Frequently Asked Questions

How do I know what spring rate I need?

Spring rate depends on your weight, riding style, and fork geometry. Race Tech offers 500+ rates — contact them with your bike details for a recommendation.

Will these improve my bike's handling?

Yes. Proper spring rates restore chassis balance and predictability, especially if your bike was under-sprung from the factory.

What does 'no sacking-out' mean?

It means these springs maintain their rate over time and miles. Shot-peening and heat treatment prevent compression set and fatigue.

Do I need any special tools to install these?

Fork spring installation requires disassembly of the fork tubes. Most riders have a shop handle this work, or use a fork spring compressor tool if doing it yourself.
