Frequently Asked Questions

Why would I need a stiffer fork spring?

Most sportbikes ship under-sprung from the factory for a broad audience. Upgrading to the correct spring rate for your weight and riding style restores balanced handling and front-end feel.

How do I know what spring rate I need?

Race Tech offers over 500 spring rates. Contact the manufacturer or a suspension specialist with your bike model, rider weight, and riding style to select the right rate.

Will I need to revalve my fork cartridge?

Spring rate alone does not require revalving, but many riders pair spring upgrades with cartridge work for complete fork tuning.

Is installation difficult?

Fork spring installation requires removing the fork leg and accessing the spring chamber — typically a job for a shop with fork tools, though experienced DIYers can handle it.
