Front forks too spongy

So one of the things I've noticed while riding is that the front suspension feels a little soft. What is the best thing I can do to stiffen the front suspension?

I wanted something easy to install, drop in and use so i decided to go with Intiminators and preload adjusters from Spearsracing.

If your spring rates are correct, you can adjust your preload either with adjustable preload fork caps or cut the internal spacer to the correct size. This should also be in conjunction with getting your sag to the correct setting.

You can also change the oil to a heavier one, add more, or a combo of both.

Intimidators are ok but require a lot of work once you start getting into the realm of tweaking your rebound settings as you need to take the caps off, fish out the intimidator, tweak it, put it back in, check oil level, reinstall the cap, then go for a ride. I have never owned gold valve emulators but the process is pretty similar.

Cartridge kits are well worth the money imo. There are several kits out there. I went ohlins due to no alterations required to the forks themselves.

From the sounds of it, cartridge kit seems like the way to go....

I donīt do track days, just multi surface roads, like dual sport riders. I installed a pair of the Ricor Intiminators that I had purchased direct from Ricor just this week. Since they do not have a specific product for the MT-03 (R3) I measured the inside diameter of my fork tubes to make sure we had a good fit. They included two additional pairs of over sized sealing rings since the diameter of my fork tubes was slightly more than their 41mm Kayaba design. I went with Ricorīs advice to keep the OEM .66 kgf/mm springs in but I changed those out today to the Racetech .80 and I prefer that setup for my weight. Dive is significantly reduced at all speeds with both the OEM springs and the Racetech. On cobblestones, the ride feels somewhat harsh same as OEM, but not a problem. At speed, the bike is well planted and tracks true. Of course once you "fix" the front suspension, you will notice how crappy the rear suspension is. I think it is best to do both the front and rear, or you will not get the full benefit of the modified front suspension. I installed a Hyperpro progressive 460 shock today and it is a good match with the new fork setup. If you are a track rider and have the coin, then cartridges would be a better option, because of ease of tune. Most of it depends on how you are going to use your bike.

Whatever you choose, remember that suspensions work best in a narrow range. If a suspension shop promises you that they will transform your bike across all road surfaces at all speeds, then hold on to your wallet. There are always some compromises with tuning a suspension.

+100 on this. Great info.
I do mostly street riding, but I am going to a track day in September to see how I like the track. My main concern is that the front seems to dive really quick on initial front braking, especially if it's anything more than feathering in the brake.

For track use, oem suspension is still ok for beginner group. Heck, there's some guys running fast laps in races too. I went full cartridge kit and ohlins rear shock for my race bike. That allows most tuning range, and can adapt for multiple track layouts.... fast long corners versus short stop and accelerate hard layout
