KLX 300 SUSPENSION | REPLACING FORK SPRINGS | MOTION PRO DAMPER ROD BLEED TOOL | SUSPENSION UPGRADE

In this video I show you how I replaced my front fork springs on the KLX 300. The 2024 KLX 300 is easy to work on and upgrade your suspension. I got the front fork springs from Race Tech. They have a calculator on their website to get the correct spring rate. Motion Pro makes a Damper Rod Bleed Tool that will help you get this job done quick.

Thanks very much for taking the time to make & post this video. I'm 5'10", 220 and have a lot of experience on a heavier KLR trail riding. The first time I rode my '24 KLX300 and let off the throttle in first gear standing up, I wasn't expecting it and remember thinking I was going over the handlebars because it dove so sharp just on decel. Calculator ended up suggesting a .52 KG/mm rate (vs. the .38 KG/mm stock spring). FWIW, I didn't need the motion pro damper rod tool since I put the bike up on a lift & removed the front wheel. That allowed me to move the forks up & down (independently) to fetch the damper rod. When I needed the fork to stay fully compressed, I fashioned a bungee to keep it up. The tool would be very handy otherwise. Also, my cap used a 30mm socket instead of 32mm. Concerning the fork oil, Racetech suggested 90mm from the top and after taking out the stock springs, it was so close already I didn't need to add or remove any fork oil. I didn't use the washers that came in the racetech box, nor did I have to fab any spacers like other fork springs in bikes require. This was "plug & play". For others considering this, a reminder to retain & reuse the "washer" (a.k.a. fork spring guide) that sits between the top of the stock springs & the fork caps. Rear shock is still stock for now, maybe upgrade it later. But this has improved the handling so so so much its unbelievable! I don't mean to hijack your post, just thought of some things others may have questions about. I've changed springs in 2 bikes before, but no 2 are the same. Your video helped save a lot of time & unnecessary steps. Ride Safe and Thanks Again Derek!

[@DerekDualSport]

This is awesome advice, I appreciate the post! It definitely makes a world of difference on these bikes.

[@Hans_Brick]

@@DerekDualSport That's for sure!!! I'll use your other "how to" video on the rear shock spring upgrade if need-be in the future... For now, I've adjusted the preload on the OEM rear shock to get me by. Good Stuff & Take Care!!!

[@tieoneon1614]

Wow....I had no idea it was that easy. Watched both your vids replacing springs and now I feel dumb for never doing it on my previous 2. Id love to see a video comparing how it feels.

[@DerekDualSport]

Hey now you know. I think if I was sticking to the streets I could survive with the soft stock suspension. But I love riding trails and being over 250lbs those stock springs just don’t cut it.

[@tombledsoe8880]

Air bleeders on the front forks work wonders on that bike to stop the initial harshness once the forks get up to temperature

[@stoplogicmotorsports]

Wish they wouldn't have cheaped out and removed em, the old school KLX300r ones may work as the part number is the same

[@lhv13098]

Also, I just did the front. Thank you for both videos on how to do the front and back.

[@shaymtbrider7244]

Do pvc pipe trick will work ?

[@andy3d1]

Nice - you make seem so easy! I'm going to upgrade my KLX230R :)

[@DerekDualSport]

You can definitely do it!

[@SqueakyCheeks23]

Thanks for doing this. Looks easy enough.

[@DerekDualSport]

No problem! I am glad that it helped!

[@jamesschiller2054]

Great video! Do you feel like there is any need to change valving or have springs been all that was needed for the suspension?

[@DerekDualSport]

Just changing the springs was enough for me. It made a huge difference.

[@samleary2733]

As a fellow not small guy, pretty awesome to see your feedback on the small dual sport. I have been wondering if it would still be a solid choice for a 6’+, non stick figure guy and you are making it harder and harder to not pick one up

[@nickspatoulas2422]

How do you bleed these forks?

[@TheBostonVan]

Video was lit my guy

[@DerekDualSport]

Thank You! 🙏

[@multycam]

Just out of curiosity, can you replace the Front springs the same way on a Suzuki DRZ400S the same way?

[@DerekDualSport]

It should be very similar.

[@andycornerstone2094]

This is the info I've been needing. I just bought a klx300, picking up later this week. I am a big boi too (6'4" & 245lbs), what other upgrades do you have planned to make this bike more big boy friendly? Shocks, pegs, handlebar, and barkbusters are first on my list

[@DerekDualSport]

Ohhh yeahhh! If suspension is first on your list check out Race Tech for Front Springs, and Cogent Dynamics for rear (they had the thickest rated rear spring I could find). Handlebars I went with Pro Taper CR HI bend and Tusk 30mm risers. (This set up doesn’t require you to change stock cables) pegs I went with IMS super Stock they are much wider. I got size 15 feet and they work for me. I should have the pegs, handle bars and risers linked in the description.

[@isa_31967]

Hey man kinda lost I spent all night trying to find some that fit my 2023 but I can’t find anything

[@austinhans1685]

What are the washers/shims that come with the Racetech fork springs used for?

[@Assorted12]

What rate spring did you use?

[@DerekDualSport]

.61kg from race tech

[@Assorted12]

@DerekDualSport Thank you. I'll call when I order my spring to ensure I'm getting something right for me.

[@codybruce3864]

Do you have a link for the springs themselves

[@DerekDualSport]

racetech.com/ProductSearch/12/Kawasaki/KLX300/2024

[@DerekDualSport]

I got them from Race Tech. When you get on Race Tech’s website there is a calculator that asks you questions like your weight, skill level etc. Fill that out and it will let you know which spring rate they recommend. I’ll link to their page.

[@codybruce3864]

@@DerekDualSport thanks a lot dude. I appreciate it! Looking forward to more content
