Ohlins STX36 Mini Rear Shock HO 819 User Manual

Introdução

This manual provides essential information for the proper installation, adjustment, maintenance, and troubleshooting of your Ohlins STX36 Mini Rear Shock, model HO 819. This shock absorber is specifically designed for the Honda Z125M motorcycle to enhance performance and handling. Please read these instructions carefully before installation and use to ensure optimal performance and safety.

Informações de segurança

Always prioritize safety. Improper installation or adjustment of suspension components can lead to loss of control and serious injury. If you are unsure about any part of this process, consult a qualified motorcycle technician.

• Utilize equipamento de proteção individual (EPI) adequado durante a instalação.
• Certifique-se de que a motocicleta esteja firmemente apoiada em um cavalete antes de iniciar o trabalho.
• Do not attempt to disassemble the shock absorber. It contains high-pressure nitrogen gas and oil, which can cause injury if released improperly.
• Use only genuine Ohlins parts and recommended tools.
• Regularly inspect the shock for damage, leaks, or wear.

Configuração e instalação

Verificações de pré-instalação

Before installing the new shock, ensure all components are present and undamaged. Verify that the shock model HO 819 is correct for your Honda Z125M.

Ferramentas necessárias

• Motorcycle stand
• Chave de torque
• Socket set (appropriate sizes for your motorcycle)
• Conjunto de chaves Allen
• Fita métrica ou régua
• Graxa

Etapas de instalação

1. Secure the motorcycle on a stand so the rear wheel is off the ground and the swingarm can move freely.
2. Carefully remove the original rear shock absorber, noting the orientation of all components.
3. Clean the mounting points on the frame and swingarm. Apply a thin layer of grease to the mounting bolts if recommended by the motorcycle manufacturer.
4. Install the Ohlins STX36 Mini Rear Shock (HO 819) with the reservoir facing the correct direction as per the specific vehicle instructions (refer to your Honda Z125M service manual for exact orientation).
5. Hand-tighten all mounting bolts.
6. Lower the motorcycle slightly to allow the shock to settle, then torque all mounting bolts to the manufacturer's specified values. Refer to your Honda Z125M service manual for torque specifications.
7. Ensure there is no binding or interference with other motorcycle components throughout the full range of suspension travel.

Initial Adjustments (Static Sag)

Static sag is crucial for proper suspension function. It refers to how much the suspension compresses under the motorcycle's own weight.

• With the motorcycle on its stand, measure the distance from the rear axle to a fixed point on the chassis (e.g., a bolt head). Record this as Measurement A.
• Remove the motorcycle from the stand and allow it to rest on its wheels. Gently bounce the rear a few times to settle the suspension.
• Measure the distance from the rear axle to the same fixed point on the chassis. Record this as Measurement B.
• Calculate the static sag: Static Sag = Measurement A - Measurement B.
• Adjust the spring preload ring on the shock to achieve the recommended static sag for your Honda Z125M (typically 5-15mm for street use, consult your motorcycle's manual or Ohlins recommendations). Turn the preload ring clockwise to increase preload (reduce sag) and counter-clockwise to decrease preload (increase sag).

Operação e ajustes

The Ohlins STX36 Mini Rear Shock offers adjustable damping to fine-tune your ride. The primary adjustments are rebound and compression dampindo.

Rebote Damping ajuste

Rebote damping controls the speed at which the shock extends after compression. Too little rebound can cause the suspension to feel bouncy; too much can cause it to pack down over successive bumps.

• The rebound adjuster is typically located at the bottom of the shock body.
• Turn the adjuster clockwise to increase rebound damping (slower extension).
• Turn the adjuster counter-clockwise to decrease rebound damping (faster extension).
• Start with the recommended settings in your Ohlins documentation or motorcycle manual, then adjust in small increments (e.g., 1-2 clicks) based on riding feel.

Compressão Damping ajuste

Compressão damping controls the speed at which the shock compresses. Too little compression damping can make the suspension feel soft and prone to bottoming out; too much can make it feel harsh.

• The compression adjuster is typically located on the reservoir.
• Turn the adjuster clockwise to increase compression damping (firmer ride).
• Turn the adjuster counter-clockwise to decrease compression damping (passeio mais suave).
• Adjust in small increments, testing the feel after each change.
