Common questions
How do I know if the 0.90kg spring rate is right for my Sportster?
Spring rate depends on your rider weight, riding style, and any additional load. We recommend consulting a suspension specialist or using Race Tech's guidelines to confirm the ideal spring rate for your specific setup before ordering.
Will these fork springs require any other modifications?
While these springs are a significant upgrade on their own, for the most comprehensive performance improvement, consider pairing them with Race Tech Gold Valve Emulators to fine-tune your damping.
Are these springs difficult to install?
Fork spring replacement typically requires specialized tools and a good understanding of front-end suspension. If you're not comfortable performing the installation yourself, we recommend having a qualified mechanic do it.
