Key Specifications & Features

1. Model & Fitment

2.  Designed for Yamaha Aerox (305 mm rear shock length). 

   • Part of RCB’s SB-5 series of “dual absorber” shocks.

    

3. Build & Materials

   • High-pressure nitrogen gas type: According to Shopee listing, this SB-5 is a gas-charged shock. 

   • Piston / Damper Size:

     • Big damper piston diameter: 35 / 46 mm. (Based on Shopee spec.) 

     • Piston rod diameter: 14 mm (from same Shopee spec). 

   • Body: Alloy / full-alloy body 

1. Adjustability

   • Spring Preload: Adjustable. (Allows you to stiffen / soften the spring depending on load or ride style.) 

   • Rebound Damping: Also adjustable. (Controls how fast the shock “rebounds” after compression.) 

2. Dimensions

   • Length / Eye-to-Eye: 305 mm. (Common for Aerox rear shocks) Finish / Aesthetics

   • Colour: White version. (Model name explicitly mentions “White”.) 

   • Looks sporty and cleaner — the white finish can match well with bike bodywork, depending on the color scheme.

3. Performance / Behavior

   • Because of the gas charge + adjustable damping + preload, this shock is likely to offer better control over bumps and more tuned ride feel than stock Aerox suspension.

   • The dual-absorber / gas type design helps with maintaining rebound and damping under load, giving more consistent behavior.

4. Installation

   • According to sellers, it's a bolt-on setup for Aerox, so installation should be straightforward for someone who knows what they’re doing. 

   • No major modifications are typically required when replacing stock shock with this one (as per product descriptions). 

5. Brand Credibility

   • RCB (Racing Boy) is a well-known brand in the performance / race parts segment, especially for two-wheelers.

   • Their shocks are commonly used as upgrades for scooters and small bikes, and SB-series is part of their “dual absorber” line.
