FRSP ST4466 43.2 x 657mm

This is a spring for the SFF and also suits the Spring Conversion Kits ( Shock Treatment and Krooztune ) for the AER Fork

Springs are the most critical element of suspension performance. Ideally they should be matched to suit the combined weight of both bike and rider. Correct spring rate will ensure that the bike settles to the ideal ride height to determine the final geometry of the motorcycle.(Rider Sag)

So what makes a good spring?

Ideally it should be;

• Made from the highest quality chrome silicon spring steel
• Press a high stiffness to mass ratio.( lightweight )
• Be shot peened, heat treated and preset to length.( set to solid )
• 100% tested prior to supply to the end user.

Spring installation details are on the Shock Treatment web site

There is a variety of spring manufacturers on the market but for the fussiest riders there should be only one choice.
