Progressive spring identification

So my new bike just keeps getting better! All the gauges are working, and when I took my fake tank cover off I found a “progressive suspension “ sticker on the top of my airbox! I checked and sure enough, I’ve got a progressive rear spring! My question is how do I tell if front forks are upgraded as well? The bike rides and handles great, but it would with factory front too right? Anyhow, thanks in advance

The only way I know to check for sure would be to pop off a fork cap and look. If there is about a 6 inch long spacer above the spring you have the stock springs if the spacer is less than 1 inch you have the progressive.
