitrogen gas charged: Maintains consistent damping performance under varying conditions.
• Low-friction shaft/seal head design: Reduces wear and improves responsiveness.

Pengaturan dan Instalasi

Proper installation is crucial for the performance and safety of your Ohlins shock absorbers. If you are unsure about any step, consult a professional mechanic.

Alat yang dibutuhkan:

• Motorcycle lift or stand
• Set kunci pas soket
• Kunci torsi
• Pin tool for preload adjustment (supplied with shocks)
• Pita pengukur
• Sarung tangan dan kacamata pelindung

Langkah-langkah Instalasi:

1. Siapkan Sepeda Motor: Securely place the motorcycle on a lift or stand so that the rear wheel is off the ground and the swingarm can move freely.
2. Lepaskan Shockbreaker Lama: Carefully unbolt and remove the existing shock absorbers. Note the orientation and any spacers.
3. Install New Ohlins Shocks:
   • Align the top and bottom mounting eyes of the Ohlins shocks with the motorcycle's mounting points.
   • Insert the mounting bolts. Do not fully tighten yet.
   • Ensure all spacers and washers are correctly positioned as per your motorcycle's service manual.
4. Penyesuaian Awal:
   • Penyesuaian Panjang: The shocks are 1/2 inch length adjustable. Adjust the length to achieve the desired ride height. This is typically done by rotating the lower eyelet or a dedicated length adjuster.
   • Preload Adjustment: Use the supplied pin tool to adjust the spring preload. Turn the preload rings to compress or decompress the spring. Refer to the "Operating and Adjustments" section for detailed preload setting.
5. Baut Torsi: Once the shocks are in place and initial adjustments are made, torque all mounting bolts to the specifications provided in your motorcycle's service manual.
6. Pemeriksaan Akhir: Before riding, ensure all bolts are tight, and there is no interference with other motorcycle components.

Operasi dan Penyesuaian

The Ohlins STX 36 Twin shocks offer several adjustment options to fine-tune your ride for different conditions and rider preferences.

1. Rebound Adjustment:

Rebound damping controls the speed at which the shock extends after compression. This adjustment is typically located at the bottom of the shock body. Turning the adjuster clockwise increases rebound damping (slower extension), and counter-clockwise decreases it (faster extension).

• Terlalu sedikit rebound dampsedang: The motorcycle may feel bouncy or unsettled, especially over bumps.
• Terlalu banyak rebound dampsedang: The shock may "pack down" over successive bumps, leading to a harsh ride.

Start with the recommended factory setting (refer to the specific model's documentation if available) and adjust in small increments, testing the feel after each adjustment.

2. Penyesuaian Beban Awal:

Spring preload determines the initial compression of the spring and affects the ride height and sag. Use the supplied pin tool to rotate the preload rings. Compressing the spring (turning rings to reduce spring length) increases preload, raising the ride height and reducing sag. Decompressing the spring (increasing spring length) decreases preload, lowering the ride height and increasing sag.

• Pengaturan Sag: Sag is the amount the suspension compresses under the motorcycle's weight (static sag) and with the rider on board (rider sag). Proper sag is critical for optimal handling. Consult your motorcycle's manual or Ohlins guidelines for recommended sag values.
• Adjusting with Pin Tool: Loosen the top lock ring, then use the pin tool to rotate the main preload ring. Once adjusted, tighten the lock ring against the main ring to secure the setting.

3. Penyesuaian Panjang:

The 1/2 inch length adjustment allows for fine-tuning of the motorcycle's geometry. Increasing the length can quicken steering, while decreasing it can stabilize the front end. This adjustment is typically found at the lower mounting eyelet. Loosen the lock nut, rotate the eyelet to adjust length, then re-tighten the lock nut.

Pemeliharaan

Regular maintenance ensures the longevity and optimal performance of your Ohlins shock absorbers.

Pemeriksaan Rutin:

• Kebersihan: Keep the shock absorbers clean, especially the shaft and seal area, to prevent dirt and debris from damaging the seals. Use mild soap and water, then rinse thoroughly.
• Inspeksi Visual: Regularly inspect for any signs of oil leaks, damage to the spring, body, or mounting points. Check for loose bolts.
• Bushings and Bearings: Check the condition of the mounting bushings/bearings for wear. Replace if excessive play is detected.

Interval Servis:

Ohlins shock absorbers are precision components and require periodic service. The exact interval depends on usage (e.g., street vs. track, mileage, riding conditions). As a general guideline, it is recommended to have your shocks serviced by an authorized Ohlins service center every 20,000-30,000 miles or every 2-3 years for street use, and more frequently for aggressive riding or racing.

Service typically includes: inspection, fluid replacement, seal replacement, and re-gassing with nitrogen.
