Frequently Asked Questions

What's the difference between Standard and Heavy Duty versions?

Standard springs suit stock-weight riders and moderate loads. Heavy Duty springs accommodate heavier riders, passengers, or luggage without excessive compression.

Do these reduce front-end dive when braking?

Yes — the progressive rate resists initial compression, so the front end stays higher during hard braking compared with stock springs.

Is installation difficult?

Fork spring replacement requires fork disassembly and is best left to a qualified technician. Most shops charge $200–$400 for labor.

Are these covered by warranty?

Yes — Progressive backs these springs with a lifetime manufacturer warranty against defects.
