Race Tech High Performance 1.00kg Fork Springs - Harley Touring
About Race Tech
Race Tech has been re-valving and re-springing motorcycle suspension since 1985, with Gold Valve emulators and custom-rate springs that let a rider dial damping to their actual weight and riding style rather than a factory average.
Race Tech high-performance fork springs, rated at 1.00kg, are engineered to replace the often-under-sprung OEM units on Harley motorcycles. This upgrade provides properly valved rates for a significant improvement in handling and overall ride stability.
Why riders pick this
- Chrome silicon wire construction for durability
- Shot-peened and heat-treated for consistent performance
- Maintains spring rates without sacking out over time
- Improves handling and ride stability
- Replaces under-sprung OEM units for better control
Many factory Harley-Davidson front ends are under-sprung, leading to excessive dive, vague feedback, and a general lack of confidence when pushing the bike hard. These 1.00kg Race Tech fork springs directly address that issue, offering a firmer, more controlled feel. Riders will notice a sharper turn-in, reduced brake dive, and a more composed ride over varying road conditions. The robust construction ensures these performance benefits last for the long haul.
Robust Construction for Lasting Performance
- Chrome silicon wire construction for superior strength and fatigue resistance
- Shot-peened and heat-treated to prevent 'sacking out' and maintain consistent spring rate
- Engineered to deliver accurate and consistent spring rates for predictable handling
- Designed to improve ride stability and front-end feedback on your V-twin
Dialing In Your Front End
A 1.00kg spring rate is often a good match for many Harley Touring riders, especially those who carry extra weight, ride aggressively, or simply desire a firmer, more planted feel. While these springs offer a substantial improvement on their own, pairing them with Race Tech Gold Valve Cartridge Emulators can transform your front end into a fully adjustable, high-performance system, allowing for even finer tuning to your specific preferences.

Common questions
How do I know if I need a 1.00kg spring rate for my Harley?
Spring rate depends on your weight, riding style, and bike setup. Race Tech offers many rates; we recommend measuring your current springs or consulting Race Tech's spring rate calculator to confirm the correct weight for you.
Will these springs prevent my fork from bottoming out?
Properly rated springs like these 1.00kg units help prevent the fork from bottoming out prematurely, especially during hard braking or hitting bumps, by providing appropriate resistance throughout the travel.
Can I install these without changing my fork oil?
While you can install the springs without changing the oil, it is highly recommended to replace the fork oil with a fresh, high-quality fluid during installation to achieve optimal performance and longevity from your suspension upgrade.
