FASSTEK FORK SPRING

Designed for Yamaha Aerox.

Fasstek Fork Spring – Front Suspension Upgrade

• What it is: A replacement/upgraded front fork spring for the Aerox’s front suspension. It replaces the stock spring inside the fork leg to tune how the suspension reacts to bumps and rider weight.  
• Purpose:
  
• It changes the spring rate compared to the stock fork spring — often stiffer — which can improve how the front end handles, especially under braking or during aggressive riding.  
• A stiffer or performance-oriented spring helps the fork resist bottoming out and keeps the geometry more controlled during rapid compression.  
• Performance Effect:
  
• Better handling: Can make the front end more responsive and stable on rough roads or during hard braking.  
• Ride feel: May feel firmer than stock — you’ll notice less dive under braking and sharper feedback from front suspension compression.  
• Comfort trade-off: Often at the expense of a slightly harsher ride over small bumps compared to softer stock springs. 

In short, the Fasstek fork spring for Aerox is a front suspension spring upgrade that helps control fork movement better than stock, giving a sportier feel and firmer performance when riding aggressively or carrying extra load.
