CRF450L Suspension Upgrade Fork and Shock Springs
Вставка
- Опубліковано 13 вер 2024
- With a factory weight limit of 220lbs the CRF450L is not sprung for us larger folks. At 6'3" and 235lbs I'm too heavy for it so today we work on upgrading the suspension with new fork and shock springs. We'll show you how we do it if you've never done the suspension your self before. We take the fork springs apart and figure out how to get the rear shock assembly out and the spring changed. If you enjoy the video please be sure to subscribe!

"This is what you have to do when you don't put the bag of chips down" 🤣🤣
Thanks for showing us the hard way :). Between this video and the John T Young video - I was able to get a good idea of what would and might not work so well.
I just upgraded to a 6.3 spring. I wiggled getting it out down to the following steps (with stock tank).
1.)Take off seat and side plastics; 2.) disconnect (press clip and pull) the starter relay plug from where it connect on the side of the ECM holder on the right; 3.) once unplugged remove the seat support cover that sits over the air box and what the ECM is connected to (2 bolts and plastic side release) and set to the side; 4.) remove the muffler (3 bolts); 5.) put bike on stand to unload spring; 6.) unwind the spring tensions, 7.) remove subframe bolts (4) - you may have to lift gently on subframe to take tension of the bolts. 8.) lift subframe up and to the left to make room for the spring to come out. 9.) remove spring and replace per your instructions. 10.) rinse and repeat. Whole thing took about 45 min.
I did use a strap between / around a couple parts of the spring and twisted it with a screwdriver to compress the spring to make it easier to get the clip on and off.
I took my rear shock off to paint the spring on my 450L. I left the front subframe bolts in ( but loose) and pivoted the subframe up to remove the shock. I think I remember thinking it’s possible to remove the lower shock linkage and the swing arm pivot bolt and lower the swing arm ( with the chain still attached and get the spring out that way too. 🤔
The part you have left over , I believe is from the ecu bracket, and one of the two bolts goes through it to mount the ecu to the airbox.
I dropped one of the washers twice behind the starter motor 🥶, but retrieved them with a magnet. 🏁.
Great video, thanks for sharing. I’m getting an fmf rear pipe for mine as you’ll already know how heavy the stock one is.
Bonus tip:, if you’re keeping the stock rear pipe, I removed the rear end cap and cut the small exhaust inner pipe off around 2” , this makes the bike sound much better when you put it back together as the pipe then resonates inside the end cap making its sound much better. 👍🏽🏁
I need to update the comments are you are correct about that bolt, I was looking at diagrams and was able to figure out it does indeed go to the ecu mount! I am hoping I don’t have to take the shock out for a long time but next tine I will try to find an easier way. Looking forward to riding it soon. It was 18 the other morning and I still just don’t enjoy riding in the cold enough to bother
To change just the spring. Release the preload with a drift pin and hammer. Releases the bottom bolt. Then you can remove the retaining clip on the bottom and remove the spring. No need to remove the shock. To remove the shock you can get it through the side just loosening the subframe after the spring is removed. I’ll pull mine again in a couple weeks. Need to revalve the rebound
Excellent comment. I was wondering after wards if I could have gotten to it. I just always pulled it before. Also I am assuming with the spring out you can compress it easy for taking out. This is how you learn!
Dads Domain yes you can compress and remove it then. When I read the manual for removing the shock. I started with the process. I thought there’s gotta be a better way 🙄. It’s all a learning experience.
Jeez I haven’t looked at the manual since I bought it. I really should as it actually had a lot in it
Figured it out, much less wrenching but puting the clip back in was rough. If you have a skid plate with leakage guard take it off before putting the bike on the stand
Liams bike looks siiiiick. My RM80s were the ugliest bikes in 1998, and they are still the same ugly bike. I also liked how you told Liam to "figure it out" when he asked how to open the spring packaging. Life is all about figuring things out. Awesome channel!
Thanks for the compliments, I appreciate it! I really try to make the kids step up a little bit here and there as they get older. Liam will actually be getting a yz85 here real soon and tyler will be getting the 65. I'll put together a video of us getting that because its an unexpected purchase that I fell into but I need to head to Montana for it. I'm not a 100% but I heard that the RM's and KX's were the same bikes for a long time, maybe still are, but with different colored plastics. The gas tanks on those old RM's though remind me of the old yellow yz85 my dad had years ago
I love the bike and the art work on the over head door. good job on the vid. thumbs up.
Having a left over part would keep me up at night, lol. Looks like a bushing of some sort.
My Honda 2022 CRF 450 RL has the most stiffest suspension I have ever rode and felt on any bike in my life it is like a covered wagon 200 years ago!! I had $1,000 worth of suspension work done to it it is still a stiff as a bicycle with no suspension I think I now need to put new Springs in the front spring in the back revolve it start over again I want smooth soft suspension I weigh 200 lb I had the same guy redo all my suspension on my Honda 92 CR500 that suspension is absolutely out of this world
Super easy take the links off the shock and remove the chain and swing arm bolt.
Ooh this is a fun one nice job
Thanks, it was fun to have multiple things going on
Hey guess what I just made a model of the crf 70 transmission out of legos I will make a video on my channel if you wanna see it
Sure we’ll check it out with the kids tonight
Thank you that means so much
Nice.. I want a 450l.. First time I have seen someone take a shock apart. Hopefully I won't have to do it as im just under 200.
If you were racing it all the time you would need stiffer but you might get away without adjusting it.
Ding ding ding what! \m/ agree... I'm with team blue for this sound ✔
Anyone else’s heart stop when they have a screwdriver that close to the forks.
