The spider offroad rear adjustable linkage system will improve rear grip and feeling on your 2023 to 2025 KTM SMR450 or Husqvarna FS450 supermoto bike. The linkage has been designed to make the rear suspension work in a more linear way. The oem linkage is designed for motocross and is very progressive (soft at first, then harder). The spider linkage makes thinks much more linear and generally allows the use of a softer spring with more feel from the rear of the bike and ultimately more grip.
Tested by the supermotoland race team at GP level, the spider rear linkage is a must have for any serious racer, as improving rear grip allows you to get on the gas earlier and harder.
The linkage also allows you to adjust rear ride height easily and quickly by swapping out different offset bushes to raise or lower the rear of your bike. making quick geometry adjustments possible.