Imagine the feeling if you slipped and took a chunk out of them 😵
It took us a lot longer to do it than I showed for that very reason. I was the most worried at that point. Second one was a lot easier though after doing it once
me did
That spacer, you found, goes in the plastic box that the ecu mounts to.
I eventually figured it out, can’t remember how but I am glad I never throw it away
Lmao 0:55 imagine you’re getting a heart transplant and the doctor says that!😂 I’d be shitting myself 😂
Cool video good info thanks.
After 3 years how did this work out for you? Im 225. Just picked a used 22 RL up. Played the same game with a KTM 790 I have and it was a game changer. Did you end up doing valving or just stick with the springs?
you should install a FMF pipe on the 110
You can get the spring out without taking the shock off the bike
If for any reason I change it again some day I'm going to try that.
So I'm new to the dirt bike world, and I have questions. Why aren't the factory fork springs good enough for your weight? I understand why you need a stiffer rear shock (which I just orders btw), cause that's where most of your weight will sit. Can you explain why you went with a heavier spring on the forks? It's troubling me cause I don't want to mess around with fork seals and oil and all that mess. The rear I feel I can handle, but the forks looks a little too intensive for my level of wrench turning. My weight fluctuates between 210 lbs and 230 lbs, season to season. I guess what I'm asking is: can I get away with changing one and not the other, or will it throw off the balance of the bike?
Edit: I think I found my answer. Used the racetech spring rate calculator, and according to my height, weight, skill level, and riding style, I actually need to go down a peg on the front forks. Got lucky when I ordered the rear spring as I nailed exactly what I need.
Suspension settings are a mix of technical specs, types of riding you want to do, weight, and personal preference. It’s almost impossible to be perfect. I don’t really ride slow technical single track. I am more likely to go to the mx track. On top of my size and preference for a little more firm feel I wanted to go up. I think I have backed off my clickers by 3 and it’s feeling really good to me right now. Ride it stock for awhile. Play with the clickers. Learn what they do. And then if you are still too stiff or soft change you’re springs. And like you found those calculators help too. Good luck!
So did you change the nasty oil Honda puts in the forks ??
No but now you have me wishing I had researched it and put something else in....
dont feel bad Im 6'5 and 260 lbs, working my way down to 240 eventually
240 has become my parking spot. 220 takes a ton of work and hard to maintain. 240 I can hold
How long did that dust seal last?
What weight for your rear spring did you get?
I feel bad for you all covered in snow, my lawn is still green. Well I'm going to get in my hot tub a chillax for a bit y'all try not to freeze.
I need a snow bike kit someday. That would help the season more, but for now we’re jealous!
Take your muffler baffle out and your Honda will sound mean and amazing.
Hi the 65 sounds way better ;)
Yes, yes it does!!
Why can't you just remove the fork tops to change the fork springs?
It’s my understanding that the top of the fork cap is part of a housing that would not give you access to the springs. It contains a lot of the shims and such. Someday I might try taking one apart all the way to work on it further
@@DadsDomain Thanks for the reply! I think my old(er) 1990 Yamaha DT200R has the fancy USD forks beat in that regard! Won't stop me from loving my new CRF450L!
The only thing that’s stopped me from loving mine is snow. But someday I might consider a snow bike kit for the winter
There is a way to change from the top, I did it on my drz400. You have to make a part to hold the shims and spacer to take it apart that way.
Odd Honda has a max weight of 220 lbs. That means NO racks, panniers, or gear. That makes it NOT a dual sport.
I completely agree. Most people won’t pay attention to it but it makes no sense. The first give away though was no passenger pegs
@@DadsDomain Hahaha. Passenger pegs. The bike I replaced with the 450L is a KTM 625 SXC. It has passenger pegs, but the manual clearly says no passenger. Umm... what?
J P The only reason I wanted passenger pegs was to give the kids quick rides. For now they are small enough I just throw them up front around my dads house
Is a doble Chamber???
Yes they are, they are not the triple chamber air forks they used for awhile. They got rid of those
I'm 270lbs. This makes me think I need to just order a beta from the factory and get them to install the factory fat boy springs!
I would go to racetechs website and enter in your info and see what they recommend. I know you can get stiffer fork springs than what I used. But on the rear you would have to see what size is rear spring they recommend for you vs what is available to see if it would work or call around for custom work and then see in the end what costs the most and decide what to do
@@DadsDomain Thanks for the advice. Great tip for a good website. I appreciate it. Nick
@@nickfountain8420 I'm 275 and the bikes fine for me but I just fallow my kid riding and dont do big jumps .I haven't bottom out yet.
@@stevenleininger5682 Hi Steve. Thanks for the info. I appreciate getting any tips I can from folks on these bikes. I'd rather a Honda over a Beta due to not having easy access to a Beta dealer. There's only one in the entire state of Alabama currently. There's a Honda dealer in my city. Easier to get parts with them located nearby I imagine.
Why don't they design this bike the way it should be in the factory why do we always have to clean up there incompament mess IAM buying a. 2022 FR 450 RL Honda Next week I already have to strip down and replace a million things!!!
The list on this bike was larger than anything else I've ever bought before but now that its how I want it I don't see me selling it for a long time!
Why pay 10k for the Homda then spend a grand plus on upgrades? Just buy a Husky/KTM and save $ on the long run.
I'm not going to go there because I've heard they're good bikes but I also have heard of people leaving those brands for Honda because they're cheaper in the end. All I know is Honda is what I know and working on them is pretty easy for me
I almost went with the Husky 501 - but chose the Honda CRF for 2 reasons. Solid subframe & parts / service anywhere- even in tin-buck-two. I owned a European bike and got tired of the 3 week parts delay and 3 hour drive to closest dealer.
Ummmm.......extra parts are never good.
They sure get you thinking though! I eventually figured it out. They help hold the ecu bracket
